How to choose an engraver
An engraver is a multifunctional tool powered by electric current and designed for precision processing of wood, metal, glass and other materials. There are many types of such instruments on the modern market, differing in their design, purpose and dimensions. This article discusses the advantages and disadvantages of this or that type of engraver and provides criteria for choosing a product.
What is an engraver?
The operating principle of the engraver is based on the rotational energy of the shaft connected to the drive part of the electric motor. The appearance of the part may differ from one manufacturer to another, but the components are almost identical. The engraver consists of the following elements:
- The handle body is the main part in which the entire drive part and electric motor are located. In household products, the handle is made of plastic, but in the industrial version there is a metal body coated with rubber for convenience.
- Electric motor of varying power, depending on the purpose of the device, it can be 6,12,24 or 220 volts. The entire operation of the product is based on the rotation of a power unit powered by electric current; if the engine fails, the use of the tool will not be possible.
- On the body of the part there are controls in the form of a current switch and a voltage regulator. With their help, you can turn the device on and off, as well as adjust the number of revolutions of the drive shaft.
- The drive shaft is located at the end of the engraver and is connected to the power unit.
- Spindle with collar. A nozzle is attached to this element, which is secured with a crimp collar and securely fixed to the drive shaft. During rotation of the motor rod, the drive acts on the tip of the nozzle and sets the movable part of the tip in motion.
- Inside the tip there is a collet chuck, which holds the nozzle on the engraver and ensures stable rotation of the rod.
Depending on the purpose of the device, there are many attachments for a particular job, differing in material, diameter and rotation speed.
Areas of application of the engraver and its types
Wood cutting Sanding parts Trimming various materials
The engraver is a multidisciplinary tool; it can be used for the following work:
- For carving and milling metal, wood, glass or concrete. To perform such tasks, nozzles with abrasive coating or special sharpening are installed, which allow you to process even the hardest material.
- Sanding stone, plastic, glass or wood. Most often, this work is carried out in hard-to-reach places or on small parts where it is not possible to use a large tool.
- The engraver is often used for cleaning and polishing various surfaces, such as glass, plexiglass, metal, and ceramics. To perform these works, nozzles with hard or soft wire and polishing felt are used.
- Recently, it has become popular to use the engraver as a polishing machine for processing jewelry. Such actions give the jewelry its original shine and remove scratches or cracks in the metal.
- It is also possible to use an engraver to work on ceramic tiles and granite in order to bring them to the required size.
Depending on the purpose and power, this device is divided into several types:
- With built-in battery. This tool is considered a household tool and is not suitable for use for industrial purposes. Charging is carried out from the general network using a special charger. The battery capacity may vary; the operating time and rotation speed of the product depend on it. The main advantage of such a product is its mobility and independence from the presence of an electrical network, but it also has a significant drawback: the battery has a limited service life.
- Operating from a 220 Volt network. This is a semi-industrial version of the tool, which has more power and, therefore, can be used continuously for a long time.
- Engravers also differ in their drive mechanism, which can be flexible or rigid. The principle of operation is the same for both, the difference lies in the moving part of the shaft, which can be bent 90 degrees relative to the body of the device.
Also, many manufacturers produce engravers in a set with many attachments for processing various materials. Such universal tools included in the kit are very popular among both household users and qualified specialists.
Criterias of choice
When choosing the type of engraver, you need to pay attention to several technical indicators. First of all, it is worth deciding on the tasks that will be solved using the engraver. For example, if a tool is used for grinding and polishing at home, then there is no need to purchase an expensive tool with a whole set of attachments; it will be enough to buy a household appliance with several additional elements.
It is also important to consider access to the electrical network at the workplace, since it is not always possible to use current as a power source. In such cases, it would be advisable to use an engraver with a built-in storage battery, but it is worth paying attention that the capacity and power of the battery corresponded to the tasks being performed.
The technical characteristics of each tool indicate the number of revolutions of the rod per minute and the weight of the product as a whole. These parameters must be taken into account, since working with an engraver that is heavy for a long time will be problematic and a device with low shaft speeds may overheat during prolonged use, which will lead to breakdown.
Selection of attachments for engraving work
After determining the tasks that will be solved using the engraver, you need to select the type of attachment suitable for the work.
For sanding soft materials, such as wood or plastic, attachments with medium or low hardness stones are used. Such a device will level the surface when rotating, and will not wear off. To level the product in hard-to-reach places, corners or internal surfaces, nozzles come in various shapes and thicknesses.
Carving and milling are carried out with a sharpened steel tip. Such an element is made in the form of a cone-shaped cutter with a spiral thread, which, when rotated, removes part of the processed material to the required size. These bits require periodic sharpening and lubrication, otherwise they may become susceptible to rust and corrosion.
Cleaning and polishing of various surfaces is carried out with a tip with a rigid wire, which is attached from the center of the nozzle to its edges. When the drive rotates, the steel thread cuts into the surface being treated and cleans it of plaque, old paint or rust. For different materials, there is a nozzle with different levels of rigidity; the softer the surface, the more flexible the wire at the tip will be.

