It is important to know before buying: this sharpener has 2 installation pins for reliable fixation of the tool tire when sharpening the chain. One of the pins is movable. Most often on the tires of electro and chainsaws one hole was made. When using a sharpener with this type of tires, it is necessary to choose an even plane for the stop of the nozzle and work with it carefully, exposing the tire with a chain parallel to the faces of the nozzle. For maximum reliability, it is recommended to clamp the sharpener, create conditions for its immobility. Another method for complete fixation in a tire sharpener with one hole. This is the manufacture of an additional tool in the tire. This will not affect the technical characteristics of the saw, but it will solve the problem of simple sharpening the circuit.

Sharpening by improvised means

To properly sharpen the chain of the chainsaw with a file, you need to prepare tools to restore its functionality:

A round file is needed to process the edge of sawed teeth characterized by a rounded configuration. Usually choose a tool with a diameter of 4. 5.5 mm. A flat file is needed to sharpen the depth limiters, on which it depends on how the chain is cut into the structure of the wood.

The technology of sharpening the chain with a file

To sharpen the chain, you need to remove it from the saw, which, in turn, is installed on a flat surface. The tension should be maximum. The saw should be put on the brake. To do this, turn the lock lever. The chain is preliminarily examined for detecting defects that can be expressed in fragments, cracks, chips. Performing the sharpening of the chain of the chainsaw, take into account the main technological features:

  • The teeth are pulled from the inside out;
  • The degree of sharpening is determined by special marks made by the manufacturer;
  • Sharpening tooth is located in the middle.

Attention! Be sure to put protective gloves on your hands so as not to cut on sharp chain teeth.

To simplify the process, use special devices for sharpening chains of chainsaws in the form of holders, with which the depth of placement of the limiter and the angle of sharpening are determined. The correct machine is fixed on the tire with clamps and set the guides at an angle, through which the degree of sharpening is clarified. A tooth exposed to sharpening must also be fixed with an emphasis on the top of which the file is placed.

No matter what additional tools you use, first drag the edges, and then equalize the depth limiters. It is required to carefully approach the formation of the difference in the height between the plane of the limiter and the edge.

Step.by.step instructions for sharpening a saw with a file

  • sawing a saw;
  • installation of the holder taking into account the indications of the scale;
  • The angle of sharpening of the chain of the chainsaw is specified, by elevation above the tip of the holder by 1/5;
  • The minimum sharpening size is determined by the stupid tooth itself;
  • Start the procedure with a round file, smoothly performing movements from yourself. 2. 3 times for each tooth.

Attention! The file periodically turns over, which will avoid its uneven grown.

The teeth must be sharpened on both sides, turning the chain as the operation is completed. It is recommended to set the template for the limiter, placing the index part between the teeth. The ledge over the template is flowing with a flat file.

How to understand that the chain has become dull

The chain of the chainsaw enters into direct contact with the surface of the material and during prolonged work gradually loses its cutting properties. Dressing the edge of the teeth is a consequence of sawing a special solid wood or a saw of a too large tree trunk. In addition, grinding the saw chain can occur due to accidental contact with soil or stones. Reducing the sharpness of the saw negatively affects the productivity of the labor personnel and the accuracy of the cut of the tool, and also increases the fuel consumption. The consequence of the untimely sharpening of the chain is serious problems with the engine and the premature failure of the nodes and mechanisms. The main sign of the dull tooth is considered a poor immersion of the canvas into the surface. It can be noted other indicators that the teeth need sharpening:

atypical operation of equipment, extraneous noises, increased vibration;

After identifying the malfunction, a careful inspection of the equipment should be carried out. Changing the shape of the cutting link can lead to a deterioration in the quality of the cut or difficulty of the primary incision of timber. To guarantee high efficiency, any chainsaw must have a sharp tooth sharpened at the required angle and the corresponding height of the depth limiter. How to sharpen a chain of chainsaws with your own hands, as well as a description of each method, we will consider further.

