Using an electric jigsaw, you can process solid wood, plywood, chipboard, chipboard, cut out various shapes, trim parts, adjust their sizes to the desired parameters. The tool is universal and has different saw blades. There is a standard set of attachments.

Main selection criteria

You need to pay attention to:

• Nozzle performance.
• Cutting accuracy.
• Cut 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 file is made.

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

Tooth shape

Highlight:

• Milled set. The teeth are bent to different sides. This prevents excessive heat blades during operation, allows you to remove sawdust trapped between the walls of the cut. Suitable for plywood, hard and soft wood, plastic, non-ferrous metals.
• Wave-shaped milled. The cutting base is laid out in groups. Several teeth deviate at once, first to the left, then to the right. This allows you to get a clean, chip-free cut and make a straight line. Suitable for materials made of aluminum, plastic, non-ferrous metals.
• Conical ground teeth. Used for production clean cut wood, plastic.
• Set apart, polished. Used for cutting soft wood, chipboard, chipboard, fiberboard.

Jigsaw files
Working tooth length	Part size (step)	Divorce	Usage	What it looks like (click to enlarge)
75 mm	8 w/d (3 mm)	Side	Soft hard rocks up to 60 mm thick. Especially for rip sawing. Rough cut.
75 mm	6 w/d (4 mm)	Undercut and side	Same as the previous one, but drank clean
67 mm	6 w/d (4 mm)	Undercut	Hard and soft species, artificial wood materials up to 60 mm thick. Very clean cut.
50 mm	12 w/d (2 mm)	wavy	Artificial wood materials up to 30 mm thick. Very thin cut.
50 mm	12 w/d (2 mm)	wavy	For cutting sharp curves in wood and artificial wood materials up to 20 mm thick.
75 mm	10 w/d (2.5 mm)	Undercut	Reverse tooth for sawing on the down stroke. For plastic-coated boards.
60 mm	6 w/d (4.5 mm)	--	The tips of the teeth are coated with tungsten carbide, especially good results when working with chipboards with a high content of adhesive mass.
70 mm	--	--	Semicircular flat and triangular files. For wood and artificial wood materials.

When purchasing, you need to pay attention to the height of the teeth. Small ones provide precise sawing, but work with the blade will be slow. Large ones will allow you to work quickly, but the cutting line will be 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 compiled as general recommendation to the choice of saw blade. Its basis is a formula indicating the number of teeth per inch of blade. If the marking indicates TPI 7, it means there are 7 teeth per inch.

• If it is necessary to make a longitudinal straight cut on 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, bits with medium sharp protrusions, t=3 mm, TPI 9 are suitable.
• For figured cutting - with small sharp protrusions, t=2 mm, TPI 9–13.

In order for the tool to vibrate less in your hands when working, it is better to choose blades that contain 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 less deviations from the cutting 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

To cut a strictly perpendicular line on a thick wooden base, it is necessary to use thick nozzles. The thinner the material, the thinner the canvas should be.

Mounting form

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

Marking features

Nozzle types:

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

From the markings 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 - from high speed steel. BIM - made of bimetal. HM - made of hard alloy.

For cutting plywood, soft-fiber wood, chipboard, chipboard with a thickness of no more than 30 mm, and plastic, it is better to choose HCS blades. The teeth of such files have a pointed shape and are conically ground. High flexibility prevents the possibility of breakage. HSS files are designed for cutting metals. They have a curvature at the bottom, which is necessary to prevent the metal from scuffing. These bits are thinner than wood cutting blades, but they are harder.

Bimetal tips are durable. They are made by laser welding. The basis is high-carbon steel. The back part is formed from it, the teeth are made of high-speed steel. The attachment is suitable for cutting curves and straight lines. NM blades are intended for sawing lightweight concrete, fiberglass, tiles.

For laminate and veneered boards, a sheet with reverse system teeth The cut occurs in the opposite direction, towards itself. This move allows you to process parts different lengths, get a clean line, without chips.

