What is a metal cutter

Metal cutter for drill

The router is used for processing metal and wooden surfaces. But if sandpaper is also suitable for processing wood, then the first thing that comes to mind for processing metal is a file.

Metal processing with a cutter

However, a set of metal cutters would be a better solution.

What are rollers?

Roller cutters, or bevel cutters, are an attachment for a drill that has a tip that is structurally similar to a file. Conventionally, it can be called a file, but such an attachment has many design features that distinguish it from its progenitor.

Roller cutter for metal

Since the drill makes rotational movements, we had to abandon the standard file shape in favor of round, conical and spherical ones. The idea of ​​creation, like many other inventions, is to simplify human labor. Processing metal with a file takes many times longer and requires significant physical effort. Using a drill speeds up the process and requires less effort. In the photo you can see all the variety of cutters offered by specialized stores.

Advantages

The biggest advantage of a bevel cutter over a file is its speed. The bofrez is capable of processing steel at speeds of up to 60 thousand revolutions per minute. It is simply impossible to achieve such a speed manually, which means that the file is significantly inferior in this parameter.

Hole machining

When using a file, great effort is required to achieve the desired result. Of course, when using a cutter, you need to press the drill against the working surface, but this requires much less effort, since greater friction compensates for physical force.

Another significant advantage of a cutter over a file is the alloys being processed. Only soft alloys can be processed with a file; the rest will be difficult to process, and a colossal amount of time will be spent on them. At the same time, the bevel cutter can handle any job. The reason for this is the above-described advantages of working with a drill.

The last advantage, but no less significant, is the greater scope of application compared to a file. Of course, there is a huge variety of files. But one bevel cutter attachment has great potential and can process metal even in the most difficult to reach places. Do not forget that such attachments are smaller than a file, and their use for processing small holes is ideal.

Thus, a metal cutter for a drill has all the advantages over a file, which can be considered a thing of the past century.

Types of bevel cutters

Today on store shelves you can see a large number of different cutters that are suitable for any type of work and can satisfy the needs of the most selective buyer.

However, such diversity came with time. Initially, cutters in all their appearance resembled files adapted for a drill. But with the development of demand, many offers appeared. Today the market offers the following types of bevel cutters.

Sharoshka happens:

• abrasive for metal;
• for metal with diamond coating;
• carbon steel;
• from hard alloys;
• for grinding wheels.

In this case, the type of cutting on the head of the cutter plays an important role. The quality of the work done depends on it. For this reason, there are 4 types of slicing:

• universal;
• thin;
• extra-thin;
• for work on aluminum.

Types of cutters

The form itself provides access to certain places and details. In addition, thanks to the variety of cutter shapes, a wide variety of grinding and cosmetic work is possible.

At your discretion, you can order a cutter of any size and shape, but these can be found in any store:

• spherical;
• cylindrical;
• conical;
• hyperbolic.

Roller shapes

The variety of cutters can raise a logical question among a non-professional: which cutter to choose for a certain type of work? Therefore, the main types of bevel cutters will be discussed below.

Abrasive cutter for metal

This type is produced in the shape of a ball, cylinder or cone. The advantage of the abrasive material is its ability to process metal, glass, ceramics and plastic. In addition, such cutters can be used not only with a drill, but also with screwdrivers, engraving machines and other equipment for this purpose.

All the characteristics described above make this material universal and indispensable in grinding work. Only abrasive cutters have a wide range of applications and are therefore the most common and popular.

Metal cutter with diamond coating

This type of bevel cutters is popular among craftsmen and experts in the craft. Thanks to diamond sputtering, the hardest metals and their alloys can be processed. In addition, these bevel cutters can be used to grind not only hard, but also very soft materials. Diamond spraying does not leave visible marks on the material being processed and, due to its structure, prevents cracking of brittle materials.

Diamond-coated cutters are much less common. But they can be called the choice of professionals who use them in a certain number of cases.

Which brand should you choose?

The question is very relevant, especially considering all the diversity and large selection in our time. However, there are certain representatives whose reputation and quality are not questioned.

Metal cutters “Fit” are a striking representative of the combination of two important components: price and quality. For a reasonable price, you can choose cutters for any type of work. The carbon steel from which the bevel cutters are made will last an incredibly long time and will not fail at a crucial moment.

In addition, Fit offers mini metal cutters, which will be indispensable for processing small holes or small surfaces. Also, due to their size, they gain access to all work surfaces that are not available to their standard counterparts.

In addition, a set of metal cutters is an excellent gift for a man, which he will definitely like.

All the variety of Fit cutters can be seen in the photo.

Metal cutter - is it possible to do without it?

Many people confuse these attachments with cutters. Yes, the tool is similar, but there are fundamental differences:

• Unlike a cutter, a metal cutter is not designed to create specific shapes (end, hole, groove). The nozzle is used for rough or finishing processing, and is an auxiliary tool.
• A router bit is very rarely used in hand tools (in the sense that it won't fit into a drill you hold in your hands). But with a roller cutter, on the contrary, it is more convenient to work without fixing and guiding devices.
• The cutters perform grinding functions, so the working surface is abrasive. A milling cutter is more of a cutting tool consisting of sharp edges. Even if the cutter is similar to a milling cutter, the shape and arrangement of the cutting teeth are fundamentally different.
• Using a metal cutter, you can correct flaws that arose during basic processing, adjust mating parts, tidy up the edge of a workpiece, sharpen a small tool, and perform many more tasks that require a file or needle file. In some cases, perform work on stone or metal using a cutter, faster and more convenient than using a file. To understand what cutters are, let’s look at the different types by shape. The illustration shows their main types:
  

  Which roller cutter is intended for what?

