How to sharpen a chainsaw chain with a file
No matter how high-quality the chainsaw is, sooner or later you will have to learn how to sharpen the chain yourself. Professionals use a machine for this purpose. Their services are not cheap. But in fact, you can get by with a simple file. Experts will teach even beginners how to sharpen a chainsaw chain with a file.
How to choose the right file
In order not to sharpen a chainsaw chain for days, it is important to choose the right tool. Craftsmen recommend processing the teeth with a round file. Flat is used to adjust the height of the tooth, thereby limiting the depth of cut.
The diameter of the round file can be 4-5.5 mm. Focus on the size of the saw teeth. The sharpening process will be facilitated by holders designed specifically for working with files. You can also try videos that indicate the sharpening angle.
As for a flat tool, its width should be no more than 1 cm. Grind out the limiting tooth using a bar. It is installed on the chain and the depth to which the tooth needs to be ground is determined. The goal is to achieve optimal functionality of the chainsaw.
Useful sharpening tools
Beginners are interested in what a holder is. It works with a round-shaped tool and assumes the presence of clamps. There are markings on the holder, each of which fixes a specific sharpening angle. When working with a holder, it is important to place markings parallel to the equipment bus. This approach helps to accurately maintain the desired angle of inclination.
Also in the theory of chainsaw sharpening you can come across the term filing gauges. Devices are used to control not only the sharpening angle, but also the distance to the depth stop, but only when working with a flat tool.
A clamp is another product that holds the tire while sharpening. Sharpening is carried out at the cutting site. The manipulation consists of successive steps:
- The clamp is fixed in wood or board.
- Then the tire is fixed in the board and pressed tightly so as to avoid possible displacement.
- The device is suitable for all types of tires. Their size doesn't matter either.

How to sharpen a chainsaw chain correctly?
≡ March 13, 2015 Category: Construction and repair
The excellent productivity of a chainsaw is mainly influenced by its proper operation, and the most important thing is caring for the chainsaw chain - it must always be sharp.
Only when the chain is perfectly sharpened can you work with a chainsaw very comfortably, plus play it safe.
Many highly professional lumberjacks say that a perfectly sharpened chainsaw chain is much more important than the power of its engine.
How to calculate when a chainsaw chain needs sharpening?
Symptoms of dullness are quite easily recognized:
- Reduced speed of the chainsaw;
- The saw begins to move from side to side;
- The type of shavings will change (a lot of dust appears in the shavings, and sawdust becomes like needles).
How often should you sharpen your chain?
You need to know that there is no specific time frame for sharpening a chainsaw. Experts recommend only sharpening the saw a little before using it.
The dullness of the chain will depend on how often you use it. According to this, as you work, carefully look at the distinctive symptoms and this will be enough.
Sharpening a chainsaw chain is not that difficult and absolutely anyone who has at least some skill in sharpening any cutting tool can handle it. But still, without specialized devices, you won’t be able to handle it.
The chainsaw tooth has a complex geometric shape; it consists of two edges: the side and the top, beveled at a specific angle. All this makes the operation somewhat difficult.
In this article we will give a couple of surefire ways to sharpen a chainsaw chain with your own hands.
Sharpening a chain with a file

This option will require you to minimize the cost of purchasing equipment, since a similar device, like a file, is in every home tool box.
First, you should look at the diameter of the file, it will depend on the size of the chain being sharpened:
- For a chain with dimensions of 1.3 mm, a file with a diameter of 4 mm is suitable;
- For a chain with dimensions 1.6 mm, a file with a diameter of 5.2 mm is suitable;
- A flat file is used to remove “stops” from cutting teeth.
When sharpening a chain with a hand file, you need to make a specific finishing angle on the cutting tooth. To help you, each link chain tooth has a specialized factory serration - which shows a high sharpening angle.
It is this angle that you must use as a guide when sharpening your chainsaw with a round file.
In addition to the cutting tooth, each chain link has a limiter that determines the greatest depth of insertion of the cutting teeth into the wood. Sharpening of the stops is not done very often, but only when necessary, when sharpening reduces the height of the cutting tooth and makes it difficult to actually operate the chainsaw.
A clamp is considered a very important auxiliary device when sharpening a chainsaw chain with a file. Its main function is to fix and secure the saw bar. Basically, the clamp is attached to the edge of a table or workbench. A perfectly attached saw is a guarantee of success when sharpening.
There is another auxiliary device - a pattern. It is mounted on a chainsaw saw bar and is equipped with rollers for movement. You select the best sharpening angle for you and fix it using a pattern. Next, you will only need to move the file in the groove of this device. Thanks to the pattern, you can reduce the risk of incorrect sharpening and its complexity to a minimum.