Manufacturer brands

Manufacturer only trademark BOSCH produces a wide range of attachments. Market share - about 90%. Electric jigsaws HITACHI, MAKITA and others also include many different saw blades, but the parts are made by third party manufacturers.

It is important to consider the power of the tool and the ease of mounting the blade in the holder. Professional jigsaws are sold in cases. The kits contain additional accessories.

Hand and jigsaws have long been adopted by home craftsmen. This is very useful devices, which will allow you to carefully and accurately cut almost any material of varying thickness and configuration. But before you begin the work, it is necessary that the correct jigsaw file is selected. However, immediately accept the right decision quite difficult. This is due not only to the large selection, but also to the huge number of types of fabric.

Some general information

If you have a jigsaw and no files, then it is a useless tool. If you have a whole set of files, then you can cut almost any material. There is no need to think that a jigsaw is designed to work only with metal or plastic products. Although we can say that it is quite advisable to have both manual and automatic tools, a little later you will understand exactly why. With proper skill, you can make straight and shaped cuts on chipboard, ceramics, metal, and so on. But you should understand that each type of material has its own 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 different thickness, density, hardness and other parameters, this imposes certain requirements on the quality of the blade steel.

Hand jigsaw files

It is quite logical that without a file you will not be able to complete 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 wood blade can be used for quick cutting. This is one of the most common and popular files. Its peculiarity is that such a blade can process a large amount 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 construction of buildings.

And here are the files for hand jigsaw clean cut allows you to get high-quality surface. This is achieved due to a 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 saws for laminate. They have a unique arrangement of teeth that leave no marks behind.

Blade for working with metal

It is one thing to process a material such as wood; it is quite another to process metal. Please note that the wood saw 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 distinguishing feature. The teeth are very fine, allowing you to work with sheets up to 6 mm thick.

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

Electric, benchtop and manual jigsaws

It is worth understanding 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 hand-held, then you should always have several spare files. This is due to their fragility. They really break down often and at the most inopportune moments.

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

Marking of jigsaw files

Special markings 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 important 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 HSS inscription indicates that the saw made of high-speed hardened steel. This is a hard, but at the same time quite brittle material that can be used to work with both aluminum and thin steel.

But the marking of jigsaw files BIM means that the blade is bimetallic. It is essentially a combination of HCS and HSS. This file has improved properties, but also high cost. The HM mark means that such a blade can be used for particularly hard materials, for example, sawing ceramic tiles etc. In principle, it’s 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 purchasing, you should always pay attention to the shank of the blade. Naturally, it has only one mount, unlike a hand 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 instrument. For example, the Makita company produces jigsaws with a mount that is fundamentally different from other models. There are specially cut circles on both ends various diameters. Naturally, you can’t put a file with a different type of fastening on a jigsaw.

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

Cloth for working with laminate

Today many people say that for processing parquet board or laminate, an exceptionally clean cut is required. Someone might recommend using almost a diamond-coated blade. However, the price for 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 that much.

So, it is not at all necessary to purchase an overly expensive instrument. Usually a blade is enough for a clean cut. Of course, there will be a chip of about 1-2 mm. However, in most cases, the laminate is covered with skirting boards, which are much larger than the chip. For this simple reason, do not overpay again. When buying jigsaw files 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 your purchase with a small margin.

Something about the shape of the teeth

The configuration of the blade teeth determines the capabilities of the tool. Large quantity fine 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 files can be divided into the following groups:

• Set (milled) - used for cutting soft materials such as wood and plastic, as well as non-ferrous metals. The routing ensures that excess heat does not accumulate, and sawdust is removed from the cut and the blade.
• Wave-shaped (milled) - used for clean cutting of aluminum, soft materials (wood, plastic) and non-ferrous metals. In this case, the setting is performed in groups, that is, several teeth in a row in one direction.
• With conical grinding (ground) - a good solution for obtaining a clean cut on wood and plastic. The non-working edge is ground. These are typical jigsaw files for laminate flooring.
• Ground, set teeth are one of the best solutions for rough cutting of wood, chipboard, blockboard, etc.