What is an engraver and what can it do?
An engraver is a tool necessary for use in any household.
The range of its applications is so wide that after reading this article you will definitely want to purchase it.
So, what is an “engraver”?
The engraver consists of a plastic case, inside of which there is a rotating shaft powered by electricity.
The operating principle is extremely simple. Each engraver, regardless of price and country of origin, is powered by a small motor installed inside the body, which drives the shaft of the device.
But it is to the shaft that attachments are attached, allowing the engraver to be used for various purposes.
It is about determining which attachments are needed for specific jobs that will be discussed below.
If you decide to engage in carving and milling of stone, wood or metal products, then you need attachments that have wire brushes at the end, sharp cone-shaped attachments, or, conversely, rounded ones.
You should purchase consumables immediately when purchasing a tool for the appropriate purpose, since manufacturers have not come to a unified standard for the types and types of materials for engravers, and having purchased a tool from one brand, you may sometimes not find a material suitable specifically for this engraver.
For grinding, as in a grinding machine, abrasive wheels are suitable. The method of application depends on the density of the abrasive materials.
The purpose is the same as that of a tool specifically specialized for this - a grinding machine.
In order to clean or polish a metal, stone or wooden surface, it is worth purchasing discs and brushes of different types, which will mainly differ in the number of hairs used in them.
In most cases, most of these attachments are already supplied with the engraver, however, it is worth checking when purchasing whether the necessary material is available specifically for your purposes.
What are the tool selection options? It's quite simple
Power and rotation speed. Both the cost of the tool and the quality of the work performed depend on these indicators.
A very important point will be the ability to regulate the speed of rotation of the roller, as well as the power supplied.
The last parameter, by the way, is quite rare.
We hope that these tips will help you choose an engraver that is suitable for your tasks!

Engraver (drill). Types and work. Application and how to choose
An electric engraver, or drill, is a compact tool designed for engraving and fine processing of various materials. This equipment is produced by both branded European manufacturers and little-known Chinese brands. In this regard, the range presented on the market differs in price and quality. Engravers come in different sizes and power, so you can choose the optimal equipment to perform the amount of work you are interested in.
What can an engraver do?
Hand engravers are compact equipment that is used for precision machining. In this regard, it cannot be used to implement global tasks.
Engravers are equipped with various attachments, which makes it possible to use them for the following types of work:
- Grinding.
- Milling.
- Engraving.
- Cutting.
- Drilling.
- Polishing.
The device is compatible with small nozzles, so its use for construction or large-scale tasks is unacceptable. If you load the engraver, say for drilling thick-walled steel, the device will simply burn out.
The electric motor installed in it is not designed for heavy loads, so it can stop if the resistance of the material being processed is high.
Principle of operation
According to the principle of operation, engravers are similar to a conventional drill, grinder or screwdriver. They have a lightweight body in which an electric motor is installed. A collet is attached to its shaft, with the help of which the attachments for processing are fixed. The engine can transmit power with or without a gearbox. The tool has engine speed adjustment. Some models can rotate in both directions.
The vast majority of commercially available engravers provide rotating attachments, but there is a separate category of impact devices. Such a tool does not drill into the surface of the material, but hits it with a sharp tip of the nozzle. Such equipment is highly specialized. It is intended exclusively for engraving on hard surfaces. Since the spindle does not rotate, cutting, polishing or grinding workpieces with such equipment will not be possible.
According to the method of execution, hand engravers can be divided into several types:
- Regular network ones.
- Rechargeable.
- Hanging.
Conventional network engravers
A typical network engraver is a device that is held in the hand like a ballpoint pen. The tool is connected to the electrical network. This engraver can be supplied with a flexible shaft.
It is fixed in the main collet of the tool, and has a miniature chuck at its tip. Thus, you can place the drill on the table and hold only the tip of the flexible shaft in your hand, providing fine processing.
This allows you to reduce the strain on your hands if you are doing a large amount of work.
Often, low-price tools come with a flexible shaft, which quickly fails. When periodically bent, it breaks or jams. As a result, the electric motor inside the engraver body stops.
If it is not turned off in time, the tool may burn out. In this regard, even if you choose a cheap tool, you should avoid using the included flexible shafts.
The optimal solution would be to purchase a separate shaft produced by a name brand.
Electric engravers are available in various sizes. On sale you can even find miniature devices that have low power. They are very light and compact, but their performance is only sufficient for precision machining of soft materials. Such equipment is chosen for modeling.
Mobile cordless drills
Cordless engravers are more expensive than networked ones, but they are practically no different from them. Their only feature is that they have their own power source, so if the battery is charged, you can work anywhere without being tied to an outlet. To recharge the battery, the kit includes both a regular charger and an adapter for installation in the car's cigarette lighter.
There are even engravers on sale that run on regular AA batteries. Of course, their productivity is very low, but such tools have found their application. They are bought for polishing jewelry and other delicate and very light work. These Chinese engravers are the cheapest, and in most cases are useless, since they can only perform the simplest tasks.