Advantages of the method: The most inexpensive and common sharpening option.
Disadvantages of this method: It takes a lot of time and effort. Basically, a file after such sharpening will not last very long.
Sharpening a chain by hand
Photo of sharpening a chain using a manual machine
Not every chain can be sharpened perfectly with a file. If, for example, the cutting edge of a chain has lost its shape, then sharpening it with a file will require a lot of effort and time from you.
In such severe cases, the most correct solution would be to use a chainsaw chain sharpening machine.
Machines are divided into manual and electric, equipped with a sharpening stone or sharpening wheels. This option will be particularly specific, although it is not something new.
The preparation process goes like this:
- First, you should slightly loosen the chain clamp adjustment screw;
- Next, you need to place the chainsaw chain so that its links are directed towards the sharpening stone;
- And finally, set the chain sharpening angle you need.
Sharpening can be done in 2 ways:
- Methodical sharpening. The teeth are trimmed gradually, one after another (changing polarity);
- Sharpening every second cutter. Right-handed, then left-handed, or opposite, as you wish. With this kind of method, there is no need to change the polarity.
When using the method of sharpening a chain using a manual machine, you must follow specific rules:
- First. It is necessary to calculate the ideal degree of sharpening of the chain based on the bluntest tooth - it is your main guideline in this matter;
- Second. There is no need to grind the chain deeply, this significantly reduces the strength of the link and the operating time of the chainsaw;
- Third. Immediately after sharpening, we strongly advise you to blow the chain with compressed air, then put it in clean oil for several hours.
Advantages of the method: The most specific way to sharpen a chainsaw chain.
Disadvantages of this method: time-consuming and labor-intensive.
Sharpening a chain on an automatic machine
Automatic chainsaw chain sharpening machine
Very often used in reality is automated chain sharpening on special machines. People call them “machines” or “automatic machines”. Such devices are often used in woodworking establishments, workshops and sawmills, as well as at home.
The device is a small “box”, in the middle of which there is a built-in sharpening stone. The saw is placed in the box, and then secured and covered.
Next, the chainsaw is turned on at full power, and the chain that starts to move is sharpened on the built-in sharpening stone.
Advantages of the method: The process takes minutes!
Everything is quite easy and simple, it does not require any special skills or physical effort on your part. Disadvantages of this method: In addition, you need to purchase specialized chains, which are produced by the same manufacturer as the device itself.
Sharpening a chain with a grinder

Many people consider this option to be “ruthless” and that it can ruin the chainsaw. This is a mistake, although many agree that this option, regardless of its own fame, is considered very difficult to sharpen, and an inexperienced person can completely damage his own instrument.
So, if you are planning to sharpen a chainsaw chain for the first time, it is better to use the initial 2 options listed above.
The specifics of this option are:
- Basically, when sharpening a chainsaw chain with a grinder, the chain is not removed from the tool;
- It is better to use a 2.5 mm disc for metal, plus the disc must already be used (with rounded edges);
- You choose the sharpening angle visually and it is better to install a wood wedge between the underside of the chain and the bar;
- If you have excellent use of an angle grinder and can carefully sharpen a chainsaw chain in this way, then the chain will serve you for a very long time, approximately four to seven sharpenings.
Advantages of the method: A very inexpensive sharpening option.
In fact, it takes neither time nor effort on your part. Disadvantages of this method: Requires dexterity and special skills.
Whichever of these methods of sharpening a chainsaw chain with your own hands suits your taste, you need to remember about safety precautions.
Naturally, wear protective gloves and use a face mask, this can help you avoid injuries when sharpening and the process itself will be very enjoyable for you.

How to Properly Sharpen a Chainsaw Chain with a File
Do-it-yourself chainsaw sharpening
The chain tooth planes wood like a plane, and the thickness of the chips is adjusted by the height of the stop.
The intense work of the saw leads to rapid dulling of the chain. How to properly sharpen a chainsaw chain with your own hands. Several sharpenings may be required during the first day. The problem is also made worse by the fact that the tooth quickly becomes dull when it meets the ground. How to sharpen a chainsaw chain correctly. It is enough to hook the tire into the soil once or twice, and you can stop working. the chips become small and the saw stops going deeper into the tree.
The earlier dull teeth are sharpened, the less material must be removed during sharpening, as a result. The service life of the saw chain is longer. Finding the moment when sharpening is required is quite easy. The main feature is the feed force.
A correctly sharpened chain is pulled into the cut even with a slight pressure. If, on the contrary, the chainsaw is forced to cut by increased feed force, then the teeth have become dull.
A dull chain can also be recognized if, instead of large thick chips, only small chips fly out of the cut.
