Types of saw blades for electric jigsaw, their features and the right choice. BOSCH classification of saw blades for jigsaws and reciprocating saws Marking of jigsaw blades table

The electric jigsaw is universal power tool, with which you can cut various materials, making straight or curved cuts. With this tool, you can possess such various materials as wood, glass, metal. For each type of work, it is necessary to select a certain type of files.

In order to choose the right file for a particular job, you need to find out what parameters you need to pay attention to, what characteristics of the file differ from each other, how to read the marking correctly.

Looking at the photo of saw blades for a jigsaw, it can be seen that they differ greatly from each other in external dimensions (length, width and thickness), the shape of the teeth, the type of attachment, the material from which the saw blades are made and, accordingly, their purpose. Below is an overview of jigsaw files, with a description of the characteristics and features of the choice.

Types of fastening saw blades

There are several types of saw blade tails. Any power tool is designed to work with only one type of files, so when choosing files, you should pay close attention to this issue.

The most common type of shank is the shank in the form English letter T. This type of mount was developed by the market leader in electric jigsaws - Bosch. Following the leader, such mounts are used by other equally well-known manufacturers. Therefore, such files are the most common.

Having such a tool, you may not be aware of the existence of other types of saw mounts. Nevertheless, the existence of files with other types of fasteners should be noted.

Such files have one or two holes for attaching equipment, as well as old Bosch fasteners with a double T-shank, which has not one, but two stops.

Blade length

It can be different: from 4 to 25 cm. The longer it is, the thicker the workpiece can be cut. For thin workpieces, it is better to use short blades, this will improve the quality of the cut, since in a short file there are no large deformation movements compared to long files up to 25 cm long.

The maximum thickness of the cut material also depends on the technical characteristics of the power tool.

File width

The width of the file is selected depending on the planned work. If you need to make long straight cuts, then you should choose a wide file. If you need to make a figured cut, then a narrow file is better to handle this task.

File thickness

The quality of the cut also depends on this parameter, but a blade that is too thick or too thick may not be suitable for a specific quick-clamping mechanism.

A thin canvas deviates less from the vertical during operation, and the cut is more even. Therefore, without special need, it is better to use files of standard thickness.

Blade cutting edge geometries

The geometry of the files is determined by the setting of the teeth. It can be simply milled with a wavy or classic setting, in addition, the teeth can be ground with a classic tooth setting and with conical tooth grinding without their setting.

Ground teeth differ from milled ones in that they are additionally ground at an angle to increase their sharpness, the spreading of the teeth increases productivity and the width of the saw. This increases its unevenness.

Classification of blades for electric jigsaw

As well as saws for manual jigsaw Power tools come with a variety of accessories designed to work with various materials. Wood canvases are the most common, as this tool is most used when working with this material. The design of jigsaw saw blades for wood is determined by the parameters of the work.

For high productivity, saw blades with a large tooth width of up to 6 mm and a large setting of up to 1 mm are used. These saws are needed for rough work. If a neat cut is required, then they work with files with smaller teeth and with a slight divorce.

When cutting, pay attention to which side does not form chips and scuffs when working on the material. On this side, the material must be placed face down. This is determined by which side the teeth are located on the canvas: towards the jigsaw or away from it.

A neat cut on both sides can be made if you use a two-row blade with multidirectional teeth. To cut curly lines, use narrow files of small length with small teeth with back side having a bevel.

Metal files are made from durable steels, they have very small teeth - up to 1 mm. Individual files are produced for different metals. There are three main types of jigsaw blades for metal: for aluminum, other non-ferrous metals and steel. You can get by with one tool if you rarely have to cut metal.

To work with polymers and plastics, canvases with large teeth are used. Blades with small teeth are also suitable, but be aware that in this case, sawdust can melt and clog the teeth of the blade. Thin plastic can be cut at low speed with a wood blade.

Can be cut with a jigsaw ceramic materials. For this, diamond-coated or tungsten carbide-coated saw blades are used. Such a tool is not replaceable, if necessary, to perform a figured cut.

File marking

Appointment and specifications files are indicated in the markings on the side surface of the blade. Marking is quite simple. The first letter indicates the type of attachment. For example, T-shaped. The following is a number from 1 to 7, characterizing the length of the canvas.