Manual sharpening of the chain with a file

The editing of chains can be held manually. To do this, you will need a number of additional devices, such as holders, a hook for removing sawdust, round and flat file, vise or clamp. In this case, the chain should be strongly stretched in order to maintain the initial angle of inclination of the teeth. The tire must be reliably fixed in a vice. The stable position of the chainsaw will improve the quality of work. Further, with a detailed examination of the canvas, the shortest tooth is selected, which will serve as a standard for other segments. The cutter is set on the middle part of the tire, the brake of the chain is turned on. The sharpening of the edge is carried out by a round suction of the corresponding size, which is placed in the link in the chain of the chainsaw. The angle of the file is selected according to the template. After the instrument has taken the correct position, with smooth movements in the direction of yourself, a thin layer of metal should be removed. The operation is repeated sequentially for each tooth with an equal number of aisles, after which they move to the other side. In this case, the upper part of the file should not go beyond the extreme angle of the tooth by more than 1/5 of its own diameter. In the vertical plane, the file is located perpendicular to the axis, the horizontal angle is 10-30 degrees, depending on the characteristics of the equipment. At the final stage, the depth limiter is stuck with a flat file and a special sawing pattern. Thus, you can sharpen a chain of chainsaw at home without special skills. You can also note other advantages of this method:

universality (suitable for any chains);

The disadvantages include for a long time and the need for manual passage by a file of all teeth.

Strike with a clamp for sharpening the chain of the chain

When sharpening the electric or chainsaw circuit with a file, it is necessary to conveniently fix the tire on the surface. For this, a homemade clamp stand may come in handy. over, this device can be used both in the workshop and in marching conditions.

For the manufacture of a stand with a clamp for sharpening the chain of the chainsaw, you need a U-shaped clamp (you can make it independently from improvised materials), as well as 2 segments of a steel square. The latter will act as supporting legs of the device.

The process of manufacturing a home.made stand

First, from a square bar 15×15 mm, it is necessary to cut off two identical pieces of 20 cm long, which will be used as support supports.

On the one hand, each piece must be cut off at an angle of 45 degrees, on the other, it is sharpened under the cone.

The result should be two legs with a pointed end. Thanks to sharp ends, the tire stand itself can be installed on any wooden surfaces, stumps in the forest, and also in the ground.

Then you need an U-shaped clamp, with which the chain saw tire will be clamped. over, it is easy to make a clamp itself from metal scraps. To bend the square with the letter “U”, you need to use a bending machine.

Then it remains only to weld the legs to the frame of the clamp, and the home.made stand for sharpening the chain of the chainships is ready to work.

Additional recommendations on how to sharpen a chain of a chainsaw with your own hands

When working, you should strictly comply with safety requirements. It is necessary to work in gloves made of rough material so as not to injure your hands, since the working surface of the teeth is very acute.

If the sharpening technology prescribes the dismantling of the chain, it is not recommended to be attached to the threaded fasteners of excessive efforts with reverse installation. It is best to use the tire mounting screws to be tightened by the electric screw calibrated in the limb.

Experts recommend a way to increase the strength and wear resistance of chains, which is known as “Stabilization of the internal structure of the metal”. For this, a new tire for one and a half to two weeks at a temperature of 55-65ºС is warmed up in an oil bath. Operation confirms the effectiveness of such technology.

Nozzle for sharpening a saw chain using an engraver

one.JPG ” /

In today’s review, I want to share with you my impressions of a special nozzle for an engraver used to sharpen a saw chain (electric lily). I do not use a saw often and two available chains are enough for me for one season. After that, they go for sharpening and return to their place with the arrival of the next spring. I gave them to the sharpening or a friend (I had to ask) or in a special workshop (I had to pay). On the one hand once a year, to do this is not stressful, but on the other. to pay or asking for will never be pleasant. I never had a desire to sharpen the chains, and it was impractical to buy a machine, since I had to do it very rarely. In general, having stumbled upon this nozzle, looking at ebay, I didn’t even think about whether it is worth buying it or not.

The seller sent the parcel the day after payment. At the same time, it was equipped with a full.fledged track, so all the information about its tracking along the way from China to Belarus is available for viewing everyone who wants this link.