Designed for boring holes or machining ends at a fixed angle. This attachment is also convenient for cleaning (leveling) the inner corner. A smooth end is better for this. Another application is cutting blind holes (without the risk of deepening).

If the end of the cutter is spherical, with working notches, some functions will be unavailable, but it will be possible to save money on purchasing a full-fledged sphere. That is, you have both a cylindrical and a round nozzle.

If you have a diamond or corundum cutter, using a cylinder is convenient for sharpening a tool, especially a compact one. Indispensable for tidying up the screwdriver blade.

Sphere

In addition to processing the sharp edges of holes, using a ball-shaped nozzle, you can perform a variety of grinding or stripping jobs.

For example, make the internal weld seam beautiful, especially at an angle of 90° or less. With this tool you can easily remove point defects: drops of metal left after welding, or streaks of old paint.  

Of course, all this can be done using grinder attachments. What if access to the treated surface is limited? Then the drill (or dremel) is in hand, and the universal abrasive ball will clean the most inaccessible places.

Oval

This is a kind of compromise between a cylinder and a sphere. While maintaining versatility when processing point zones, an oval-shaped metal cutter can already clean the end side of the workpiece.

Another advantage of the shape is that internal cavities can be processed without leaving deep grooves. This feature is appreciated by fans of tuning internal combustion engines.

For example, manual boring of the intake manifold is done with just such a tool. For such work, ordinary abrasive tips, rather than diamond ones, are better suited.

Parabola

It can be with a rounded or sharp head. The rounded bit is great for creating grooves and cleaning out thin spaces (such as oil lines or transmission hydraulic plates). But with the help of a sharp parabola you can remove burrs on the edges of the gears.

Of course, using such a nozzle is convenient for leveling surfaces with limited access. The angle of the working area allows you to compensate for the diameter of the drill.

The parabolic nozzle also allows you to clean welds on internal corners where a sphere or oval cannot reach.

Tongue of flame

Perhaps the most versatile attachment. There is also a rounded head of a parabola or sphere, a barrel-shaped working surface of an oval and the ability to work at an angle, like a parabola.

In the hands of a master, a metal cutter of this shape can work wonders. Moreover, no fixation of the electric drill is required. It is the presence of degrees of freedom that allows processing of the most complex surfaces.

Countersink

A specialized cutter designed for chamfering the edge of a hole. For example - for a countersunk screw or internal threading.

The indispensable tool has two main angles of attack: 60⁰ and 90°. Without a countersink, you have to bore the holes with a larger diameter drill. In this case, the edges turn out to be wavy (features of the design of the working edge of the drill).

And with the help of a cone cutter, a chamfer of an ideal shape is removed, and it is much easier to dose the force.

Clearly, the main areas of application of cutters, depending on the shape, are shown in the illustration:

In addition, small cutters are successfully used in engraving on stone, glass and metal. Both threaded metal and diamond tips are used.

Metal cutters for a household drill: types, rules for selection and operation, useful tips - SibNovStroy

Roller cutters or burrs have been used by humans for decades, and perhaps the history of this tool goes back hundreds of years. There are no sources on this matter.

This invention of the human mind is a special attachment made of various metals, with the help of which cleaning, grinding, surfaces, and crushing of materials are carried out.

Where can you use a cutter?

The cutter is used in many industries - construction, jewelry, mining, automotive, medical and other industries. There is no limit to the variety of these attachments.

A similar tool can be used to process metal and stone, plastic and wood. And if somewhere for more thorough cleaning you can use files or other similar tools, then, for example, to bore the cylinder head in any car, only cutters are used. Therefore, every car enthusiast should have a set of such tools in his garage.

When making plastic windows, you also cannot do without a burr in order to make the welded joint of the plastic profile as clean as possible. Roller cutters are used in the production of glass products - bottles, jars and other things.

The mining industry uses cutters with large diameters and high-strength teeth that enable powerful machines to crush stone with ease. For household work, small-diameter cutters are used, which are installed on an electric drill or other similar tool.

Perhaps many have seen how an engraver works, applying memorable inscriptions to various objects and souvenirs, the material of which is glass and stone, gold and silver, metal, wood and other materials. But few people have wondered why the master so skillfully makes such memorable inscriptions.

And this is still the same roller cutter, but smaller in size and of different shapes. The dental office also uses cutters, thanks to which the doctor has the opportunity to provide high-quality treatment and prosthetics to teeth.

In everyday life, any man who is intimately familiar with plumbing will say that without a cutter, which is an attachment to a drill, it is impossible to make a chamfer, install or remove a door lock, and perform a lot of other necessary operations.

Using a cutter, you can make a clean hole in glass and ceramic tiles, brick and stone, plywood and chipboard, and clean welding seams in places that are difficult for a file to reach. When installing window hinges and handles, you will also need a cutter. To work with different materials, devices are used that differ in their shape and material of manufacture.

What types of burrs are there?

A burr, a roller bit or just a roller cutter are made of different designs and from different metals.

By design they are:

• single-cone;
• double-cone;
• three-cone.

The shape of the head of this device can also be very diverse - in the form of a cone, cylinder, spherical, oval or semi-oval. The use of one or another cutter depends on the material of the workpiece and the task being performed.

Depending on the material, cutters made from:

• carbon steel;
• with diamond coating;
• abrasive spraying;
• carbide.

Balls made of carbon steel are most often used when working with a hand drill, electric drill or screwdriver.

With the help of such burrs, you can get new clean and smooth holes of various configurations or increase the diameter of existing ones. These tools are the most affordable and, as a rule, are most often used in everyday life.