The next two digits indicate the purpose of the blade, and the next letter at the end of the marking describes the size of the teeth (A-small, B-Medium, C and D-large). The last letter gives Additional information about the blade: F-bimetallic, O-narrow, P-thick, R-reverse direction of teeth, X-variable size of teeth.

To start with, it is advisable to purchase a set of jigsaw files, consisting of a set of files for different materials and then expand it if necessary. Expendable materials determine the quality of work and ease of use of the tool.

It is impossible to say unequivocally how to choose the best jigsaw file. Some files give great performance, others provide very good quality incision. The correct choice of saw blade determines the efficiency of the work.

Photo of jigsaw files

Manual and electric jigsaws have long "taken root" among home craftsmen. This is very useful appliances, which will allow you to accurately and accurately cut almost any material of various thicknesses and configurations. But before proceeding with the work, it is necessary that the jigsaw file is correctly selected. However, immediately accept correct solution pretty hard. This is due not only to a large selection, but also to a huge number of types of canvas.

Some general information

If you have a jigsaw and no files, then this is a useless tool. If you have a whole set of files, then you can cut almost any material. No need to think that the jigsaw is designed to work only with metal or plastic products. While you might say that it makes sense to have both manual and automatic tools, you'll see why in a bit. With proper skill, you can make straight and figured cuts on chipboard, ceramics, metal, and so on. But it is worthwhile to understand that for each type of material there is a jigsaw file. For example, the BOSCH product range includes a wide variety of blades that can work with plywood, plastic, etc. Of course, each material has a different thickness, density, hardness, and other parameters, which imposes certain requirements on the quality of the blade steel.

Jigsaw blades

It is quite logical that without a file you will not be able to perform the work you need. Today, all blades for hand tools are divided into two large groups:

• for woodworking;
• for metal work.

Each of these groups is divided into subgroups. For example, a canvas for wood can be for quick cutting. This is one of the most common and popular files. Its peculiarity is that such a canvas can be processed a large number of material at high speed. For example, with such a file it is not a problem to cut a workpiece with a diameter of 20 cm. However, this tool leaves behind a significant number of defects, so it is advisable to use it only for auxiliary work or the construction of buildings.

But files for a manual jigsaw of a clean cut allow you to get a high-quality surface. This is achieved due to the large number of small teeth, as a result of which the cut is smooth and practically free of defects. However, in this case, the maximum diameter of the workpiece should not exceed 7.5 cm. There are also files for laminate. They have a unique arrangement of teeth that do not leave any marks behind.

Blade for working with metal

It is one thing to process a material such as wood, quite another - metal. Please note that the wood blade is not suitable for cutting metal sheets. But learning to distinguish files from each other is extremely simple. The jigsaw file for metal has a blue shank, which is the main hallmark. The teeth are very fine, allowing you to work with sheets with a thickness of 6 mm.

Today, combined canvases are increasingly being sold. According to the manufacturers, they are well suited for working with wood and metal. But we can say with confidence that this is not the best solution, since the work performed is somewhat difficult and stretched over time. In any case, a jigsaw blade for metal must be made of high-quality material.

Electric, desktop and manual jigsaws

It should be understood that, despite the same purpose, the files for this tool have fundamental differences. For example, the blade for a manual jigsaw is quite thin and long, and is also attached on both sides. In a jigsaw, it is shorter and thicker, and also has a completely different installation method. If the tool is manual, then you should always have several spare files. This is due to their fragility. They break really often and at the most inopportune moment.

There are also saws for The tool itself is stationary and great for cutting wood. The canvas in this case is more similar to the one used in hand tool. However, it is less brittle, so it breaks less often. Such files are designed for workpieces with a maximum diameter of 4 cm for wood and 0.2 cm for metal products.

Jigsaw saw blade marking

Special designations on the canvas can say a lot. Firstly, this way you can find out what material the product is made of. By the way, this is very important, especially when performing responsible work. For example, if HCS is written on the body, this means that the blade is made of and is intended for cutting soft materials, in particular wood, chipboard, plastic, etc. But, for example, the inscription HSS indicates that the file is made of high-speed hardened steel. It is a hard, but at the same time quite brittle material that can be used to work with both aluminum and steel of small thickness.

But the marking of BIM jigsaw files means that the blade is bimetallic. Basically, it is a combination of HCS and HSS. Such a file has improved properties, but also a high cost. The HM stamp means that such a blade can be used for especially hard materials, for example, cutting ceramic tiles etc. In principle, it is not so difficult to understand the markings, if you remember this, then choosing the appropriate canvas will be extremely simple.