Hanging engravers
The suspended type of engravers deserves special attention. They have a square or short cylindrical body that can be hung on a wall or countertop. From it comes a flexible shaft, similar to that used on conventional network devices.
A pedal is installed between the housing and the wire for connecting to the socket. It fits under the operator's feet.
When working with such a tool, you need to press the pedal with your foot, after which power is supplied to the electric motor, which rotates the nozzle installed in the collet on the shaft.
The pendant engraver is convenient because the flexible shaft is made of high quality, it is lightweight and fits comfortably in the hand. If the work is finished, you just need to release the pedal with your foot. This reduces operating noise. If you need to pause for a few seconds to review your results, you can easily turn off the tool, thereby stopping the noise.
Engraver selection criteria
The engraver is quite a popular tool, so it is not surprising that dozens of brands are engaged in its production. In this regard, there are many models on the market, which complicates the choice. If you want to purchase such a tool, you should be guided by the following criteria:
- Power.
- Number of revolutions.
- Weight.
- Noise level.
- Collet size.
The first criterion is power. It depends on it how productive the tool will be. If the engine is too weak, then any attachment in contact with the material being processed will reduce its speed, after which the shaft will stop completely. As a result, even the simplest tasks will take a long time to complete instead of just a few seconds.
For home use, you should choose equipment with a motor power in the range of 120-170 W.
A tool with such characteristics will not only be able to perform quick engraving, but, if necessary, will allow you to drill a small hole in the metal or trim some workpiece.
If an engraver is needed for a hobby, in particular for processing miniature wooden parts, modeling, then you can get by with a 35-50 W tool, although it is rather weak. The more powerful the tool, the better, but this increases the cost of the equipment.
As for the number of revolutions, for comfortable operation, devices with an engine rotation of over 20 thousand revolutions are usually chosen. Name brand tools, even with a 170 W motor, often produce up to 32 thousand revolutions, so the figure of 20 thousand is modest. The simplest hobby engravers can produce 6-8 thousand revolutions. Most of the tools on the market have smooth adjustment, which allows you to adjust the motor rotation from a safe minimum to maximum.
The tool that will be held in the hands should weigh between 500-750 grams. If you have the opportunity to purchase a powerful, but at the same time lightweight engraver, then you should give preference to it. A drill that is too heavy will quickly tire your hands, so if you need to work for a long time, it will not be suitable. If you plan to use a flexible shaft, then the weight criterion is not critical
When working in a residential area, you should give preference to low-noise devices. In addition to the noise that the electric motor creates when rotating, the sound of the nozzle rubbing against the surface of the material being processed is also added. If both sound sources are loud, then it will be unpleasant for other residents to be in the apartment or house. Even a noisy tool can be chosen for work in the workshop if the operator plans to use headphones to protect his hearing.
The last, but one of the most important criteria is the size of the collet. The names of its parameters determine which attachments can be clamped in the tool. The most common option is collets with a diameter of 3.2 mm.
They are most often used both in everyday life and in professional processing. It is ideal if the tool comes with several collets that can be installed on the spindle extending from the motor.
In addition to the 3.2 mm diameter, 2.4 mm, 1.6 mm and 0.8 mm collets are also common.
Engraver equipment
Engravers are sold in a specific configuration. The cheapest tool is simply offered in a cardboard box, and has nothing other than the engraver itself. Sometimes the basic set can be expanded, which is found in more expensive assortments. In this case, the package may include:
- Flexible shaft.
- Angle adapter.
- Hanging stand.
- Storage case.
- Box with nozzles.
- Spare graphite brushes for the engine.
- Templates with letters for engraving.
- Collets of various diameters.
Most often, the kit contains just an engraver with several attachments and collets. As for the angle adapter, stand and flexible shaft, they are less common. A plastic storage case is included with equipment in the higher price segment. It is worth noting that those attachments that can be found in the standard configuration leave much to be desired in terms of wear resistance. They wear out quickly, so you will soon need to buy new ones.

Electric engraver: device, principle of operation and choice of tool
The modern market offers a wide variety of technical devices that allow you to perform various technological operations. The most notable of these devices, both in terms of its functionality and compactness, is the engraver, designed for various types of processing of products from different materials.
In particular, using such equipment and the working attachments with which it is equipped, it is possible to successfully perform such types of processing as drilling, milling, engraving, cutting, deburring, grinding and polishing.
By equipping engravers with the appropriate working attachment, you can equally successfully use them for working on metal, wood, stone, glass and many other materials.
Wood carving with electric engraver
What is an engraving machine?
An electric engraver (its other names are “mini-drill”, “grower”, “drill”) is a device that looks like a massive fountain pen connected to an electric power supply or connected to an external electric motor with a flexible drive. The internal part of the design of such a device consists of the following elements:
- compact electric motor;
- an impeller, which is responsible for cooling the drive motor;
- gearbox;
- the shaft of the device, which is called a spindle.
Hand engraver design
All elements of the internal structure of the electric engraver are placed in a compact housing, on the surface of which there are special holes designed to remove heated air from the electric motor.
The body design of hand-held electric engravers is designed in such a way that it is convenient to manipulate them during processing. For this purpose, some models are equipped with removable handles.