Diamond-coated cutters are a more professional tool, used for the finest grinding and boring. These cutters are best used when working with materials that are not particularly durable - glass, ceramics. At the same time, a diamond-coated burr is also used when processing high-strength materials, where a carbon steel cutter cannot cope.

A burr with an abrasive attachment is not much different from the previous tool in terms of its area of ​​application. The size and shape of this cutter can be very different. Used in conjunction with an electric drill, screwdriver or hand drill. Can be used with engraving equipment.

Carbide cutters are used mainly in production where processing of hard materials is required - cast iron, heat-resistant steel, titanium alloy, stainless steel and other metals. Carbide cutters are excellent for processing welded seams. These attachments are used when working with powerful tools where the number of revolutions exceeds several thousand.

How to choose cutters

The choice of such a tool depends on the intended work, what material will have to be worked with, and what specific operations are expected to be performed. Modern tools, as a rule, are all powered by electricity, where high speeds are maintained.

Therefore, when choosing a cutter, you should take into account the characteristics of an electric drill or screwdriver, their power and rotation speed. Surface treatment often depends on the chosen type of cutting of the cutter teeth, which can be:

• thin;
• universal;
• ultra-thin;
• for working on aluminum.

Carbide cutters should be used when processing non-ferrous metals. If you plan to process soft metal, you need a tool with a head with a reinforced sharpening. For harder materials, a diamond-ground cutter is used.

Using such a tool makes it possible to obtain a perfectly flat and smooth surface. In addition, much less time will be spent on such work, and the cutter head itself will serve for a long time.

There are burrs in which the head can be double sharpened, which has a positive effect on the efficiency of the processing of any metal surface.

But in order to always have the right cutter on hand, experts recommend purchasing sets that contain several types of burrs with different head shapes, differing both in material and in the method of sharpening them.

How to properly use cutters for power tools

In order for working with this device to bring maximum satisfaction, it is necessary to follow some rules that will extend the operating time of both the cutters themselves and will not cause harm to power tools.

1. It is necessary to maintain full contact between the cutter and the surface being processed, but you need to work with the cutter so that its tail part does not touch the surface being processed, since this can lead to the destruction of the junction of the head and the main part of the tool.
2. Do not apply strong physical pressure to the cutter during operation. If excessive pressure is applied, the rotation speed of the electric drill decreases, as a result of which the tool may overheat, which will lead to its rapid deterioration, and the processing process itself will be reduced.
3. You need to choose the right processing speed. At high speeds when operating a power tool with a cutter, the formation of surface unevenness and burrs is eliminated. In addition, the correctly selected operating mode will increase the service life of the electric drill and reduce energy consumption. In addition, at high operating speeds of the drill, the phenomenon of jamming of the cutter in the material being processed is eliminated, and corners and grooves can be processed more carefully.
4. Like any tool that comes into contact with hard surfaces, cutter heads are also subject to wear and abrasion. And first of all, the cutting elements, that is, the teeth, suffer. To extend their service life, it is necessary to use a special lubricant, which is periodically applied to the head of the cutter. The lubricant will prevent overloading of the power tool and will help the cutter glide better over the surface being processed. In addition to lubrication during operation, it is recommended from time to time to immerse the cutter head in a liquid suspension, which can be liquid wax or synthetic machine oil.

If the burr head is severely worn, the tool must be changed. Otherwise, you will need to make strong physical efforts to achieve the desired result. And this is fraught with damage to both the cutter itself and the power tool.

Tips for treating various surfaces

Large industries have their own instructions and requirements on how to use burrs, but our task is to tell you, dear readers, how these devices should be used in everyday life.

Stone cutter

When processing stone surfaces, be it natural stone or artificial, which can be ceramic tiles, porcelain stoneware or marble, it is necessary to wet the treated surface with water.

And here it is important to ensure that moisture does not get on the operating power tool in order to eliminate the risk of electric shock. Supply wires, cables and their connections must be well insulated and located away from water.

Wood cutter

When processing surfaces made of wood or similar materials (multi-layer plywood, chipboard, fiberboard), cutters that have large notches or teeth are used.

In addition, it is necessary to choose the correct operating mode for an electric drill or screwdriver, because when working at high speeds, such a side effect as setting the tree on fire is possible.

Each power tool has a dial for adjusting the number of revolutions. If you smell burnt wood, you should quickly reduce the speed.

Roller cutter for ceramics and glass

Working with materials such as glazed ceramic tiles or glass requires special care and attention. First, you need to make the outline of the required hole on the surface using a forma-y cutter, after which the hole is selected with a roller cutter, the head of which is made in the form of a ball.

Precautions when working with cutters

Since working with burrs occurs when using a tool whose speed is too high, there is a risk of injury from flying particles of the material being processed.

And most often the object of injury is the worker’s eyes. Therefore, special glasses are required. Glasses should be chosen that will maximally protect the eyes of a working person from any solid particles, as evidenced by their special markings.

Cone manufacturers

Burrs today are produced by many companies and enterprises, both in our country and abroad. It is possible to order burrs according to an individual drawing. Since the scope of such a tool is large, it is not always possible to find the required analogue on sale.

Domestic manufacturers

Among the domestic manufacturers, we can note such enterprises producing cutters as:

• Geomash, which produces burrs with a diameter from 76 to 490 mm.
• "Praktika", producing diamond-coated roller bits.
• Delo Tekhniki is a Russian manufacturer of metalworking tools.
• "Zubr" - produces rollers with abrasive heads.
• Burintech mainly produces powerful cutters for drilling wells of various types (oil, mining, gas).