Learn more about making the right choice

When buying, you should always pay attention to the blade shank. Naturally, it has only one mount, unlike a manual saw. Although today the world famous company Bosch releases with two stops. In any case, it is advisable to first read the instructions, where it will be written what is suitable for your tool. For example, the Makita company produces jigsaws with a mount that is fundamentally different from other models. At both ends there are specially sawn circles of various diameters. Naturally, you can no longer put a file with a different type of fastening on a jigsaw.

You need to understand that the canvas can have a different length. For wood cutting, this is usually 51-126 mm, for metal - up to 106 mm. The choice should be based on the thickness of the workpiece to be machined. The thicker it is, the longer the canvas should be. For example, to perform curly cut on wood, thin jigsaw files are used. They are quite fragile, but give more opportunities to the operator.

Canvas for laminate flooring

Today, many say that for processing parquet board or laminate, an exceptionally clean cut is required. Someone may advise using almost a diamond-coated canvas. However, the price of such a tool is very high, for a set of 5 files you will have to pay several thousand rubles. In principle, sometimes the jigsaw itself can cost so much.

So, it is not at all necessary to purchase an overly expensive tool. A blade is usually sufficient for a clean cut. Of course, there will be a chip of about 1-2 mm. However, in most cases, the laminate is closed with skirting boards that are much larger than the chip. For this simple reason, do not overpay once again. When buying jigsaw blades for laminate, pay attention to the quality of the product. Many modern canvases burn very strongly when working with wood, chipboard and laminate. Therefore, make a purchase with a small margin.

Something about the shape of the teeth

The blade tooth configuration determines the capabilities of the tool. A large number of small teeth improves the quality of the cut, but significantly reduces the speed. If there are few teeth and they are large, then such a cut will be extremely sloppy, but very fast. Conventionally, according to the shape of the teeth, the saw blade can be divided into the following groups:

• Diluted (milled) - used for cutting soft materials such as wood and plastic, as well as non-ferrous metals. The wiring contributes to the fact that excessive heat does not accumulate, and sawdust is removed from the cut and the blade.
• Wavy (milled) - used for clean cutting of aluminum, soft materials (wood, plastic) and non-ferrous metals. The wiring in this case is performed in groups, that is, several teeth in a row in one direction.
• Conical ground (ground) - good decision for clean cuts in wood and plastic. The non-working edge is polished. These are typical jigsaw blades for laminate.
• Ground, set teeth - one of the best solutions for rough cutting of wood, chipboard, blockboard, etc.

Web width and thickness

When choosing, it is extremely important to pay attention to the width of the file. Not only the quality, but also the speed of the work performed depends on this parameter. If the canvas is wide, then it will be not only stable, but also more durable, and will practically not deviate from the intended plane. Of course, this is also high-speed cutting, do not forget about it. At the same time, narrow files provide good maneuverability compared to wide ones. The location of the teeth on the axis of the jigsaw drive allows you to better follow the intended plane with minimal deviations.

Thickness is also not the last parameter that makes sense to pay attention to. Blades that are too thin cannot ensure the proper perpendicularity of the cut. In addition, the thicker the file, the higher its stability.

Something else

You probably know that the blade teeth must be harder than the material being processed. So, to perform work on cutting glass, ceramics, metal and stone, you will need special files. The main requirement is increased strength. It is best to use bimetallic sheets for such purposes, which are 1/3 hardened steel and 2/3 high-carbon steel. The service life of such files is quite large, so they will pay off with interest. In addition, the risk of a sudden breakdown here is much lower than in the classic versions. But since choosing a jigsaw file is not difficult, and you already know how to do it, you will not have any problems choosing the appropriate bimetallic blade.

Conclusion

If we talk about manufacturers who have proven themselves well, then these are Bosch, Makita and Praktika. Files of these companies are famous all over the world for their high quality and excellent performance properties. If you are not afraid to spend an extra 200 rubles, then buy canvases of these brands, and you will not regret anything. Do not forget that all files have their purpose, use for other purposes is unlikely to lead to the expected results. The jigsaw is a high-speed tool, so securely fasten the blade and try to work with goggles and gloves. In principle, we examined the main types of jigsaw files. Now you know that there are canvases for wood, metal, as well as combined ones for other materials. Paying attention to the labeling of the product and the way it is attached, you will definitely make right choice.