Width and thickness of the canvas

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 not only be stable, but also more durable, and will practically not deviate from the intended plane. Of course, this is also high-speed cutting, don't forget about that. At the same time, narrow files provide good maneuverability compared to wide ones. The arrangement of the teeth on the jigsaw drive axis 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 proper perpendicularity of the cut. In addition, the thicker the file, the higher its stability.

Something else

You probably know that the teeth of the blade must be harder than the material being processed. So, to carry out 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 blades for such purposes, which are 1/3 hardened steel and 2/3 high-carbon steel. The service life of such files is quite long, so they will pay off with interest. In addition, the risk of sudden breakdown here is much lower than in classic versions. But since choosing a file for a jigsaw is not difficult, and you already know how to do it, you will not have any problems selecting the appropriate bimetallic blade.

Conclusion

If we talk about manufacturers that have proven themselves well, these are the companies Bosch, Makita and Praktika. The 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 from these brands, and you will not regret anything. Do not forget that all files have their own purpose; using them for other purposes is unlikely to lead to the expected results. A jigsaw is a high-speed tool, so securely fasten the blade and try to work with safety glasses and gloves. Basically, we looked at the main types of jigsaw files. Now you know that there are blades for wood, metal, as well as combined blades for other materials. By paying attention to the labeling of the product and the method of its fastening, you will definitely make the right choice.

Today we will look at the types of files for electric jigsaw, because when choosing, the buyer has many questions. There are a lot of types of saws, because with a jigsaw you can cut not only wood, the list is much longer. Therefore, in this article we will figure out which saws are best for cutting simple wood, and which chipboard or fibreboard, which saws are used to cut various types metal

And of course, we will pay attention to the markings, so after reading this article, you will begin to understand which file is suitable for which work. It’s not for nothing that there are different letters and numbers on the files. What do they mean? We will analyze all this using the example of popular models from Bosch, since they 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 saw. Let's figure out what they mean.

The letter T means the type of fastening, that is, T-shaped (Fig. 1). There is also U, which 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 an A, for example T118A means a file with a T-shaped shank, short, very fine tooth. Next, respectively, B - a slightly larger tooth (most often these are saws with fine teeth for plywood, chipboard, fiberboard and wood for a clean cut). Files with the letters C and D - with the largest teeth, for rough sawing on wood.

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

• F - bimetal (the coolest, highest quality)
• R - with reverse tooth
• X - universal for wood, metal and plastic.
• O - for a curved cut (cutting a circle, for example, usually thin, so that the file can be turned straight while sawing).
• P - thick options for sawing strictly at the exact selected angle (thick, do not bend, so they cut perfectly). A prominent representative is the T144DP, which costs significantly more than the standard ones.

On wood

The main purpose of an electric jigsaw is cutting wood. There are a huge number of files for this purpose and they are all different. Let's go in order.

If you need to cut ordinary boards and the quality of the cut, its cleanliness are not important to you, you are working for speed (for example, cutting ordinary boards for firewood or for a fence), then buy jigsaw files with large teeth. 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 saw, since you won’t be able to cut a board or block 70 mm thick (for example) with a regular saw, you will need an extended one.

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

For a standard set of nail files, see the photo:

Well, now we’ll look at each file separately, what it can cut, and what kind of work it’s best suited for.

For metal.

T118A is a standard metal file, has a very fine tooth (like metal blades). You can cut metal up to 3 mm, but there is a terrible grinding noise, so use hearing protection. I highly recommend it. Also, due to the fact that the tooth is very small, it is also recommended to saw plastic with it; many finishers do this.

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

In addition to the standard metal file, there are special options for some other metal. For example, an aluminum file has a larger tooth, so the teeth do not clog. After all, aluminum is a soft metal, so the standard one for metal gets clogged with shavings very quickly.
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 tungsten carbide coating instead of teeth, which actually cuts any stone surface.

T150Riff - special for tiles, cost about 250 rubles. Excellent for cutting tiles.

It largely determines the accuracy and productivity of cutting material. Discussed in the article technical specifications files and the key differences between them will help you choose the right blade for various types works

A file for a particular job is selected in two ways: firstly, they are guided by the inscriptions, and secondly, they look at the size, teeth and setting.