Foreign manufacturers

Among the most popular foreign products are products for grinding and other plumbing work from companies such as:

• German Karnasch.
• Chinese Sturm, producing diamond-coated cutters. Although the brand itself was developed in Germany.
• Kraftool I/E GmbH, of German origin, whose products are sold under the STAYER brand.
• GROSS, also of German origin. Appeared on the market since 2008.
• Dremel is an American company that produces silicon carbide burrs.
• Norton company, which produces cutters with abrasive and diamond coating.

Whatever manufacturer you choose, do not forget that you may always need more than one cutter, so it makes sense to purchase sets of these devices so that each individual case has its own burr.

Metal cutters, burrs or milling heads: subtleties of choice and features of work. Articles from the company "Instrument - 24"

June 6, 2019

Let's take a closer look:

Cone or burr? If you have to process metal products, process welds or flaring, then you can’t do without burrs or cutters, but in essence they are the same tool.

They are often used in tandem with an electric drill or on a stationary machine if it is necessary to process a large part.

Such a tool will be an ideal solution during engraving and grinding work, when cleaning surfaces, boring holes and in a number of other operations. 

Design Features

Despite the fact that such a tool has been used for decades, it is constantly being modernized to make the work better and more accurate. At this time, the design of such a device did not undergo any significant changes.

As before, burrs consist of two components: a shank for mounting in a chuck and a cutting part, which directly processes the part.

Regardless of the type of burr, to carry out the technological operation, you need to use tools that can provide rotation up to 60 thousand revolutions per minute.

The use of a roller cutter and hand tools makes it possible to grind and process hard-to-reach surfaces.

Features of choosing a burr

To choose the right cutter, you need to take into account several basic parameters:• type of processing;• material properties of the part being processed;• dimensions of the part;

• area of ​​use.

Where are burrs used?

The carbide cutter has great functionality. They are widely used in many industries: electronics, machine tools, automobile manufacturing, jewelry processing, printing.

 

It is important that the miniature dimensions of the working part of the tool make it possible to process the surfaces of complex parts, for example, matrices.

A certain type of cutter makes it possible to perform other technically complex operations: grinding hard-to-reach holes, drawing beautiful patterns, making inscriptions, processing deep and complex grooves. 

In everyday conditions, a metal cutter helps home craftsmen carry out a whole host of different operations. A burr installed in an electric drill chuck makes it possible to carry out: boring holes, cleaning welding seams, grinding a metal surface, removing burrs, leveling the surface of a part, etc.

Classification of burrs

Considering that milling sharpening has several varieties, they are divided according to design:

• single-cone; • double-cone;

• three-cone.

The choice of milling head directly depends on what technological tasks the designer faces. According to its appearance, the cutting part of the cutter is divided into the following categories:

• conical;• round;• cylindrical;• oval;

• semi-oval.

To perform a certain technological task, you need to select a certain shape of the cutting part. For example, to engrave, you need a conical head. The grinding procedure requires a cylindrical head. If you want to choose a router for cleaning welds, and when working with flat surfaces, you need a round shape.  

Materials for making burrs

During the manufacture of burrs, electrocorundum, carbon steel, diamond chips and carbide are used. Milling cutters made of carbon steel are the cheapest option, which has a fairly short working life. Typically used for one-time work that is not very intensive. This tool is quite effective when processing soft metal is necessary.

Professional tools include diamond-ground burrs. They process very durable materials without any problems. The cutting part of such a tool can have any configuration and size. The tool bores without problems and also fine grinds deep holes. At this time, the surface becomes extremely smooth. Diamond-based burrs are equipped with various engraving units.

Among the entire range, it is carbide metal burrs that are distinguished by their long service life. They are actively used in factories and factories.

If you install such cutters on drills with high speeds, you can easily process the hardest materials: stainless steel, cast iron, heat-resistant steel, titanium.

Carbide burrs allow for fitting metal forms, as well as finishing the metal surface. Depending on the type of sharpening, such tools are divided into fine cutting, universal, ultra-thin, and for processing aluminum.

Tips for using a burr

If you want to increase the operating time of a burr for metal processing, you need to follow several rules:

• if you are processing metal surfaces, the working part must be in full contact with the workpiece; • the shank should not touch the workpiece, otherwise the burrs may become unusable; • when processing surfaces, it is necessary to avoid strong pressure on the tool, because

this can cause overheating of the cutter and breakage;• the use of the tool should be carried out exclusively on equipment with a high level of revolutions, which will prevent the tool from jamming in the metal - this guarantees more thorough processing of the surface of the grooves;• it is necessary to use a special lubricant that will improve sliding and reduce pressure and prevent severe wear of the working head device; • the level of wear of the cutting head can be minimized using a special suspension, which includes synthetic machine oil - it must be constantly lubricated with a similar composition;

• under no circumstances start work with a worn-out tool, because it will be necessary to expend a lot of physical effort, during which time the cutter itself, as well as the equipment used, may become unusable.  

And, of course, we must not forget about safety. After all, during work a large amount of small chips are formed, which fly in different directions. Therefore, before you start work, be sure to protect yourself: special glasses must be worn on your eyes, gloves must be on your hands, and a protective mask must cover your mouth.

Metal cutter, cone cutter for drill, ball type of emery

When finishing the surfaces of products made of different materials, special tools are used: a cutter, an abrasive wheel, a file, a metal roller, also known as a burr, emery and a roller bit. Depending on the type, the device can be installed in the chuck of an electric drill, screwdriver or machine tool.

What is a cutter

The tool is a device consisting of a shank, a rod and a head with notches, abrasive or diamond coating. The device helps solve problems related to processing and grinding surfaces in hard-to-reach places. The tool is used in equipment for crushing stone, broken ceramics, and concrete coatings. The rotation speed of the working part of the device is about 60 thousand rpm.