What kind of saw blades exist and how to choose the best option for a particular case, every craftsman who has this tool in his household should know.

There are many factors influencing the choice of cutting blade: the material to be sawn, its thickness and density, the required cut quality, etc. In order not to make a mistake when buying, you should take into account the technical characteristics of the files, as well as the advantages and disadvantages of a particular model.

Cutting blade material

The first thing you need to pay attention to when choosing a file is the material from which it is made. Each cutting blade well-known manufacturers has its own label. Knowing how to decipher it, you can easily determine whether the file is suitable for you for the upcoming work.

The marking indicating the material of manufacture of the canvas is as follows:

1. HCS. Such files are related to wood tools. They are made from high carbon steel with plasticity and elasticity. They can cut wood, chipboard, plywood and plastic. When choosing such a canvas, you should pay attention not to its hardness, but to its flexibility.
2. HSS. Hardened steel products that can work on high speeds. Used for processing durable materials, including metals of various densities. Despite all its rigidity, hardened steel is a rather brittle substance that must be handled with great care.
3. BIM. Bimetal blades, which are made from a mixture of high-carbon and hardened steel, due to which they have all the advantages of the first two types. Depending on the shape and size of the teeth, they can be used for both woodworking and metalworking.
4. HIM. Manufactured from high-strength alloys, due to which they are characterized by high strength and rigidity. Mainly used for cutting ceramic tiles.

The color of the file can also indicate the material of manufacture and the purpose of the file:

• white (BIM) - for cutting wood and metal;
• gray (HCS or BIM) - for processing wood and materials based on it;
• blue (BIM or HSS) - for cutting metal;
• black (HIM) - for special tasks (sawing ceramic tiles, durable steel, etc.).

Jigsaw saw blade marking

Files intended for working with wood are marked with the letters HCS.

On the tail of any cutting blade for a jigsaw there is a marking consisting of letters and numbers. The first is the letter "T" or "U", which indicates the type of fastening of the blade to the tool: T-shaped or U-shaped. It is followed by numbers indicating the length of the file:

• 1 - short canvas (up to 7.5 cm);
• 2 - standard cutting element (7.5-9.0 cm);
• 3 - elongated file (9-15 cm);
• 7 - long file (more than 15 cm).

The longer the product, the thicker the workpiece can be cut with it.

The numbers are again followed by letters that indicate the size of the teeth:

• A - the smallest teeth (perfect for cutting laminate);
• B - larger teeth (used for processing wood, fiberboard, chipboard and plywood);
• C and D are the largest teeth used for rough cutting.

Some manufacturers use two instead of one letter at the end (for example, T101BR). The second letter means:

• O - for curly cutting;
• R - with a reverse tooth (improves the quality of the cut);
• F - bimetallic products (considered the most durable and reliable);
• X - universal blade (they can cut both wood and metal);
• P - thick files (used for corner cutting).

For example, the T118AF marking means that the selected model has a T-shaped mount and fine teeth, its length is up to 7.5 cm, and the material of manufacture is bimetal.

Choosing a saw blade for its intended purpose

When choosing a cutting blade for a jigsaw, you need to know what material it will work with. This tool is able to cut not only wood and materials based on it (chipboard, fiberboard, plywood, etc.), but also plastic, slate, brick, metal and even tiles. At the same time, for each material being processed, there is its own type of saw with which the jigsaw will work with the best efficiency. There are also universal cutting blades that are equally well suited, for example, for wood and metal.

Wood saws. Depending on the purpose, such products are divided into two groups:

• for fast cutting
• for a clean cut.

If you are faced with the task of sawing a large amount of wood, while spending a minimum of time, then the best option would be a cutting blade with large teeth.

The larger the teeth, the faster the cut. However, as the speed of work increases, the cleanliness of the cut decreases, so here you need to choose between speed and quality.

If the speed of work is in the first place, then the best option would be a canvas marked T101D. With it, you can quickly cut wood up to 7.5 cm thick, for thicker material, you can purchase the T244D or T344D model.

For a clean cut good option is a file T101B. It is often used for professional purposes when assembling furniture and other jobs that require a quality cut. This product can also cut thick workpieces, but you will spend twice as much time on this than when using, for example, the T244D model.