To secure various working attachments that can be equipped with an engraver's tool, a special nut is provided in the upper part of the body. Electric engravers are controlled using several buttons, also mounted on its body:
- buttons to turn the device on and off;
- a button that blocks its engine;
- regulator, with the help of which the spindle rotation speed is set.
The flexible shaft is inserted into the engraver spindle and secured with a union nut on the threaded part of the body
The standard equipment of modern engraver models includes a wire through which the device is connected to the electrical network, as well as a ring used to hang the device on a special tripod. If users of mini drills and engravers want to make such devices more convenient to use, they can additionally equip them with flexible removable shafts.
A hand-held electric engraver, used in conjunction with a flexible shaft, allows you to successfully process hard-to-reach areas on any product. The most reputable manufacturers immediately include in the standard set of the device a flexible shaft for the engraver, on the mounting part of which working attachments of various types can be installed.
A flexible shaft equipped with an attachment for fixing the working tool allows you to make an engraver from a conventional drill, which in this case will act as a drive mechanism.
The telescopic stand is secured to the work table with a clamp and serves for convenient tool hanging
Operating principle of a typical electric engraver
The principle by which any engraver works is quite simple: the drive electric motor, through a shaft, transmits rotation to the working attachment, which imparts torque to the tool fixed in it. Many modern models of hand engravers are capable of providing tool rotation speeds in the range of 3–40 thousand rpm.
The functionality and versatility that modern engraving devices are characterized by is ensured by the variety of tools used with them.
The following tools are used to transform a compact engraving device into a multifunctional processing machine:
- drills with which the engraver is converted into a mini drill;
- milling cutters of various designs, allowing processing of flat and shaped surfaces, as well as holes, grooves and recesses of various configurations;
- disk tools used to perform cutting operations on thin metal and other materials;
- metal brushes, which are used to clean the treated surfaces from traces of corrosion and other contaminants;
- abrasive tools with working heads of round, semicircular, oval and cylindrical shapes, used for grinding and polishing the surfaces being processed;
- tools whose working head is made of felt (with their help, together with special pastes, polishing operations are performed);
- tools with a conical working head (a conical engraver is used to apply inscriptions and patterns to the surface of the workpiece).
Engraver as a small router
The tools for the engraving device differ from each other not only in design, but also in the material of manufacture. By choosing the right working tools, you can successfully process products made from different materials using an engraver. Such materials may include, but are not limited to, metal, wood, stone, bone, glass, ceramics and plastic.
Of course, you should not count on the fact that such a compact power tool will be able to cut a massive metal sheet or cope with other technological tasks that a more powerful stationary machine can solve. Such tasks are not set for this device: its main purpose is the processing of small-sized parts, as well as the decorative design of products made from different materials.
How to choose the right engraving device
The main question that should be resolved before purchasing an engraver is for what tasks and with what intensity such equipment will be used.
So, for not too intensive use and simple processing of various products in a home workshop, a cordless engraver that is not very powerful, as well as a simple engraver made from a conventional drill, are suitable.
To solve professional problems, you should choose the appropriate engraving equipment.
Let's consider the parameters that you should pay special attention to when choosing an engraver. Power
The power of the engraver can be in the range of 30–300 W. This parameter determines, first of all, the list of materials that the engraving device can handle. To perform simple work in a not too intensive mode, devices with a power in the range of 100–150 W are quite suitable, and for solving professional tasks you should choose engravers with a power of 175–300 W.
The engraver's 170 W power is sufficient for most engraving jobs, as well as cutting, deburring and polishing.
Weight
Powerful professional engravers are quite heavy, which makes working with them quite tedious. If you do not need to purchase an overly powerful and heavy device, it is better to choose a compact and lightweight battery-powered engraver or any other model whose weight does not exceed one kilogram.
Ergonomics
How comfortable it is to work with an engraving device is also influenced by the shape and size of its body. Is it convenient to hold the engraver in your hand, is its center of gravity located correctly - all this ultimately determines the accuracy of the processing performed.
The engraver should fit comfortably in your hand
Noise and vibration levels and heating levels
Reputable manufacturers of engraving equipment pay great attention not only to the technical characteristics of their products, but also to the issues of reducing noise levels, vibration, and protecting the device from overheating. Because of this, such engravers are quite expensive.
If we talk about engraver models in the lowest price category, then almost all of them overheat during operation, and do not make much noise, since they are not very powerful. Engravers belonging to the middle price category make noise, get hot, and vibrate quite a bit.
Manufacturers of such devices, while providing them with decent power, do not focus on the smaller shortcomings of the offered equipment.
Equipment
Almost all serial models of engravers are supplied with a set of working tools that allow you to use the device for various types of processing. Both the quantity and quality of the tools included in such a kit may vary.
This depends primarily on the engraver manufacturer and the specific model.
Meanwhile, you should keep in mind: even if the conical engraver is of very high quality, cutters, drills and any other tools included in such a kit are, in fact, consumables that will have to be constantly purchased in the future.
A rich set of engraving kits will give you the opportunity to try out the tool at work as much as possible.