Modern manufacturers produce metal cutters for drills with different shapes, geometric parameters, characteristics and dimensions of the working head. Tools for wood, metal, glass and ceramics have found application in various fields of human activity:

1. medicine;
2. dentistry;
3. construction;
4. mechanical engineering;
5. mining industry;
6. jewelry making;
7. interior design;
8. furniture production.

Using a roller cutter you can create highly artistic works of art from bone, glass, metal, wood, ceramics and natural stone. Without a unique tool, it is impossible to produce metal-plastic window and entrance structures.

Areas of application

As a component for machine tools and hand-held electric tools, a roller bit with a large-diameter head is actively used for crushing stones with teeth made of hard alloy metal. A ball cutter for jewelry purposes is small in size and is used for processing small parts, applying inscriptions or patterns on jewelry, gift sets, and souvenirs.

Roller cutter for metal drill: types of tools, how to choose and use

When processing workpieces, it may be impossible to use an abrasive wheel, cutter or file. In this case, a so-called cutter or burr is used.

Devices installed in an ordinary electric drill do an excellent job of grinding and cleaning surfaces. In addition, cutters are also used for crushing various materials.

A roller cutter for a metal drill (cone bit, burr) is a device that appeared quite a long time ago. It consists of two parts: a fixing tail and a working element. The cutter can rotate at speeds of up to 60,000 rpm during operation.

Manufacturers today offer devices made of different materials and with working elements of various shapes and dimensions. Such a wide selection makes it possible to select devices for many technological tasks. When choosing, as a rule, they are guided by the parameters of the material that was used to create the tool being processed, as well as geometric characteristics.

Burrs are used in many areas, which include construction, mining, mechanical engineering, jewelry, medicine, etc. Using this device, you can effectively and efficiently process products not only from metal alloys, but also from glass, stone, wood, etc. plastics.

Roller cutters are also used in the manufacture of PVC windows . At mining enterprises, devices for stone of increased diameter and a working element with teeth made of hard alloy are used. Jewelers use these products to produce decorative parts and apply patterns and inscriptions to products.

Dentistry is another area where cutters are often used. This device is the main component of the famous drill. At home, burrs are installed in ordinary electric drills. Using them, home craftsmen solve a large number of household problems.

Using burrs, you can make a neat and even hole in ceramics, glass, brick, stone and wood products, make a good cleanup of welding seams and process hard-to-reach areas.

Types of burrs

Burrs can have different designs and include various materials. The following structures of metal sharashkas are distinguished:

• single cone;
• double-cone;
• three-cone.

The shape of the working elements also differs. So, there are devices with an oval, spherical, cylindrical or conical head. The choice of a suitable cutter depends on the configuration of the workpiece and the tasks assigned to the tool.

Roller cutters also differ in the material used for their production. Here it is worth highlighting:

• carbon steel alloy fixtures;
• diamond-coated cutters;
• abrasive burrs;
• hard alloy cutters.

Carbon steel

The tool, made of carbon steel alloy, is used in combination with a screwdriver or electric drill. Its main advantage is its low cost.

Using this tool, you can create complex recesses, remove sharp edges from products, create neat and high-quality holes, and also expand the diameter of already created ones.

Diamond coated

These devices are professional. These cutters allow fine boring and grinding of drilled holes. This type of tool is effective when processing ceramics and glass , and when working with high-strength materials.

Engraving equipment is equipped with diamond-type cutters, which allows for the finest processing and application of inscriptions and patterns on various coatings.

Abrasive tool

Such devices are similar to diamond cutters. Due to the increased hardness of the working element, the abrasive burr is used for processing glass, ceramics, plastics, stone, metal, etc.

These cutters have an abrasive working element, which is made entirely of abrasive material or made by spraying. An abrasive roller bit is characterized by a low price, but is much less durable than a metal tool.

With carbide head

This tool is often used in production. Carbide-type cutters are used for processing high-hard materials such as cast iron, steel, titanium, etc.

This type of jig is also great for processing weld seams.

In order to use cutters as effectively as possible, you need to consider several key points:

• the nature of the work to be done;
• properties of the material from which the workpiece is made;
• dimensions of the element to be processed.

It is also necessary to take into account the characteristics of the electric tool in which the burr will be placed. Here you should highlight power and speed.

Another important parameter of a metal processing tool is the type of cutting and the configuration of the cutting teeth. Based on these characteristics, the following types of devices are distinguished:

• with the finest cuts;
• with universal cutting option;
• with ultra-thin cutting;
• for processing aluminum alloys.

The highest level of performance is demonstrated by a tool whose head is double sharpened. Experts advise immediately buying a set of metal cutters. Having such a set of devices at your disposal, you will cope with all the necessary tasks.

How to use it correctly?

Several decades ago, burrs were used to work in combination with hand-held tools. Subsequent technological development contributed to the fact that manufacturers of this type of product began to equip stationary equipment with cutters.

Despite the fact that work using burrs in hand-held electric tools is characterized by a high degree of efficiency, with such processing it is impossible to obtain perfectly smooth and high-quality surfaces. In addition, the use of such a chisel in conjunction with a hand tool has an adverse effect on the tool itself, whose cutting edges become dull.

Installing burrs on modern CNC machines allows you to increase the durability of the tool, the accuracy and quality of processing.

But, if you follow some rules for working with burrs in hand-held power tools, you can ensure that the tool will last a long time and effectively. So, you need to remember the following:

1. The burr head must interact tightly with the plane being processed. You must also carefully ensure that the tail of the cutter does not touch the surface being processed, because this can deform the part.
2. When working, you do not need to press hard on the device, otherwise it will negatively affect the quality of the processing or cause overheating of the tool.
3. It is also important to choose the appropriate speed mode. This will give you the opportunity to save on electrical energy and extend the life of your drill.
4. The head of the device is subject to intense abrasion and wear. There are several simple techniques that can reduce the level of wear on this part and increase the durability of the tool itself. For this purpose, you can use a special lubricant, which reduces the degree of load and allows the tool to slide better over the product.
5. At the first signs of wear, it is advisable to change the tool immediately. Operating a significantly worn cutter can lead to tool failure.