The nozzle is supplied without any original packaging, my copy was in the usual plastic bag on the fastener and looked as follows: the supply kit includes, in fact, the nozzle, ruler and 3 grinding stone itself is included. A few words about the quality of manufacture. So, everything is crooked and requires improvement. Although no, lying. The line is quite nothing and can be used in a state as it is originally. By the way, the ruler is combined with the key that is used for the clamp of the collar of the engraver.

Now about the grinding stones. They are nothing more than a metal base with diamond spraying on the working part. The whole trouble is that their tailings are too long. No, you can use them in such a state as they are, but then the working part will play for the “transporter” of the main nozzle and, accordingly, the angle of sharpening will have to be wondered by eye. In this photo, this is clearly visible: the benefit, to shorten the shank a little time and does not need time 🙂

The angle of sharpening of the circuit can be determined by the “transporter” available on the nozzle. In my case, he is closest to 35 degrees. But here it all depends on the specific chain. Now about the nozzle itself. There are no complaints about the plastic latch: the plastic is even, the thread is not bad, there is no extraneous smell or noble. But the processing of the metal component leaves much to be desired. If everything is in order with the “front” work part, then the part that adjacent to the plastic fixer is despondency. Just look at it

In principle, there is nothing more interesting both in appearance and in the device of this nozzle, which means that you can proceed to practical tests.

For the first tests that are reflected in this review, the chain was already removed from the saw, which caused some difficulties: for sharpening the circuit must be fixed with something. Of course, you can hold it with your hand, but it’s not very convenient. So it is best to work with the chain installed on the saw. So, before proceeding to sharpening, it is necessary to choose a grinding stone of a suitable diameter. In my case, it was the smallest of them (the diameters of complete stones are 4.5, 5.0 and 5.5 millimeters). For selection, holes are used on the left side of the ruler. Then we put on the nozzle on the engraver, clamp the grinding stone in the cartridge, using the ruler, centering the nozzle (the same self.tapping screw that I wrote above) and you can begin. This is what the chain tooth looks like to sharpen: if you look closely, then transverse risks are visible from the previous sharpening.

But the same tooth, but after the overflow with the help of a nozzle and engraver: the risks are already longitudinal, everything in the metal dust remaining as a result of processing. Here are traces of work on the nozzle itself: it is clear that the working part of the grinding stone is very short and protrudes beyond the limits of the degree line. After the first tooth, the shank of the stone was shortened, but I generally plan a trip to the market in search of the necessary stones with a longer working part. And I would like to have more than 3 working diameters.

From the moment the nozzle was received before writing the review, in addition to tested sharpening, a complete re.launch of the chain installed on the saw was carried out. The whole process took about 15-20 minutes, which is not so much. There are no difficulties with sharpening, the most important thing is to specify the nozzle. Then you won’t get too much and get into the right place with a stone easier. Interestingly, spraying on the stone after sharpening the chain has not changed in any way. Rather, it was a little clogged with metal dust and dirt, but it was not erased: in the end I want to say that this nozzle has the right to life. With its function. sharpening the chain, it copes more than decently. Of course, for industrial purposes, it is not practical to use it, and it is a pity for engravers. But if you sharpen the chains for yourself (and this is hardly more than 1-2 sharpening per year), then this nozzle, it seems to me, is a very successful option. The only thing that upset me was the quality of metal processing and the self.tapping screws used, but perhaps it is a single jamb, and for the most part, the metal processing is better. But since this does not affect the performance of the nozzle, then okay. The chain imprisoned by me with the help of this nozzle saws no worse than those that sharpened for me for money: it does not take it anywhere, the cut is straight and even.



The nozzle on the chain sharpening was invented relatively recently. The main difference between this device is that the chain can be sharpened with it almost anywhere, even in the forest. To do this, you do not need to remove the chain, pinch the saw shirt in a vice, giving it a strictly set position. Various guides will also not be needed in order to set a strictly defined angle of sharpening. Well, of course, do not take a set of files with you.

The nuance is that such a simple option is not suitable for every saw.