Trademark
On the domestic market, engravers are represented by many models from different manufacturers. Such a variety of engraving devices offered allows everyone to choose them in full accordance with their needs and financial capabilities.
Meanwhile, when choosing a simple battery-powered engraver or a professional engraving machine, it is better to give preference to equipment from trusted manufacturers, which will not only last much longer than models from a little-known brand, but will also successfully cope with all the tasks assigned.
Among the manufacturers whose engraving equipment is deservedly popular among professionals and home craftsmen, we should note the companies Dremel, Hammer, Makita, Hitachi, Sturm, Bosch, Einhell. When choosing engravers of a certain brand, be guided not only by photos of such devices and their technical characteristics, but also by reviews of users who have already assessed their capabilities from their own experience.
Engraving machines using laser technology
To process products made from various materials, not only a metal cutter, drill, conical engraver or disk tool is used, but also a laser beam. Using such a beam, a laser engraver, often called a 3D printer (or volumetric printer), operates.
Using such a machine, which can be controlled not only manually, but also using a CNC system, various patterns and inscriptions, including three-dimensional ones, are made on the surface of the workpiece. By the way, a conventional conical engraver cannot cope with this.
A laser engraver, which may look like a floor-mounted CNC machine, a tabletop machine, or a hand-held device, can also be used to precisely cut thin-sheet material.
Small-sized desktop laser engraver model
Depending on the module that produces coherent radiation, a laser engraver may fall into one of the following categories:
- liquid-type lasers used to equip powerful industrial machines;
- laser diodes (modules of this type are used in desktop engraving devices).
Laser cuts in metal have perfectly straight edges
A universal engraving machine that performs processing using a laser beam has a number of advantages, including the following:
- The geometric parameters of the processed product, which is not subjected to mechanical stress, remain stable.
- The inscriptions and patterns applied using such a device are distinguished by high clarity and precision of execution, which is not always possible to achieve with a conventional conical engraver.
- Compared to conventional engraving devices, a laser engraver consumes 8–15 times less electricity.
- Since there are no rubbing parts in the design of a laser engraver, the working life of such equipment is significantly higher than that of conventional engraving devices.
- Desktop laser engravers, having a small weight and size, are highly mobile and do not take up much space during operation and storage.
- The use of CNC laser engravers allows you to easily, quickly and with a minimal budget organize mass production of products with decorative surface designs.

How to choose an electric engraver: tips and reviews about manufacturers
Engraving is a fairly popular trend in decoration. Convenient portable instruments are available on sale today, which open up many possibilities for amateurs. This applies to a mini drill, which is also called an electric engraver.
This unit is easy to use, so even people who are far from technology will be able to handle it. If you want to create jewelry, make your own souvenirs and gifts, then an electric engraver will be what you need.
How not to make a mistake in choosing
Electric engravers are also called mini drills. They are intended for embossing and engraving. You can process metal or stone with them. Before making a purchase, it is important for you to decide what you plan to do. For example, mini drills are often compared to impact engravers. The former are used not only for engraving. With their help you can carry out a whole range of tasks, namely:
- drill;
- clear out;
- Polish;
- cut.
Therefore, when purchasing, it is important to pay attention to the equipment. Some craftsmen emphasize that purchasing attachments separately may be too expensive. By choosing a model with a flexible shaft, you will be able to operate more maneuverably and accurately, especially in hard-to-reach areas.
Before you buy an electric engraver, you should consider how often you plan to use it. If every day, then you need to buy a reliable model from well-known manufacturers, among them the following should be highlighted:
- Dremel
- Foredom.
- Proxxon.
Experts emphasize that power reserves also matter. When it comes to a professional workshop, it is better to prefer an engraver whose power starts from 250 W. The main advantage of such devices is the impressive torque at low speeds.
An electric engraver can also be used for a hobby. In this case, a household-grade model is suitable. These are produced by companies:
- Sturm.
- Einhell.
- Skil.
- Hammer.
The average power in this case can be 200 W.
Selection tips based on processing material
Before going to the store, you should think about what you most often deal with: soft metals, wood or glass. In all these cases, a mini-drill with a low speed of up to 20,000 per minute will be sufficient. If the materials you are used to working with are steel, hard materials and precious stones, then an impact engraver is suitable.
A mini drill will do an excellent job with this task, but the rotation speed should be about 30,000 per minute. This tool must have a speed control option. This will allow you to configure the unit as accurately as possible, which is especially true when you have to do minor work.
Tips for choosing ergonomics
An electric engraver must be selected taking into account the ergonomics of the body. You should not rely only on the opinions of consumers and experts about a particular model. After visiting the store, you should understand how convenient the equipment will be for you to use. This is especially important because you will have to work with the device for a long time.
It should be comfortable and should not cause fatigue during prolonged use. If you still don’t know how to choose an electric engraver, you should evaluate the quality of the body material and assembly. Switches should be located in a convenient location. This also applies to governing bodies.
Change working attachments. These manipulations should not take much time. Try installing a flexible shaft. You should be comfortable doing this. An important factor is also the noise level. Many consumers also appreciate the smooth operation.