Using a burr on a screwdriver or electric drill, you can process a wide variety of materials. But here it is important to follow a number of rules.

When working with a tool on stone or porcelain stoneware, you need to constantly moisten the surface being processed with water. Liquid should not come into contact with the electric tool, otherwise it may break.

Using cutters you can process not only natural wood, but also MDF, plywood, chipboard and fiberboard. A characteristic feature of a wood burr is a fairly large notch on the working element. If during processing you begin to smell something burning, you should set the power tool to a lower speed.

When working with ceramic tiles or glass with a roller cutter, be extremely careful and attentive. When processing such workpieces, it is necessary to pre-draw the outline of the hole on their surface using a special cutter. Then the hole is punched with a burr with a spherical working element.

When using an electric tool with a cutter, you must not forget about precautions and safety measures. Protect your hands and eyes from particles by wearing gloves and goggles.

Roller cutter for metal

When milling surfaces, there are times when conventional cutters cannot be used for one reason or another. Then many workers use a regular file, but this is not always effective, because it has minimal impact on some metals. In cases where it is not possible to use a cutter, file or even a grinding wheel, it is recommended to use a special tool, which is an attachment called a cutter.

Metal cutters

What is a cutter and its use

People have been using and knowing what a cutter is for a long time. There are no reliable sources when and by whom it was created, but the first mentions of its prototypes were several centuries ago. The metal cutter has a simple design: it has a shank and a working head. The first is necessary for securing it in the chuck of a machine tool or drill, and the head grinds the metal surface.

Nowadays, a large assortment of cutters has been created, the heads of which are designed for specific purposes. Their geometric parameters differ significantly from each other and allow them to solve a highly specialized problem. We list the most common areas of application:

• mechanical engineering;
• construction;
• mining industry;
• medicine;
• jewelry making.

Application of the cutter

In the construction industry, cutters are used to process metal, stone, wood, plastic and glass. For example, when making PVC windows, the joints into which the cutter cannot fit are cleaned. In mining, they are used in drills.

In the jewelry industry, cutters allow you to engrave inscriptions and patterns, drawings, and also use them to process the surfaces and corners of precious metals and stones. In medicine, cutters are most popular among dentists because they play a major role in the drill.

In everyday life, a metal cutter is used for a drill, which is simply attached to the chuck and makes minor repairs at home and in the country easier.

Thanks to the right choice of shape and material of a metal cutter, you can drill a hole, remove irregularities at the joints of products, sand seams and process places that cannot be reached with another tool.

Types of tools and design features

According to the material used in the design, the types of metal cutters come from:

• carbon steel;
• diamond;
• abrasive;
• carbide.

Carbon steel is used in cutters, which are used in working with an electric drill. With their help, you can process wood and metal products, round corners, drill new holes and bore old ones. Its main advantage over other types of burrs is its low price.

Diamond cutters for metal are more often used in production, but they can also be found in the kit of a craftsman who does repairs. In addition to professional equipment, they are also suitable for electric drills. The working surface of such a cutter is coated with diamond coating. This allows you to grind and bore holes. Used for processing both brittle and hard materials.

Abrasive cutters

In terms of manufacturing technology and scope of application, an abrasive cutter is similar to a diamond cutter. Electrocorundum is often used instead of diamond chips. The short service life is compensated by the low cost.

Carbide cutters are used in production in powerful machines that allow rotation speeds of up to 60,000 rpm. They are used to process high-hardness steels and alloys, cast iron, titanium and much more. The use of carbide burrs allows for the best processing of welded seams.

The stores offer a variety of sets of metal cutters, which differ in head shape:

• cylinder;
• sphere;
• oval;
• parabola;
• tongue of flame;
• countersink.

The cylindrical shape allows you to bore holes (including blind ones), machine ends and internal corners. The end of such a cutter can be spherical or smooth. The first option will not allow you to do some operations, but it will be possible to use it instead of a sphere and save money on it. If the burr is coated with diamond or abrasive coating, then it can be used to sharpen the tool.

Diamond cutter

The spherical head is used for smoothing product edges, internal corners and welds, sharpening, grinding and much more. The oval shape of the head gives it versatility and gives it the capabilities of both cylindrical and spherical heads. When processing internal surfaces with such a cutter, there will be no deep groove left. Very often used in the automotive industry and auto tuning when processing engines and manifolds.

The parabolic contour can be sharp or rounded. In the first version, this will allow you to easily remove burrs in gear parts. The rounded shape allows you to make small grooves and process internal welds.

The most common type of burr is a flame-shaped attachment. It is universal and suitable for most operations, even on the most difficult surfaces and materials.

G-Cut cutter shape countersink

A countersink is a special cutter that is used to chamfer a hole. This can be done with a drill with a large diameter, but a countersink allows you to make a more even surface and angle of inclination.

How to choose the right cutter

High performance of a burr depends on several factors, such as:

• the operations that will be carried out by it;
• workpiece or product material;
• size and shape of the object being processed.

It is necessary to choose cutters for a drill, guided by the power and rotation speed of this power tool.

Another important factor when choosing a burr is how the cutter teeth will be cut into metal. Teeth cutting can be:

• thin;
• universal;
• ultra-thin;
• for working with aluminum.

