Jigsaw files: the main types of fastening options and marking files (150 photos). Wood saw for a jigsaw, for metal, tile, chipboard - an overview of the blades for solving various problems All types of saws for a jigsaw

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 range includes a wide variety of blades that can work with plywood, plastic, etc. Of course, each material has different thickness, density, hardness and other parameters, this imposes certain requirements on the quality of steel sheet.

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 process a large amount of material with 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.

And here are the saws for manual jigsaw clean cut allow you to get a 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 canvas 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, however, high cost. The HM stamp means that such a canvas can be used for special 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 produces 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 a figured cut on wood, thin jigsaw files are used. They are quite fragile, but give more possibilities 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 classic options. But since choosing a jigsaw file is not difficult, and you already know how to do it, you will not have 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 the right choice.

Today we will analyze the types of files for an electric jigsaw, because when choosing, the buyer has a lot of questions. There are a lot of types of files, because with an electric jigsaw you can cut not only wood, the list is much longer. Therefore, in this article we will figure out which files are better to cut a simple tree, and which chipboard or fiberboard, which saw blades different kinds metal.

And of course, we will pay attention to the marking, therefore, after reading this article, you will begin to figure out which file is suitable for which work. After all, it’s not in vain that there are on files different letters and numbers. What do they mean? We will analyze all this using the example of popular Bosch models, since they are of good quality and their price is very low.

Marking

If you have ever been to a tool store, you have seen that there are letters and numbers on the shank of any file. Let's figure out what they mean.

The letter T means the type of fastening, that is, T-shaped (Fig. 1). It also happens U, is much less common (Fig. 2).

The numbers on the shank mean:

The first number is the length:

1 - standard short, length up to 75 mm.
2 — average length, up to 90 mm
3 - extended, up to 150 mm
7 - the longest (over 150 mm)

The following letters indicate the size of the teeth:
A,B,C,D

Tooth A is the smallest, so all metal files have A, for example T118A means - a file with a T-shank, a short, very small tooth. Further, respectively - B - a slightly larger tooth (most often these are files with a small tooth for plywood, chipboard, fiberboard and wood for a clean cut). Files with the letters C and D - with the largest teeth, for wood for rough sawing.

There are also files with two letters at the end at once, for example, the T119BO model, so let's look at what the last letter means:

F - from bimetal (the coolest, high quality)
R - with reverse tooth
X - universal for wood, metal and plastic.
O - for a curved cut (cut a circle, for example, usually thin, so that the file can be turned straight during sawing).
P - thick options for sawing strictly at the exact chosen angle (thick, do not bend, so they cut perfectly). Bright representative- T144DP, costs much more than standard ones.

woodwork

The main purpose of an electric jigsaw is sawing wood. For this purpose, there are a huge number of files and they are all different. Let's go in order.

If you need to cut ordinary boards and you don’t care about the quality of the cut, its cleanliness, you work at speed (for example, sawing ordinary boards for firewood or for a fence), then buy jigsaw files with a large tooth. Thanks to this, the sawing speed will be high, and if you work with a jigsaw in pendulum mode, then everything will be just fine.

In addition, also pay attention to the length of the file, since sawing a board or bar with a thickness of 70 mm (for example) will not work as usual, you will need an elongated one.

Well, the third nuance when choosing is the thickness, standard files are not thick, but there are thickened ones (they cut much better, because they do not bend). Since most jigsaws use a standard mount (t-shaped), the name of the files for such a mount begins with the letter T.

See the photo for a standard set of nail files:

Well, now we will analyze each file separately, what it can saw, for what work it is more suitable.

For metal.

T118A - a standard metal file, has a very fine tooth (like metal blades). You can cut metal up to 3 mm, though there is a terrible rattle, so use protective headphones. Highly recommend. Also, due to the fact that the tooth is very small, it is also recommended to cut plastic, many finishers do this.

These are 5 files that we constantly sell together with electric jigsaws. By and large, they are enough for all household chores.

In addition to the standard saw blade for metal, there are special options for any other metal. For example, an aluminum file has a larger tooth, so that the teeth do not clog. After all, aluminum is a soft metal, so the standard for metal is very quickly clogged with chips.
T224D - for aluminum, special. It says Alu on it.

Sawing on tiles, stone and porcelain stoneware.

Not everyone has tile cutters and grinders, so they came up with special files for jigsaws on tiles. The blade has a tungsten carbide coating instead of teeth, which actually cuts any stone surface.

T150Riff - special for tiles, the cost is about 250 rubles. Perfectly cuts tiles.