In this situation, the chainsaw must be sharpened urgently. Do not cut with a dull or defective saw chain. the result is high tension in the body, high repetitive load, and poor cutting results. How to sharpen a chainsaw chain with a file yourself. How to properly sharpen a file before sharpening a chainsaw chain. In addition, this means a decrease in productivity, high fuel consumption and increased wear on all components of the chainsaw.
Chain teeth parameters
To achieve good cutting parameters, the tooth blades are given certain angles. The back of the tooth falling at an angle backwards forms the rear corner of the upper blade . This angle is needed to cut the upper blade into the wood.
The back-tapering blade of the tooth forms the rear angle of the end blade. Tips on how to sharpen a chainsaw chain with a grinder. This angle is needed for side cutting of chips.
The edge of the end blade forms a rake angle with the sliding surface of the cutting link. Rake angles for different types of chains vary from 60 to 85°.
The rear angle of the upper blade describes the backward tilt of the upper blade .
This angle is measured relative to the sliding plane of the cutting link and, depending on the type of saw chain, ranges from 50° to 60°. The top blade is the main blade, and the rear corner is the top blade. this is the most important angle. The back angle of the upper blade is difficult to measure; its correct value is formed by observing other prescribed values.
The sharpening angle or leading angle is obtained by measuring from the top cutting edge at right angles to the guide bar.
The sharpening angle can be changed depending on the application. The basic rule: the larger the sharpening angle, the higher the cutting performance when cutting unfrozen soft wood. Reducing the sharpening angle when cutting frozen and/or hard wood makes the saw run smoother and reduces vibration. However, sharpening angles of more than 35° and less than 25° should be avoided (the exception is rip saw chains, in which this angle is 10°).
The rake angle, sharpening angle and top blade angle change during sharpening. These angles have a decisive influence on the cutting ability of the chain. Be sure to observe the prescribed values.
A depth limiter is located on each cutting link in front of the tooth blade. The difference in height between the top edge of the depth stop and the leading edge of the back of the tooth is defined as the depth stop distance.
The depth of cut of the upper blade into the wood (chip thickness) and thus the productivity depends on the distance of the depth stop. The depth stop distance is set depending on the chain pitch and type of design. How to properly sharpen a saw + attachment for. Normally it should be 0.5-0.8 mm, more often 0.6 mm.
Higher values will make the chainsaw more prone to kickback, excessive grip and chain vibration. Low values lead to poor performance. You can sharpen a chainsaw chain by hand or how to sharpen a chainsaw chain with a file.
Since the distance of the depth stop decreases with each sharpening of the saw due to the reduction of the upper edge of the tooth, the depth stop also needs to be filed periodically. after 5-10 sharpenings of the chain.

Chain sharpeners
The round file holder has lines that allow it to be positioned correctly relative to the chain. The holder is installed on the tooth being sharpened in accordance with the orientation lines. In this case, the plate itself rests on the upper edge of the tooth and the depth stop, and the file is located under the cutting edge.
Using a holder ensures that the file rests on the tooth at the correct height. There are different holders available for different saw chain pitches. The correct choice of holder in combination with the correct file diameter ensures that the file extends 1/5 of its diameter above the back of the tooth. Use only special files for sharpening saw chains.
Before sharpening the chainsaw chain, it is advisable to secure the bar. When sharpening, it is necessary, while maintaining the position of the holder and pressing the file against the edge being sharpened, to make several (2-3) turning movements away from you. There is no need to try to press the file too hard; movements should be smooth and measured.
Turn the file regularly to avoid one-sided wear. How to sharpen a chainsaw chain correctly? All other teeth are sharpened in the same way. Discs for sharpening chainsaw chains, how to sharpen a chainsaw chain, share the article: saw chain - cutting tool. Designed for.
It is more convenient to first sharpen the teeth of one direction, then change the position and do the same with the teeth of the other direction.
When sharpening all teeth, make the same number of file strokes using the same pressure. How to sharpen a chainsaw chain with your own hands? This will ensure that the teeth have the same length. All cutting teeth must be the same length. Different tooth lengths cause uneven movement of the chain and the formation of cracks in it. If the tooth lengths are not the same, all cutting teeth should be filed to the length of the shortest tooth.
After several sharpenings of the cutting teeth, the depth stop is ground off. To do this, a template is placed on it so that the stop fits into the slot, and the tip protruding from the slot is ground off with a flat file.
Such sets, with different configurations, are sold in many stores that sell tools, for example, various sets and individual files are sold here (it’s better to buy through an online store, because in a regular store of this network the price may be higher).
The principle of using another kit for sharpening chainsaw chains is no different from the first, although its design is different.
A round file is also used to sharpen the cutting tooth, and a depth stop is used to sharpen the depth stop. flat. A special template provides sharpening parameters for both cutting teeth and stops.