Non-ferrous metals can be processed with carbide cutters. Soft metal is easy to machine if a hardened tooth grind is used. Diamond and abrasive burrs are highly productive and can easily process hard materials. Double sharpening of the tool head increases productivity. Ultra-fine cutting allows you to grind surfaces.

Experienced craftsmen immediately buy large sets of cutters. This allows them to always have all types and forms of this tool available and cope with their favorite work situations.

How to use burrs correctly

Most often we see the use of cutters for a drill or with other hand tools, because this option is very effective. But it also has disadvantages, for example, it is not possible to make an even hole with high precision, and frequent displacements and vibrations quickly wear out the burrs.

Drill bits

Today, cutters are increasingly used in production, for example, in CNC machines for processing metal surfaces of workpieces in combination with other cutting tools. Thanks to the rigidly fixed position, it is possible to achieve increased processing accuracy.

We present a list of rules for the proper use of burrs:

1. The cutter head and the surface being machined must be in full contact.
2. The shank should not come into contact with the machining area, otherwise it may lead to tool breakage.
3. The rotation speed should be correctly selected in accordance with the type of cutter and the material of the workpiece being processed. This will increase the durability of the cutter, reduce electricity costs and reduce the likelihood of unplanned deformations.
4. To extend the life of a burr, tool head wear should be monitored and reduced. To do this, it is necessary to use a lubricant based on machine oil during operation.
5. It is necessary to regularly check the wear level and promptly replace the burr with a new one.

Thanks to the cutters, finishing and grinding operations are carried out; in addition, they allow you to make engravings, holes and grooves in those places and with those materials that other tools cannot handle. Depending on the tasks, you should select a burr according to the situation.

What is a cutter

Roller cutters or burrs have been used by humans for decades, and perhaps the history of this tool goes back hundreds of years. There are no sources on this matter. This invention of the human mind is a special attachment made of various metals, with the help of which cleaning, grinding, surfaces, and crushing of materials are carried out.

What is a metal cutter - Metalworker's Handbook

A burr is a universal metal-cutting tool designed for high-speed finishing of surfaces, holes and grooves of complex shapes. There are burrs for wood, stone, and glass, but carbide burrs for metal have the greatest technological capabilities.

Material and design

The burr is a composite tool: the working part is attached by soldering to a cylindrical shank made of medium-carbon alloy steel type 30KhGSA. She may be:

1. Made of tool carbon steel (U10A, U12A), often intended for drilling. The durability of such a tool is low, so it is used when processing relatively soft materials. For example, with such a burr on an engraver you can create designs of tiles or ceramic cups. The second option is that such work is rare in the household, which makes purchasing an expensive cutter impractical.
2. Made of high-speed steel type R6M5. The tool will cost more, but the possibilities of its use are significantly expanded. The high red resistance of high-speed steels makes it possible to effectively process almost all grades of carbon and medium-alloy steels. At the same time, the thermal deformation of the working part is insignificant, which has a positive effect on the accuracy of the work.
3. Carbide burrs, the working part of which is made of metal-ceramic type VK25 or VK30 (also found in tungsten-free carbide alloys or mineral ceramics). This tool can be used to grind high-strength heat-resistant and stainless steels, as well as cast iron.
4. Extra-resistant burrs with diamond-coated working edges. They are a professional tool and are used in large-scale operations of this kind. They differ in maximum cost.

The equipment in question can be used on any equipment that is equipped with a rotating working head, and the chuck is capable of reliably securing the burr shank (the diameter of the tail part is most often standard: 6 or 8 mm, although engraving cutters have smaller sizes). Such equipment includes a high-speed electric drill, as well as a high-speed grinding or drilling machine.

The only condition is that the burr is not a power tool, but a dynamic tool, and is adapted for use with a spindle speed of at least 6000065000 min-1.

Profiles of the working part of burrs

Depending on the nature of the work performed, the working part may have the following configuration:

• Cylindrical, designed for processing flat surfaces or fine deburring. If there is a rounding at the end, the tool can process the corresponding radius transitions;
• Conical, with the help of which the final shape is given to grooves or fillet grooves;
• Spherical, which is used to clean and fine-tune the seats for bearings, bushings and other parts with a cylindrical generatrix;
• A reverse cone, with which it is convenient to process undercuts (in such cases, the use of a mobile tool like an electric drill is especially justified);
• Special shapes - parabolic, oval, truncated cone, etc. - for carrying out work along specific trajectories.

Experts have systematized recommendations that relate not only to the shapes of metal surfaces processed by burrs, but also to the materials from which the part is made. These recommendations relate to the shape of the cutting elements, which are always present on the working part of the cutter. They can be:

• Pyramidal in cross-section. Used for mass work with all steels and alloys, with the exception of aluminum;
• Small-belt, used for processing products made of ferrous metals and alloys, as well as carbon fiber;
• Large-belt, used when working with aluminum and zinc;
• Triangular: used for the same purposes as pyramidal, but are less durable.

  How to weld metal with an inverter

The type of cut on the working part of the burr determines the performance and wear resistance of the tool. With an increase in the contact area of ​​the notches with the surface of the part, and with an increase in the cutting speed, diamond burrs and high-speed steel burrs will have the highest durability.

Tape notches are distinguished by a gradual increase in force and a virtual absence of shock loads at the initial moment. That is why the use of such notches relative to metal and mineral ceramics provides increased resistance to carbide cutters. Diamond burrs behave similarly.