The nozzle will definitely be useless for old chains, for example, for the Soviet chainsaw “Friendship”. It is only suitable for her last modifications.

However, the chains of modern saws are quite realistic to sharpen such a device.

Modern automatic nozzles are produced universal size.

Often manufacturers produce a nozzle corresponding to the accepted characteristics of chain and saw tires of this particular company.

The problem may occur due to the unequal diameter of the front gear of Shinka, caused by various chains. It is this indicator that is the decisive.

If all the characteristics are selected correctly, the nozzle will easily return the working condition to the chains.

The main working part of this type of nozzle is an abrasive stone specially curved in the form of a crescent form.

Currently, a special nozzle for a drill is used to sharpen the teeth of chains, which goes along with a set of abrasive diamond heads. Such a diamond head is intended primarily for grinding, but using it to restore the severity of the teeth gives a very good result. The hardness of mineral spraying is enough for repeated sharpening of steel chains.

The kit also includes a platform with a peculiar transporter necessary to select the optimal angle of sharpening.

If the first type of nozzle is more suitable with frequent intensive use of a saw, then the second is better to use with rare, irregular use of a saw, only several times per season, for example, in a summer cottage or personal plot.

How to use

The use of a special nozzle on a chainsaw, like many modern gadgets, is not distinguished by the requirement of any complex skills. You can master it anyone who knows how to use a saw.

The nozzle is fixed at the end of the tire, then it takes no more than 5 seconds to drive the saw at high engine speeds. Here, in general, and all. Having removed the nozzle, you can continue to work.

At the same time, it is quite convenient to use it right in the forest, since the device is devoid of any removable small details that are easy to lose. Another important point is the presence of built.in fasteners. Do not need keys, screwdrivers, pliers.

Despite the widest unification of modern technology, yet different manufacturers often reserve the right to independently determine the parameters of their products.

This is somewhat complicated by the use of nozzles, so it is better to select the device of the same company as it made a saw.

Иногда приходится просверливать в шине дополнительное монтажное отверстие для шпильки насадки. This usually does not affect the characteristics of the tire. Often the abrasive element of the nozzle is not compressed enough to the chain, which can also be associated with the inconsistency of the set parameters of the chain parameters. in this case, the practices are recommended to slightly squeeze the nozzle, resting it on the stump or trunk of the tree.

You can see a nozzle for sharpening a chain of a chain in action in the next video.

“During the use of a chainsaw, I realized that no machine could sharpen better than hands! I have been with saws for 20 years, but I sharpened the machine only when I need to quickly and without norms in acuity. He began to work with the Urals and the taiga, even worked on a roll of forest, and after now I am engaged in log cabins and in general wooden buildings. All of these machines of bullshit, especially when the turnover is large and the circle is spinning in one direction. “.

Other options

The saw chain can be sharpened with other improvised tools. Acting correctly and sequentially, you can achieve good results even without a machine. The main difficulty here is that to fix the working area, as well as withdraw the desired angle when working with a power tool on weight is almost impossible.

corner grinder (angular grinder)

Despite the fact that this method is often mentioned as an alternative to the machine.sharpening of the chain, it is difficult to recommend it for use. Even experienced masters cannot cope with tasks perfectly. What can we say about newcomers. The difficulty with fixing a certain angle of sharpening requires the use of auxiliary devices.

The corner grinder can be fixed in a vice, stationary, and then handed the teeth to the surface of the rotating disk, but this approach can lead to serious injuries with non.compliance with safety precautions.

Difficulties when using corner grinder include a high risk of rupture of the chain. With any careless movement, the cutting element angular grinder can damage the hinge connection. In this case, the dispensed section of the chain will fly off arbitrarily, increasing the likelihood of an injury for a master that performs the work. The sharpening process consists in the supply of the chain to the saw disk. The duration of contact is best done as on the machine. This will reduce the risks of metal overheating. It is better to leave the chain on the tire, as with manual sharpening. The rest of the procedure will be the following.