In the first case, it is placed on the chain so that it fits into its slots. The file, placed on the template and brought under the cutting edge, rests on the guide rollers. How to sharpen a chainsaw chain at home: video.
The direction of movement of the file should be parallel to the side edges of the template.
When grinding the stopper, the template is applied so that the stopper fits into the slot, next to which it says SOFT (for soft wood) or HARD (for hard wood). As in the case of the first device, grinding is done with smooth, even movements of the flat file away from you.
Chainsaw chain sharpening machines
Stihl produces two modifications of hand-held machines. stationary FG 2 and mobile FG 1, installed directly on the bus. How to properly put a chain on a chainsaw photo. How. Ways to sharpen a chainsaw chain at home. There are analogues from lesser-known companies, comparable in price to the simpler devices described above, for example this one.
The working part of these devices is structurally reminiscent of a bow saw, into which a long round file is inserted instead of a saw blade. FG 1 and FG 2 not only sharpen chains, but also straighten them, adjusting the length of the upper edge of all teeth to the same size. according to the smallest tooth, which is taken as the control one.
A rather complex configuration mechanism allows you to set all the necessary parameters. Sharpening is done in 2-3 movements, after which they proceed to the next tooth, maintaining for it all the settings that were made for the control tooth. This ensures the same sharpening parameters for all teeth.
When grinding the stopper, the round file changes to a flat one.
An electric sharpening machine for chainsaw chains is simple and easy to use. It has an adjustment system that allows you to set the chain at the desired angle and bring the disc exactly to the edge to be sharpened. There are machines that automatically clamp the vice when lowering the disk onto the chain.

How to sharpen a saw chain correctly? — Metals, equipment, instructions
Electric and chainsaws are included in the arsenal of many private home owners, along with such devices as a drill, hammer drill, etc. This tool has one negative side - the chain gets dull from time to time. You can sharpen it yourself if you know how to do it correctly.
How to determine if a chain is dull
Anyone who has ever used a sharp chainsaw will quickly understand when the chain needs sharpening. There are several ways to determine this:
- instead of shavings, when cutting wood, practically dust falls out;
- the time of operations increases;
- you feel the strain on your hands;
- fuel consumption increases;
- the saw gets stuck and breaks out of your hands;
- The cuts turn out crooked.
Sharpening should be carried out as soon as possible, and not only because it becomes difficult to work with the tool. When using an unsharpened chain, its service life is shortened and the mechanism of the chainsaw itself wears out faster and fails ahead of schedule.
What to sharpen
Sharpening a chainsaw chain is not an easy process. There are three options that are used today:
- using a file;
- Bulgarians;
- special sharpening machine.
Similar methods are used when sharpening knives, scissors and other cutting tools, so nothing extraordinary has been invented here. However, there are also special tools for sharpening the PowerSharp system. They allow you to quickly sharpen saws at home, which have a special mark indicating the design features.
File
Using a set of files is the most common method that can be done at home. But it is not as simple as it might seem at first glance. To carry out sharpening, you will need two types of files: round and flat. Each of them has its own purpose.
Using a round tool, you need to sharpen the working edge of the saw tooth, because its configuration is rounded. For household chainsaws, a file with a diameter of 4-5 mm is used, because the saw teeth are small. Professional saws are sharpened with files with a diameter of 5.2-5.5 mm.
Use a flat file to sharpen the cutting depth limiter. If this edge is not adjusted, the chain will not cut into the wood to the required depth, which will reduce the cutting speed. And this will directly affect both excessive fuel consumption and overheating of the saw engine.
How to sharpen with files correctly
First of all, the power tool must be prepared. It is installed on a flat surface, it can be a table or a workbench. The chain is tensioned to the maximum, set to brake mode, for which the locking lever is turned. The saw teeth are inspected for defects: chips, cracks, complete fractures, etc.
As for the process of sharpening chainsaw chains with your own hands, there are several recommendations:
- The teeth must be sharpened with a file from the inside out;
- there is a mark on the chain that the manufacturer applies specifically to indicate the degree of sharpening;
- The tooth to be sharpened should be located in the middle of the chain for ease of work;
- sharpened, removed the chain from the lock, moved the next tooth to the middle, and put it on the brake.
You need to work with the saw carefully, wearing protective gloves, because the teeth of the chain are quite sharp. The number of movements along the plane of the edge varies depending on the damage to the teeth.
Accessories
Construction stores sell special holders that make it easy to sharpen the chain of an electric or chainsaw, because they clearly indicate the sharpening angle and the depth of the stop. Having installed the device on the chain, you just need to adhere to the configuration of the holder without going beyond the stops. In principle, this will not work, so the teeth sharpened on the holder have the required angle and depth parameters.