Reading the markings

There is no single standard for alphanumeric marking of blades for jigsaws, but most manufacturers adhere to the European classification from Bosch or indicate it in addition to their own designations.

Explanation of markings

Files are made from various grades of steel, which influence the purpose of the blades and are indicated by logos:

1. CV (HCS) is an elastic alloy alloy for cutting wood, synthetic and wood-composite products.
2. HSS is a strong high speed steel for hard materials.
3. BM (Bi-Metal) is a compound of the first two grades of steel that can withstand significant loads and is suitable for many operations.
4. HM is a carbide for cutting tiles and building blocks.

The purpose of the canvas is also indicated by the following marks:

1. Wood - soft lumber, fiber boards.
2. Hardwood - solid wood, laminated panels.
3. Inox - stainless steel.
4. Alu - aluminum.
5. Metal - tin, profiles and pipes.
6. Plaster, fiber - fiberglass.
7. Soft-material - rubber, polystyrene, carpets.
8. Acrylic - plexiglass, polycarbonate.

Sometimes there is an inscription on the file that specifies the type of work:

• basic - standard blade for high-quality cutting;
• speed - saw with set teeth for quick cutting;
• clean - blade without markings for a clean cut;
• progressor - saw with different teeth for cutting various materials;
• flexible - flexible blade for cutting metal;
• special - for cutting ceramics, plastic and other special work.

We cut wood materials

Cutting wood and everything made from it is the main purpose of a jigsaw. Therefore, a larger range of saw blades are produced specifically for wood and are divided by type of work.

Fast cut

Certain construction work with wood do not require special care, for example, sawing bars for sheathing or dismantling old window frame. What is more important here is the speed provided by fast cutting blades with characteristic features:

1. Large teeth - up to 6 mm.
2. A fair amount of separation - about 1 mm.
3. Long blade - from 60 mm.
4. Width - up to 10 mm.

For thick workpieces, similar blades with large cutters are used, but without routing - they deviate less from the vertical. In principle, the thicker the file, the better it maintains perpendicularity.

Advice. A blade with an oblique tooth is better suited for cutting along the grain, and a blade with a straight tooth is better suited for a cross cut.

Clean cut

An operation such as pruning furniture board or parquet board, requires a smooth and precise cut. Such tasks are performed with less productivity, but with better quality, using blades for clean cutting that have:

1. Teeth less than 3 mm.
2. Minor divorce.

Most saw blades cut by retraction, so the material is placed reverse side. To mark and cut from the face, you need a blade with a reverse tooth. They are not very convenient to work with - in addition to maintaining the direction of the cut, they have to overcome the force of pushing out the tool.

Advice. A specialized saw with two rows of teeth allows you to cut panels laminated on both sides almost without chipping.

Curly cut

It is problematic to cut out small radii with a wide blade. Files for figured cutting have a beveled back side, making it easier to turn, they can be rounded without chipping and differ in appearance:

1. Small (up to 2 mm) tooth.
2. Narrow working part - up to 4 mm.
3. Small length - up to 40 mm.

We cut polymer materials

PVC pipes and window sills are sawn using blades on wood or metal with a large tooth. Fine-toothed saws are also suitable, but you will have to cut at a minimum speed, otherwise the sawdust will soften and clog the blade - it will no longer be sawing, but cutting with heated metal.

For thin plastics and plexiglass, a metal file with small teeth is suitable. For thick ones, you can take a wood blade, turn off pendulum mechanism and cut at low speed. Shaped sawing of polymer sheets is carried out with a narrow file on wood.

We work with metal

For cutting galvanized profiles and sheet metal products, wave saw blades are used, similar in profile to blades for hand hacksaw. They are distinguished by small (up to 1 mm) teeth, deflected not through one, but in groups of 3-5 pieces.

At permanent job take three blades: for steel, aluminum and for non-ferrous alloys. If you have to cut metal infrequently, then one steel file will be enough, which is also suitable for ebonite and textolite.