  • A disk is installed on the corner grinder. It is better to choose a cut.out circle for metal work with thickness indicators up to 2 mm.
  • A buffer is installed between the chain and the tire. You can take a piece of chips or other improvised material.
  • Sharpening is performed. It is important to measure the desired angle in advance.
  • The tacing of the chain. It will be needed after sharpening in any way.

The sharpening of the teeth of the chainsaw using angular grinder has obvious advantages. This is the speed of work, the lack of additional costs, if the tool is already available. The disadvantage is also quite obvious. too high risks, it is necessary to carefully observe safety precautions when working with a corner grinder.

Drill or drill

Using this type of tools involves the work by analogy with manual sharpening. Mechanization allows you to slightly accelerate the process. But here you need to monitor the exact positioning of the work area. For use in combination with a drill and a drill, special sharpeners are available, including the following equipment elements:

The rag of the replaced file is fixed in the cartridge of the power tool. It is selected in diameter, taking into account the corresponding step of the saw chain. After that, the equipment is installed on the drill or drill, its adjusting screw is weakened. It is aligned and fixed along the ruler.

The tool is brought to the tooth of the chain, the rotation of the tip is activated. Nadfil, as with machine processing, grinds all sides of the tooth at once. The average duration of the entire tape is no more than 15 minutes.

over, the accuracy of the effect is very high.


Before proceeding to sharpening, it is worth making sure that the saw is really necessary. There are 5 simple assessment criteria that can confirm this.

  • Reducing the size of sawdust flying off during operation.
  • Improving the efforts attached during the use of the tool. It becomes noticeably more difficult to saw.
  • Bouncing, uneven chain stroke.
  • The appearance of obvious signs of displacement of the geometry. It just “takes” him aside.
  • The smell of burning, the appearance of smoke from under the chain.

Continuation of the work with a pointed tool, whether it is an electric or gasoline unit, threatens not just by reinstalling a shift element. In some cases, overloads disable much more expensive nodes, which will not be so easy to change. Another important point is to check the quality of sharpening at the end of the work. There are also obvious criteria here, which show that the chain is completely ready for work.

It is important to achieve the severity of not only the upper, but also the lateral cutting edges. The corners of all teeth should be the same, as well as their length. These parameters are determined by the manufacturer of the tool. The angle of sharpening is selected based on the method of sawing wood. During a transverse saw, it is made in the range from 25 to 35 degrees. With longitudinal enough and 10.

It is worth paying attention to the depth limiter. Its indicators vary in the range from 0.5 to 0.8 mm, but it is better to rely on the recommendations of the manufacturer, sometimes the recommended parameters differ from the standard. The depth limiter affects the level of tool performance, with a decrease in indicators, it decreases. It is also not worth exceeding the recommended values, because during operation, vibration will be strongly felt.

Among the useful tips given by specialists in sharpening saws, the following recommendations can be distinguished.

  • Service of the chain after work. It is worth blowing it with compressed air, and then plunge into the engine oil for a while (clean, not working out). This will significantly extend the term of operation of the chain.
  • Selection of time for running.in. It is carried out first at low speeds, within 60 seconds. This time is enough for the lubricant to be evenly distributed, and the asterisk and links warmed up, got sick. After that, the circuit is cooled, it is re.adjusted and tension.
  • Following the operating rules. When sawing after sharpening, it is important to avoid the inclined position of the chain. If necessary, it is necessary to periodically adjust the tension of the links. Under load they can sag.
  • Periodic processing in a machine way. Even if you restore the severity of the teeth in the “field” conditions by a file or drill, if such an opportunity arises, it is worth performing a full.fledged metal processing. The machine provides higher geometric accuracy, makes it possible to straighten the defects that arose when working with the tool.
  • Control of grilling teeth. After 3-4 operations to restore their severity, it is worth checking the suitability of the chain for further operation. Changing the depth of cut and other defects will indicate that the element requires replacement, not recovery.

Important recommendations for the sharpening of the chain saw include the use of protective equipment.

Be sure to protect your eyes with shields or glasses, carry out work in gloves. Injury, especially with instrumental sharpening. is not uncommon.