Before choosing an electric engraver, you should consider whether it operates with jerks, whether you hear clicks and squeaks during operation. Evaluate the design. Working with a beautiful device will be more pleasant than working with unattractive equipment.
If you purchase a model from a reputable brand, you will hear almost no noise during operation. Your hands will not feel the vibration. Working with such a tool will not be tiring, you will not experience discomfort.
Reviews about manufacturers
The modern market offers many engravers for sale, but professionals most often choose products from the following brands:
- DWT.
- Defort.
- Makita.
- Dremel
- Bosch.
Devices with modest technical characteristics, but quite high quality, are manufactured by the following companies:
As users emphasize, among domestic manufacturers it is better to pay attention to the following companies:
- "Energomash"
- "Bison".
- "Vortex".
Several factors may affect the price. For example, brand and functionality. The cost of professional models may differ significantly from the price of simple devices. Consider whether you want to pay extra for functionality if you simply don't need it.
You should also be careful when choosing an engraver whose cost is too low. Little-known companies today produce products that are not reliable or of good quality. In order to make the right choice, you need to consider several models, familiarizing yourself with consumer opinions about them.

Electric engraver: what is it and what is it for?
This tool is used in medicine and in jewelry workshops, at home and in the garage. It handles wood, stone and metal.
What types of electric engravers are there? Which one should you choose for your home and which ones do professionals use?
What is an electric engraver and how does it work?
An engraver is used for fine processing of wood, metals, glass and even stone. It is also called a hand mini drill or drill.
The design of an electric engraver is similar to an electric drill. Inside the housing there is an electric motor with a cooling impeller, which transmits torque to the spindle. At the end of the spindle there is a removable collet chuck, into which attachments of various types and purposes are clamped.
The body has an elongated cylindrical shape, convenient to hold with one hand like a fountain pen. In addition, a flexible shaft with an attachment can be clamped into the chuck, and the device itself can be mounted on a tripod.
Types of engravers and their features
Features: compactness and light weight.
There are impact engravers for engraving on metal or stone surfaces. This is a highly targeted type of device. Rotational type devices are more functional and widespread.
Like any other power tool, electric engravers can be divided into two categories: devices for home use and professional devices.
Devices intended for domestic needs are designed to work with wood, plastic and soft metals (copper, aluminum and others). Typically this is a low to medium power tool with a very simple design.
Professional models, compared to “household” ones, have higher technical performance. Such engravers have high functionality and can withstand heavy loads. With their help you can process almost any materials.
Functionality and application
The engraver is designed for work that is difficult or impossible to perform accurately with a standard tool. This is a universal device. With its help, you can drill small holes, grind and grind miniature parts, process surfaces in hard-to-reach places, make engravings and use them as a mini grinder.
An electric engraver is an indispensable tool in various fields:
- jewelry making: engraving and processing of jewelry;
- beauty industry: manicurists use special engravers;
- medicine: drill in dentistry, devices in operating rooms;
- hobbies: amateur radio, scale modeling and making various crafts;
- household: from minor repairs on the knee to work in the garage.
And this is not the entire list.
Components and consumables
For work, nozzles of various configurations and purposes are used. They can be solid or have replaceable working parts.
Drilling holes is done with ordinary drills. In your arsenal you must have a separate set for soft materials (wood, plastic) and a set for drilling metal.
For engraving, nozzles with cutting heads of various shapes are used. They have a one-piece design with no removable parts. Dental burs are often used as consumables.
Surface treatment is carried out using nozzles with tips made of abrasive materials of various grain sizes. For work, nozzles with cylindrical, conical, spherical or disk-shaped tips are used. The consumable element in such attachments can be a “sharpening” stone or an emery cloth.
Brushes (brushes) are used to clean surfaces. They differ in the shape and material of the bristles. Metal is usually cleaned with metal brushes, and for more pliable surfaces, brushes made of plastic and other similar materials are suitable.
Sanding is carried out using attachments with cloth, felt or other similar material. Such nozzles generally have a collapsible design.
An electric engraver can perform the function of a mini grinder. For this purpose, attachments with small cutting discs are provided.
Replaceable collet chucks allow you to use bits and drills with different shank thicknesses.
Features of the tool
In order for the job to be done perfectly, it is necessary to select the right attachments for each individual operation. In addition, the quality of consumables greatly affects the final result.
To increase accuracy, the workplace can be equipped with special devices for mounting the engraver. The use of a flexible shaft makes work convenient and allows you to do everything as efficiently and accurately as possible. Various stops and guides make machining much easier, increasing functionality and accuracy.
Electric engravers: which one to choose and what to pay attention to
When making a choice, you need to decide for what tasks the equipment is purchased. An engraver with a simple design and low power is suitable for a home workshop. Professional tasks require power tools that are an order of magnitude higher.
What to pay attention to:
- power and supply voltage;
- number of revolutions per minute;
- vibration level;
- duration of work;
- ergonomics;
- equipment.