Fabric on laminate. When laying laminate flooring, it is important that the cut is free of burrs. This can be achieved with the T101BR file, which is equipped with a reverse tooth. However, if you don’t have this model at hand, and you need to cut the laminate with something, you can get by with the usual T101B blade. Only in this case, before starting work, it is recommended to paste over the place of the intended cut with ordinary adhesive tape, which will protect the processed material from chips, burrs and other defects.

Metal saws. They have small teeth and a blue tail. If you work with metal 3 mm thick, buy a T118A file. It is also suitable for cutting plastic. For thicker material, a T123X blade is recommended, and for aluminum, a T227D blade.

Tile saws. They are marked T150RIFF or T130RIFF. Instead of teeth, their cutting part is carbide coating. You need to know that it is recommended to use a jigsaw for cutting tiles only in extreme cases, as the work will be slow and high level dustiness. In the absence of a specialized tool for cutting tiles, it is better to use a conventional glass cutter.

Blade shape

For various tasks, a certain shape of the teeth is suitable, which differs not only in the type of sharpening, but also in the wiring method:

1. Milled set teeth. This blade is perfect for cutting wood. Divorce is carried out by analogy with the usual hand saw. This allows you to slightly expand the cut, thereby preventing overheating and jamming of the tool in the thickness of the tree.
2. Milled teeth with wave setting. In this case, not a single, but a group wiring is performed (for example, 4-6 teeth each). These blades are used for cutting metal.
3. Ground teeth without setting. The best option for fine cutting. This canvas allows High Quality cut in wood, laminate and plastic.
4. Grinded set teeth. Such a product is used for fast cutting, when there are no special requirements for the quality of the cut.

1. General classification
2. Wood saws
3. Nail files for working with metal
4. Homemade files
5. Option 1: regular serrated blade
6. Option 2: spiral file

A hand jigsaw is a versatile tool for woodworking and metalworking. They can cut the product into pieces of the desired size, even into the thinnest fragments - the cut will remain even and neat. Materials with different densities and textures require the right blades, so each home master a variety of files for a manual jigsaw should be in stock.

General classification

Blades for a manual jigsaw are divided into 2 main groups according to their purpose:

• for woodworking;
• sheet for metal carving.

The blades differ in the material of manufacture, its technical properties, number, location and frequency of teeth. Accordingly, each type of file cuts metal or wood differently, leaving behind a cut of different quality.

Wood saws

Blades for working with wood are also divided into groups:

Files for working with metal

You can cut with a hand jigsaw metal sheets using a special file. Her canvas is equipped with small teeth, located strictly one after another. The blade is made from durable steel.. You can recognize the file by the blue tail - this is how all metal files are marked.

The frequency of the teeth of a saw blade for metal is 9-10 per 1 centimeter.

Universal Blade: Fact or Fiction

Jigsaw blades are sold in sets of 10 or more pieces, since they often break during work, you have to insert new ones. The packaging may not contain information about the purpose of the products, because they are used mainly for working with wood.

There is no universal blade, you can cut a piece of wood and metal with any nozzle. Another question is how the problem is solved, and what will be the place of the cut. It is impossible to get a fast and smooth cut at the same time. You have to choose: either quickly or beautifully.

Working with plastics and polymers

Cut if necessary plastic product, for example, to shorten a window sill, cut a polycarbonate sheet and in other cases, it is better to give preference to a file with small cloves. It cuts the material evenly, the cut remains even, and the structure of the material near the cut does not suffer.

Homemade files

Blades for a manual jigsaw for wood may have different shape teeth, the frequency of their location. Various manufacturers offer standard saw blade shapes, so craftsmen are constantly looking for new solutions, both in order to save money on ready-made jigsaw nozzles, and to improve the quality of their work.

We will consider 2 master classes on making different files for a manual jigsaw.

Option 1. Regular serrated blade

The blade blade often breaks during operation, which significantly complicates the process of manufacturing products from different materials. The cost of a quality canvas can be very high (from 50 rubles apiece). Cheaper products are made from fragile metal. To solve the problem and reduce the cost of jigsaw attachments, craftsmen figured out how to make a serrated blade on their own.

For work you will need:

• strong wire of large diameter;
• forging plant;
• hammer;
• grinder with nozzles.