In general, a jigsaw is not suitable for sawing metal: the tool is heavily loaded, and the process is slow. Rather, this is an extreme method, justified only occasionally, for example, when cutting sandwich panels with bimetallic saws with small cutters at the edges and large ones in the middle.

Blades for specific tasks

Drywall and cement-containing materials quickly set any file, with the exception of specially designed blades with carbide tipped, which also cut thermal insulation well.

The hole in the tile is cut using a ceramic file without teeth coated with carbide. It is also suitable for working with glass fiber reinforced polymers.

The cutting part of the blades for cardboard, rubber and other soft materials is not made with teeth, but with polished waves or simply looks like a knife.

For sawing combined materials, special files are designed, one half of the blade of which is equipped with small teeth, and the other with large ones.

Advice. The length of the file is chosen based on the thickness of the material. To prevent the blade from tearing out or breaking, its end must extend out of the cutting line in any position of the jigsaw pendulum.

For household needs, a set of 5-10 files for various purposes is enough. Just starting to use a jigsaw, they acquire inexpensive kit, master the intricacies of working with different types of blades and, based on their own experience, select the necessary files. Still, there are no strict recommendations; often one canvas copes well with tasks that are atypical for it. Here you can experiment, but think first.

Most consumers purchase canvases at appearance, considering that the size of the teeth and the high cost of the product are the main criteria for selection. In fact, everything is not so at all, since there are more than 45 types of files, each of which is intended to solve specific task, and the cost will not always mean that the material is made of high-strength steel. In order to correctly determine the material of a product and its compatibility with a certain type of work, attention must be paid to the shank. There are abbreviation tips there.
Meaning "HCS". It means carbon steel, which is used only for woodworking, Chipboard materials and fiberboard. It is not used for metal, even if the teeth are too small - these are all devices for cutting wood. The tooth stroke is large enough to work with soft materials, many blades have flaring for quick cutting. But remember that the quality of the cut will deteriorate significantly in this case.

Meaning "HSS". If you see such a marking, then the file can be used for cutting metals - it is made of hardened high-speed steel. It can equally successfully cut soft and hard metals, suitable for sawing aluminum, cast iron, steel. The only drawback of such a product is fragility. Buy 2-3 pieces at once so as not to run to the store every 10-20 minutes.

The inscription "BIM". It means that the metal is suitable for cutting both wood and various alloys, and combines the qualities of the two groups described above. This group also includes a jigsaw file for tiles (marked “NM”). It is made of hard metals. Its cost is much higher than usual, so you don’t need to take it for woodworking - just throw away the money.

Marking T101AO. Hardened fine-toothed saw blades designed for high-precision metal cutting. As a rule, they are specific and are produced only for certain brands of devices. These, for example, are compatible with Bosch.

Other markings are rare and are only derivatives of these groups, so first we look at the letter markings, and then select the meaning of the numbers (small, medium, large tooth, etc.). We will look at how to choose the right teeth later in the article.

Canvas size

This is no less important indicator, which plays a big role when choosing a product. Metal files are made very short, since there is no point in processing material thicker than 0.5 centimeters. And such dimensions are no longer easy. In turn, the blade for a jigsaw for wood is much longer, since sawing beams up to 15 centimeters thick is a common occurrence at any construction site.

The width of the canvas also plays a big role. If you are working with chipboard or fiberboard, then it will be more convenient to use thick metal that can be easily removed from the groove. For figured cutting on wood, you should use only narrow jigsaw files, since they are much more convenient to turn. Naturally, tools of this type are also suitable for metal work.

Tooth sizes and shapes

It will be difficult to choose here, since there are many variations and each manufacturer is trying to introduce something new. And this “something” is not always better than previous models. But there is a pattern, and choosing is not as difficult as it seems at first glance. Let's consider in general outline, what types of files you can find, and then we’ll look at the details.

You need to choose a tool carefully, weighing not only these categories, but many other nuances that we described above. Even the smallest file may not be suitable for metal work, since its teeth will be soft and set for a wide cut of wood. Take this into account.