Electric engravers are equipped with motors ranging from 50 to 300 W. For simple work, 150-200 W is enough. An engraver for professional use should have a power of 250 to 300 watts. The tool can be powered from a 220 V network or from a battery with a voltage of 12 to 24 V.
The spindle can make from 15 to 35 thousand revolutions per minute. For processing soft materials (wood, plastic, aluminum or copper), a device with a minimum number of revolutions is sufficient. Products made of steel, ceramics or stone require 30 thousand revolutions per minute. Stability of rotation under load is also important. Professional models can be equipped with electronic filling to stabilize the rotation speed.
High levels of vibration can negatively affect the quality of delicate work. A side effect is rapid wear of the nozzles and the occurrence of backlash.
The duration of continuous operation of “networked” engravers depends on the speed and degree of heating of the device during use. Professional models can be equipped with additional engine airflow. The operating time of an autonomous tool is primarily determined by the battery capacity.
Ergonomics. A good instrument must fit comfortably in your hand. It should be relatively light and have a balanced center of gravity.
High-quality tool - high-quality equipment. By the attachments and accessories included in the kit, you can judge the level of quality of the electrical appliance itself.
It is better to refuse outright “Chinese” immediately. A good choice would be to purchase a tool from a trusted manufacturer. From foreign brands you can safely purchase Dremel, Proxxon, Sturm, Ryobi. Domestic-made tools have good reviews: Energomash, Zubr, Caliber.

How to choose an engraver for metal work?
Craftsmen who process metal products in private workshops or garages are often faced with creating patterns on the surface of the material and carrying out precision work. For this purpose, a metal engraver is used, which has some design features.
Working as a metal engraver
Kinds
Engraving equipment is diverse. In stores you can find different devices that are designed to carry out certain technical operations. There are two large groups of metal engravers:
- Industrial equipment. Metal engraving machines used for mass production. Used in factories and large enterprises. These are wear-resistant, productive machines that can withstand increased loads.
- Devices for home use. Small models that are used when performing single jobs. The kit includes attachments for performing various operations.
The devices are also classified according to their operating principle:
- Impact type devices. These power tools work on the principle of a hammer drill. Used to create contour drawings on metal. When working with other materials, you need to take into account impact energy, which can damage the product.
- Devices with a rotating working part. This is a smaller version of an electric drill. Using such a tool you can drill holes, mill, grind, and sharpen.
Engravers can be battery or mains powered.
Design features
Before purchasing a device, you need to study its design features. The engraver consists of several key parts:
- Electric motor - drives the tool attachment. The more powerful the engine, the more materials the engraver can process.
- A spindle is a structural element in which the equipment is secured. Additionally, an extension flexible shaft can be installed on it, with which you can use the tool in hard-to-reach places.
- Housing - can be made of durable plastic with rubberized elements. It contains all the details.
Additionally, it is worth mentioning the tool control system and power supply. A multifunctional engraver must be equipped with a spindle speed controller. By changing the speed of the engraver, you can process wood, glass, and metal without damaging the working surfaces. The design of the tool depends on the type of power supply. If a battery is installed in it, the dimensions of the engraver increase.
Application area
A metal engraving machine for workshops and garages is considered a universal tool. There are different ways to use engravers:
- drilling holes in glass, plastic, wood, ceramics, metal;
- drawing patterns on metal surfaces;
- carrying out repair work;
- milling of parts;
- grinding;
- cutting small workpieces or thin sheet metal;
- polishing of parts.
Specifications
When choosing a power tool, you need to take into account the characteristics that affect the performance of the equipment:
- Electric motor power. When performing one-time work, choose a 200 W tool. If the engraver will be used constantly, choose a model with a power of 250 W or more. The optimal number of revolutions when working with metal workpieces is 30,000.
- Dimensions. Performance depends on the weight and size of the tool. If it is heavy or bulky, it becomes inconvenient to work and you have to take constant breaks. When choosing, hold the engraver in your hands to understand whether it is comfortable or not.
Advantages and disadvantages
Manual engraving machines have a number of strengths and weaknesses. Advantages:
- low noise level;
- ability to use in hard-to-reach places;
- a variety of equipment allows you to perform various technological operations;
- if you have a speed controller, you can work with glass, plastic, ceramics, and metal;
- If the model is equipped with a battery, you can use the equipment without connecting to the network.
Flaws:
- The main disadvantage of hand engravers is the rapid overheating of the electric motor. Therefore, during active work, the tool must be given time to cool down.
- Models with batteries retain their charge for a short period of time.
The cost of the engraver depends on the power of the electric motor and the configuration.
Which electric engraver should you choose?
When choosing an engraving tool, you must first select a location for the equipment. To use at home, you do not need to purchase expensive professional tools. For multi-batch production, industrial engraving machines are used. They are equipped with CNC systems, which facilitate the work of workers.
The power and rotation speed of the engraver's electric motor are selected depending on the frequency of its use, the material being processed, and operating conditions. The optimal power of models for garages and private workshops is 200–250 W. The spindle rotation speed for processing metal products is 30,000 rpm.
The shape, size, and weight of the engraver are selected depending on the ease of use of the tool. When purchasing, you need to try the equipment in action and hold it in your hands. The appearance, ergonomics, and color of the instrument depend on the preferences of the person.