Processing of abrasive materials.
Processing of metal products of various hardness.
Processing of wooden products.
Cutting tool (they have a combined blade and are used for wood and metal products).
Processing of stainless steel.
Processing of various plastic items.
For processing products made of fibrous materials.

Fibrous materials are divided into:

laminate;
ceramic products;
cement.

The performance of the jigsaw depends on the size and pitch of the teeth on the blade, which is used to process the material.

When buying a cutting blade, you must consider the length or thickness of the material that will need to be cut. The length of the file should be 5 mm more than the thickness of the material, plus the stroke of the jigsaw.

Form of the cutting part

The teeth of the jigsaw blades are its cutting part. It can be subdivided into:
saw blade characteristics table

Table of characteristics of saw blades for wood.

The cutting part, in which the teeth are milled, divorced. The set of teeth, which are bent through one to the right and left, prevents heating of the cutting tool, helps to remove sawdust that is formed as a result of the cut. The width of the file layout is done professionally if it leaves a cut equal to one and a half the thickness of the blade. Such varieties are used for fast cutting of wooden, plastic, metal products of various hardness.
Cutting part with milled teeth in the form of waves. The cutting tool is adjusted not through the tooth, but several pieces in opposite directions from each other. Such a canvas is used when it is necessary to obtain a clean and even cut. This is true when cutting plastics, non-ferrous metals and other non-hard materials.
Cutting part with ground teeth. It has a conical shape. Such cutting tool, with conical processing is used for "fine" cutting of plastics and various breeds tree.
The cutting part with set teeth is ground. Such a cutting tool is used for fast, inaccurate sawing of small diameter wood (up to 50 mm). It is used to work with fiberboard and chipboard.

For the convenience of consumers, manufacturers have developed a special marking and put it on the tail of the cutting device. This marking uses groups of letters and numbers.

Explanation of designations
Designations on the saw blade

The first number indicates the length of the cutting blade. It can take a value from 1 to 7. The number 7 "says" that the length of the file is more than 15 cm.

The letter behind the first digit indicates the size of the teeth (A, B, C, D). The symbol "A" stands for very small teeth, and any metal cutting tool has this designation.

F - the most expensive cutting tool (bimetal blade);
R - cutting tool with teeth in reverse side;
X - universal blade for metal, plastic and wooden products;
P - the thickest blade, this cutting tool is used when cutting different materials at the chosen angle, they do not bend due to their thickness, the cut is perfectly even;
O - blade for a curved cut.

Naturally, for the processing of various materials, manufacturers make canvases from different brands become.

for files, cutting wood, use high-carbon steel (HSE - High Carbon Steel). In fact, carbon is one of the cheapest and most effective alloying additions, when, with its increase in iron, hardness increases sharply, but ductility is lost. Carbon in carbon steels reaches 2%. The hardness of such steel is quite able to ensure the processing of wood.

Large teeth provide greater depth of cut, but can break the edges of the tree. To prevent tree breaks, it is necessary to use files with fine teeth, with a minimum feed. Also, for sawing wood, the technology of sawing along the fibers or diagonally relative to them is effective.

A file for a straight cut holds the direction well, however, it will not be possible to cut a small radius using it - such a file has a wide back, which is why it “holds the line” so well. For a curved cut, a special thin file for a curly cut is suitable. The back of such a saw blade is much narrower when compared to a saw blade designed for straight cuts, often the back is even narrower than the shank. It is almost impossible to make a direct cut with its help - at a long distance it instantly leads to the side.

Other Choice Tips

Using an electric jigsaw, you can process solid wood, plywood, chipboard, chipboard, cut out various shapes, cut parts, adjust their dimensions to the desired parameters. The tool is universal, has different saw blades. Exist standard set nozzles.

Main selection criteria

You need to pay attention to:

Nozzle performance.
Cutting accuracy.
Cutting line quality.
The structure of the processed material.
The shape of the teeth, the pitch with which they are located on the base.
The width of the canvas, its thickness.
The material from which the jigsaw blade is made.

Each type of base has a different strength of resistance to the canvas. So, a laminate saw cannot be used to work with solid wood. There are blades for stainless steel, ceramics, hardened cement, fibrous materials. Nozzles must be used strictly for their intended purpose..

Tooth shape

Allocate:

Milled divorced. The teeth are bent in different directions. This prevents excessive heating of the blade during operation, allows you to remove sawdust that has fallen between the walls of the cut. Suitable for plywood, hardwood, softwood, plastic, non-ferrous metals.
Wavy milled. The layout of the cutting base is carried out in groups. Several teeth at once deviate first to the left, then to the right. This allows you to get a clean, chip-free cut, to make a straight line. Suitable for materials made of aluminium, plastics, non-ferrous metals.
Teeth with conical grinding. Are used for production of a pure cut of a tree, plastic.
Divorced polished. They are used for sawing soft wood, chipboard, chipboard, fiberboard.