Procedure:

1. To begin with, we take an ordinary jigsaw blade and cut the wire along its length, you can make a small margin for ease of use.
2. On the anvil, we beat off the wire with the blunt side of the hammer to the state of a flat strip. Do not flatten the metal much, we try to maintain the usual thickness of the finished file by eye.
3. You can put the finished strip in a jigsaw. We clamp it into the tensioners like a regular file.
4. We take a drill with diamond disc and saw teeth with the desired frequency and size. The hand should move confidently, observing the chosen step.

Homemade is ready to go. This process is described in the video.

Option 2. Spiral file

This product is in ready-made craftsmen are often criticized: the magazine spiral blade is often ineffective, and the installed blade does not work as expected. The cost of a quality product is from 50-60 rubles apiece. Masters figured out how to save on the purchase of a spiral file and make it really effective.

What is required for work:

• metal tin can (not aluminum);
• pliers;
• hammer;
• anvil installation.

The master on the video shows the process of making a spiral file.

Stages of work:

1. We cut off the bottoms from the can and roll out the rolled metal.
2. We cut off narrow strips of the same width (1.5–2.0 mm).
3. We clamp the ends of the strip into pliers and twist evenly.
4. After twisting, we carefully stretch the twist to straighten it.

At this stage, the work can be completed. The product can be installed in the tool. If the thickness of the blade turned out to be more than necessary, we correct the situation with a hammer and anvil - slightly flatten the twist. Ready!

For those who have in their household jigsaw, from time to time must acquire files for it. There are a lot of varieties and manufacturers. The most common types of saw blades are, of course, for wood, besides them there are blades for metal, tiles. In order not to get particularly confused in the choice, we will consider the most popular files in everyday life, from the Bosch company. In terms of price / quality - a good choice. The letter "T" in the marking indicates the type of shank - T-shaped. The most common type of saws.

Wood saws. There are several types, it all depends on the nature of the work being done.

For example, if you need to quickly cut a bunch of boards, then a saw with large tooth. The larger the tooth, the faster the cut will be, but less accurate, the cut is not very smooth, but if you are making a fence, or building a barn, then accuracy, in principle, is not needed.
For these purposes, you can take a file marked T101D. Suitable for boards up to 75mm thick.
If the board or bar is up to 100mm, a 244D saw will be required.
For boards up to 200mm - long file 344D.
It can be seen that the larger the number in the marking, the thicker the board is intended for sawing.
It should be noted that a thick board will require.

For a clean cut, you will need a file, for example, T101B.

File for a clean cut Т101B

Her tooth is noticeably smaller, respectively, the cut is smoother. This is suitable for assembling furniture, where you need an accurate and even cut, without chips.
Often it is used for sawing fiberboard, plywood, chipboard.
She can also saw thick boards of course (up to 75 mm), but in time it will take longer than files with a large tooth.

File for laminate.
It has a reverse tooth, directed in the opposite direction compared to the rest of the files. This is done so that there are no chips on the front side of the laminate, do not spoil appearance. Fine tooth for a clean cut. It is marked T101BR.

The letter "R" - stands for reverse (reverse). And so it is no different from a simple tree T101B.

Files for a figured cut.

Their tooth is always small, they are used for sawing out a radius, a circle, they are used in the manufacture of furniture. In shape, they are noticeably narrower than all the others, this is done so that the file does not pinch when turning the jigsaw.
From personal experience I can say that I sawed a circle in a fiberboard plate for a sink, the cut turned out to be very accurate and even.
The marking of such files with the letter "O" in the name is T119BO.

They always have a small tooth, so that it is easier to recognize them, they have a shank of blue color. If you cut metal up to 3mm, a T118A file is suitable, it can also cut plastic, for metal up to 6mm - T123X, for aluminum - T227D, its tooth is larger.

Combined file.

You can cut both wood and metal with this. Her tooth is small on one half of the canvas, large on the other. Marking T345XF.

File for ceramic tiles. It is marked T150RIFF, T130RIFF. On the edge it has a carbide coating.

Coated with carbide

Most often, the files are clamped into a jigsaw with a 3mm hex wrench, sometimes there is a quick-clamping mechanism.

As for prices: the most popular files cost about 25-40 rubles, long ones for a thick board are about 80 rubles. Stands out from general series file for ceramics, its price is 150-170 rubles. Prices are current for 2012.