The most famous company producing engravers is Dremel. Such tools are distinguished by their reliability, performance, and a large number of attachments.
Nozzles for electric engraver
When purchasing an engraver, you need to consider the quantity, quality, and purpose of the attachments. They are a structure of two elements:
- The shank is the part that is clamped into the tool chuck. Length - from 1 to 8 mm.
- Working part. With its help, the material is processed.
Nozzles differ in purpose:
- For cutting, the working part is equipped with a small-diameter cutting disc.
- For grinding, the attachments that perform this technological process are varied. These include grinding stones of different grain sizes, wheels with fixed strips of sandpaper, rubber cylinders, and diamond rings.
- For milling - cutters of different shapes.
- For drilling - drills of different diameters.
Burs are used to create grooves. For polishing surfaces, circles covered with felt or cotton can be used.
In addition to the main equipment, additional devices are used:
- Clamps for fixing the tool in one position. In this way, you can fix the engraver at a certain angle and process workpieces.
- Flexible shaft. Designed to lengthen the working part of the tool. With its help, you can increase the versatility of the engraver and work in hard-to-reach places.
It is better to choose equipment made of high-strength steel. Diamond-coated bits are expensive, but they last longer than other types of materials.
Metal engravers are used to perform various technological operations. To do this, they are equipped with certain equipment. It is important to carefully select power tools. The power is selected depending on the frequency of operation, the materials processed, and the operations performed.

What can an engraver tool do?
An engraver is a universal electric tool. Compact and powerful. With it in hand, anyone can perform grinding, drilling, milling, and engraving. An electric engraver is a small grinding machine with the more familiar name of a cutter.
In the convenient body of this device, which has an elongated shape, there is an electric motor and a rotating cartridge where the working nozzle is fixed. If you press the start button, the rotation of the equipment begins. Moreover, the equipment can rotate at speeds of up to several tens of thousands of revolutions per minute.
This can be used, for example, to process precious metals, steel, ceramics and other materials.
When using a universal engraver tool holding system, a large number of different types of interchangeable tools can be used. For example, these could be cutting or polishing discs, burs, drills, abrasive and diamond cutters, and milling cutters.
What is included in the engraver kit
Depending on the attachment, you can perform any kind of operation. For example, milling, sharpening, drilling, grinding. When we talk about grinding, we mean that an engraver is still different from a grinding machine. It's all about the roller cutter, which processes small products. And therefore the device is well suited for working in hard-to-reach places.
An electric engraver can be used at any stage of processing. Starting with roughing and ending with finishing. Using grinding and polishing wheels will allow you to achieve a smooth and shiny surface. Brushes are designed to get rid of rust and clean seams. Cutting wheels are needed to cut small parts of workpieces and smooth the edges.
A set of drills and cutters is useful when it is necessary to form holes and mill surfaces. Abrasives are used when grinding hard-to-reach areas. Feathers - for engraving work. Since the engraver is a compact instrument, it provides the opportunity to carry out inscriptions, minor restoration work, and make souvenirs.
What operations can be performed
When purchasing, it is best to choose a reliable tool, even if it does not have many attachments. The missing attachments can then be purchased separately.
In order to be able to work comfortably, the electric engraver is equipped with not only additional elements.
For example, there are rubber pads that are designed to better hold the device during operation. Due to the locking mechanism of the start button, you can get rid of the need to constantly hold it.
And with the help of the spindle lock button, you can change the equipment without straining.
Since an engraver is a device that has found application in grinding, cutting and drilling materials, it is used by, say, jewelry specialists and mechanics. And just people who decided to make an inscription on glass, metal, stone.
And depending on how one intends to use the engraver, one should purchase the device from the store with its subsequent use in mind.
How to choose an engraver
When choosing an electric engraver, you need to carefully inspect the motor, collet chuck and attachments. We warn you that there are also models that are equipped with a flexible shaft that serves as a rotation adapter to the nozzle.
Mostly all models have a device that regulates the speed of the rotating shaft. The kit includes a variety of attachments. They determine what function the engraver will take on. The choice must be made taking into account the type of work you plan to do.
The brand of the tool is of great importance. It is also important to consider who the manufacturer is.
The main criterion when choosing is the rotation speed. Engravers have a rotation speed of 15 to 35 thousand revolutions per minute. Low revolutions - for grinding and polishing. In order to cut and sharpen the sharpener, the speed must be maximum.
If there is an electronic regulator, then it indicates that this is a modern instrument, and therefore it costs accordingly. Cheap models usually have a simple device that reduces the voltage at the motor.
If the engraver has low tension, then he is not suitable for high-precision work. We also emphasize that the price and cost of the work performed is directly dependent on the power that the engine has.
Engravers, despite their compactness, may have different dimensions. The lighter the tool, the smaller its dimensions. However, such lightweight engravers do not have a cooling system. When it comes to choosing a portable engraver, this is something to consider. Otherwise, the engraver will quickly overheat. And it will be necessary to stop work every 10 or 15 minutes.