Jigsaw files
Working tooth length	Part size (pitch)	Divorce	Usage	What it looks like (click to enlarge)
75 mm	8 s / d (3 mm)	Side	Soft hard rocks up to 60 mm thick. Especially for longitudinal sawing. Rough cut.
75 mm	6 s / d (4 mm)	Undercut and lateral	Like the previous one, but drank clean
67 mm	6 s / d (4 mm)	Undercut	Solid and soft rocks, artificial wood materials up to 60 mm thick. Very clean cut.
50 mm	12 s / d (2 mm)	wavy	Artificial wood materials up to 30 mm thick. Very thin cut.
50 mm	12 s / d (2 mm)	wavy	For cutting sharp curves in wood and artificial wood materials up to 20 mm thick.
75 mm	10 c/d (2.5 mm)	Undercut	Reverse tooth for downward sawing. For plastic coated boards.
60 mm	6 c/d (4.5 mm)	--	Tooth tips coated with tungsten carbide, especially good results when working with chipboard with a high content of adhesive mass.
70 mm	--	--	Semicircular flat and triangular files. For wood and artificial wood materials.

When buying, you need to pay attention to the height of the teeth. Smaller ones provide accurate sawing, but the blade will work slowly. Large ones will allow you to work quickly, but the cut line is rough.

different pitch

When choosing a part, you need to take into account the pitch - the distance between the tops of the teeth. It has letter designation t. There is a table made up like general recommendation to the choice of saw blade. Its basis is a formula that indicates the number of teeth per inch of blade. If the marking indicates TPI 7, then there are 7 teeth per inch.

If it is necessary to make a longitudinal straight cut of a wooden base, it is better to choose a nozzle with the following parameters: t=3.5–6.5 mm, TPI 7.
For general carpentry work, medium-pointed bits, t=3 mm, TPI 9, are suitable.
For figure sawing - with small sharp protrusions, t=2 mm, TPI 9–13.

In order for the tool to vibrate less in the hands during operation, it is better to choose blades with at least 5–8 sharp protrusions in one step.

What should be the width of the nozzle

The greater the width, the more stable the nozzle in operation, the fewer deviations from the cut cavity. For curly lines, it is worth choosing narrower canvases. If the teeth are on the drive axis, the tool will be easier to control.

Nozzle thickness

For sawing a strictly perpendicular line on a thick wooden base thicker nozzles must be used. How thinner material, the thinner the canvas should be.

Attachment form

Shanks can be with one stop and T-shaped fastening, two stops and U-shaped fastening.

Marking features

Nozzle types:

For cutting any kind of wood. With a gray tail (marking is applied to it).
For wood with metal. With a white tail.
For metal. With a blue ponytail.
For plastic tiles, cardboard. With a black ponytail.

From the marking you can find out what metal the part is made of. The abbreviation HCS means that the blade is made of high carbon steel. HSS - high speed steel. BIM - from bimetal. HM - Carbide.

For cutting plywood, softwood, chipboard, Chipboard thickness no more than 30 mm, plastic is better to choose HCS canvases. The teeth of such files have a pointed shape, conical grinding. High flexibility prevents breakage. HSS files are designed for cutting metals. They have a curvature in the lower part, it is necessary to prevent metal scuffing. These bits are thinner than wood cutting blades, but they are harder.

Bimetal nozzles are durable. They are made by laser welding. Based on high carbon steel. The back part is formed from it, the teeth are made of high speed steel. The nozzle is suitable for cutting curves and straight lines. HM blades are designed for sawing lightweight concrete, fiberglass, tiles.

For laminate, veneered boards, a canvas with reverse system teeth. The cutting occurs in the opposite direction, towards itself. This move allows you to process details different lengths, get a clean line, no chipping.

Manufacturer's brands

Manufacturer only trademark BOSCH releases a large assortment nozzles. Market share - about 90%. HITACHI, MAKITA and other electric jigsaws also include many different saw blades, but parts are made by third parties.

It is important to take into account the power of the tool, the ease of mounting the blade in the holder. Professional jigsaws are sold in cases. The kits include accessories.

The electric jigsaw is a versatile 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 attachment was developed by the market leader 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 files for a manual jigsaw for power tools, various equipment is available 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 files 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.