Sizing and operation

GOST R 52870-2007, which regulates the production of domestic tools, establishes the following markings. Let's look at an example:

Burr A 16 25 C 8 30. Marking and classification elements mean:

• The first letter is the type of working part (A - cylindrical, C - spherocylindrical, D - spherical, E - oval, F - spheroconic, G - spheroconic with a pointed tip, H - special shape, J, K, L, M, N - various design options for the conical part).
• The second number is the diameter of the cutting part in mm.
• The third number is the length of the working part in mm.
• The second letter is the type of notch on the working part (F - small, M - medium, C - large).
• The fourth number is the diameter of the shank in mm.
• The fifth number is the length of the shank in mm.

GOST must be indicated at the end of the designation.

To make the right choice, you need to know the nature of the work being performed, the cutting accuracy, and the nominal speed for which the purchased metal burr is designed.

For example, a carbide cutter for an engraver with a relatively low speed (less than 40,000 min-1) can contribute to periodic temperature fluctuations in the body of the working part.

This may negatively affect the strength of the solder connection between the working part and the shank, or rapid chipping of the cutting edges. It is worth remembering that if a tooth becomes dull, the instrument cannot be restored or sharpened.

When engraving, burrs with a conical working part will be in demand, when boring or grinding - conical burrs with an approach angle of 6090º, and when deburring - cylindrical burrs.

Diamond burrs provide the best surface cleanliness, but for their successful use it is necessary to ensure a minimum processing allowance - no more than 0.10-12 microns. The same requirements apply to engraving operations that are performed using the type of tool in question.

During continuous operation, the working part of the equipment must be constantly cooled. To do this, the tool is periodically dipped in high-viscosity oil, or the working part is immersed in synthetic wax.

A common mistake is to apply significant force to the burr. Firstly, a bending moment occurs at the soldering point, which will accelerate fracture at the junction of two dissimilar materials.

  What is anodized metal?

Secondly, the processing force and temperature at the contact point will increase sharply (this does not apply only to burrs made of high-speed steel).

Equipment with worn notches should be immediately replaced with new ones, since burrs are often sold in whole sets.

Types of metal cutters for drills

When processing metal surfaces, very often tools such as a milling cutter, grinder wheel or file cannot be used. An alternative replacement for a file is a metal cutter when used in a drill. This product allows you to cope with such technological tasks as stripping, grinding, and even crushing metal materials.

What are cutters and what are they for?

A cutter is also called a burr, which is a tool consisting of a shank and a working area.

The shank serves to secure the product in the drill chuck, and the work area carries out the direct work of grinding various types of materials. Burrs are used in special tools where the shaft rotation speed reaches 60 thousand revolutions per minute.

The drill is not capable of producing such a rotation speed, so it is worth noting right away that the use of burrs in this tool is not always rational.

Modern manufacturers of such attachments make them from various materials, which allows not only to increase the functionality of the products, but also to extend their service life. In addition, roller cones are available in different shapes and sizes. This is done to ensure that a specific product shape is selected for each specific case.

Interesting to know! Roller cutters find their application in such areas as construction, mechanical engineering, automotive, mining, as well as jewelry and even medicine (in particular dentistry).

There is a need to use burrs at home as well. This issue is especially relevant for those who prefer to work with metal. In addition to processing metal surfaces, cutters also allow for effective processing of wood, glass, stone and plastic.

Roller cutters allow you to obtain neat and smooth surfaces to be processed in metal, but for this you must correctly select the required shape of the product. To obtain maximum precision and accuracy, work should be performed on special machines (drills). Using drills, it is usually possible to carry out only rough finishing of materials.

What are there

Roller cutters are produced in different types and shapes, and a wide variety of metals are used for their manufacture. According to their structure they can be divided into the following types:

• Single cone.
• Double-cone.
• Three-cone.

According to the shape of the head, the products in question are spherical, oval, conical, cylindrical and semi-oval. Which cutter to choose for the job depends on the assigned technological tasks. Based on the material used, burrs are divided into different types. These include:

1. Carbon steel cutters. If carbon steel is used to make a burr, then such products are intended primarily for working with a drill or screwdriver. Such burrs are used both for boring wood and metal products. A positive feature is their relatively low cost, which allows you to always have a whole set of cutters in your home arsenal.
2. Metal cutters with diamond coating. Diamond burrs are classified as professional, but can also be used with an electric drill. Such products allow for fine grinding and boring of holes. Diamond burrs are more effective not only in working with glass and ceramics, but also with metal materials. In addition, the surface treated with a diamond cutter has a minimal level of roughness, unlike products made of carbon steel.
3. Abrasive cutter for metal. It has significant similarities with diamond burrs, only abrasives are used instead of diamond coating. Abrasive burrs are highly durable, so this type of product can be used for both metal and other types of materials. Abrasive products can be manufactured in two ways: by spraying the work area, or entirely from abrasive.
4. Hard alloy cutters. Such cutters are often used in production environments, so it is not recommended to use them for hand-held power tools. They have a long service life and therefore have a high cost.

Now it’s clear which cutter is intended for what. For home use, a carbon steel conical burr is most often used. And to carry out work in hard-to-reach places, abrasive burrs are used.

Rules for using cutters for drills

To increase the service life of hand-held power tools when carrying out work using cutters, there are the following recommendations:

1. When performing manipulations with a burr, do not allow the workpiece to come into contact with the shank of the nozzle. Upon contact, the shank overheats, which entails destruction of integrity.
2. Do not put too much pressure on the burr head. With increased load, a decrease in processing speed cannot be ruled out. When a tool overheats, its service life decreases.
3. Replace worn out rollers in a timely manner. Working with a worn-out attachment has a negative impact on both the workpiece itself and the power tool.
4. The nozzle should be periodically dipped in a special lubricant.

In conclusion, it should be noted that the cutter is an excellent tool that can significantly expand the functionality of the drill. It is also worth remembering that you should not get carried away with processing metal surfaces with cutters, as this will negatively affect the operating time of the electric drill.
