Circular saws for wood are quite actively used both in production and in everyday life. They are indispensable where it is necessary to carry out the most accurate cutting of materials in a short time. Of course, to perform work using this type of tool you will need a saw wheel, and its selection must be approached with all responsibility. First of all, the correct choice affects the quality of the cut and, no less important, increases the level of safety of the work process. In order not to make a mistake in purchasing an important consumable item for a circular saw and to be confident in the successful outcome of its use, you need to familiarize yourself with the types and technical characteristics of cutting wheels, which we propose to do right now.

Features of cutters and criteria for their selection

Consumable discs for circular saws are available in a wide range, so there is no shortage of such an important cutting element in the retail chain. If necessary, you can easily select exactly the cutter model that will be compatible with the main tool and suitable for a specific type of work. Many inexperienced craftsmen are trying to find a universal circle that could simultaneously process various materials in all possible ways using different types of saws, but, unfortunately, such samples do not exist. Even if you can somehow adapt an unsuitable element for your purposes, the process is unlikely to be safe, and certain problems will arise with the quality of the cut. For example, a miter saw should be equipped with a wheel with a negative tooth angle, which will provide a clean cross-cut. If such a cutter is installed on a machine for longitudinal sawing of wood, it will increase the vibration of the equipment and push the workpiece, which threatens the operator with injury.

Types of cutters

Cutters, like any working tool, have a number of technical characteristics that indicate their size, purpose and material of manufacture of the product. So, first of all, it is worth noting that all saw blades for circular saws are usually divided into two groups:

monolithic;
carbide.

In the first case, we are dealing with products made from solid metal, which is high-speed or high-carbon steel. Longitudinal and transverse sawing of soft and hard wood involves the use of discs with sharp teeth, similar to a hacksaw. Wide cutting segments with a curved configuration are formed on circular saws specifically designed for processing soft wood. Monolithic blades, usually containing many teeth, can be re-sharpened several times, since they wear out quickly enough and require sharpening from time to time.

Carbide saw blades for various woodworking are made from hardened steel, onto which, according to technology, it is customary to solder inserts made of tungsten carbide and cobalt. Saw blades with carbide tips are deservedly popular among customers, as they have a number of advantages over products without tips:

suitable for cutting all kinds of building materials;
there is no need to set the teeth;
are characterized by high strength;
show reliable operation;
don’t get stupid for a long time;
form a clean cut;
operate at high speed;
are presented in a wide range, which allows you to select the required type for various tasks.

If we talk about the disadvantages of such cutters, then they are the high price of carbide discs and the difficulty of re-sharpening them. So, to correct the cutting element you will need special machines and an experienced craftsman.

Size

The overall dimensions of wood saw blades are determined by the outer diameter and the size of the mounting hole. The outer size of the cutter must match the same parameter of the circular saw casing, otherwise the large circle simply will not fit under the small protective element. It is better to avoid small-diameter saw blades when installed on large circular machines, as this can lead to undesirable consequences. Also, the depth of cut depends on the outer diameter of the cutter and, accordingly, the thickness of the workpiece being processed is adjusted. It is worth remembering that the load on the circular motor increases in proportion to the immersion of the disk into the lumber.

The inner diameter of the saw blade should allow the cutter to fit snugly onto the seat pin, which will ensure a strong and secure fit. Manufacturers of working equipment produce cutting elements with different internal diameters. As a rule, the standard parameters of the internal part of the saw blade are 16, 20, 22, 30, 32 and 50 mm. There are also samples with a mounting hole diameter of 25.4 and 50 mm, with the second option provided for a cutter with a diameter of 250 mm. Some models have additional notches designed to improve the fit of the wheels on narrow pins.

For a hand saw, a circle is usually purchased, the outer diameter of which varies between 130 - 250 mm. Wood cutters 165x20 mm, 165x30 mm, 190x30 mm, 210x30 mm, 200x32 mm or 250x30 mm are often found here. Stationary machines are equipped with cutters with an outer diameter of 250 to 500 mm. In this segment, disks with a fairly large diameter (400x50 mm) are especially popular. A miter saw, as a rule, is equipped with discs from 200 to 305 mm, and mini saws (rotorizers) are equipped with elements with a diameter of 85 mm. For mini saws, circles of size 85 x 20 mm or 85 x 10 x 1.6 mm, 85 x 10 x 1.0 mm are most often purchased. If we talk about trimming, cutters measuring 305 x 30 mm and 305 x 32 mm are especially popular here. In any case, circular saws are accompanied by instructions that indicate the recommended cutter size, so when choosing blades for a wood saw, you can be guided by these data.

Number of teeth

Based on the number of cutting segments, saw blades for wood can be divided into three categories:

10-40 pcs. - small amount.
40-80 pcs. – average quantity.
80-90 pcs. - a large number of.

This parameter is selected taking into account the nature of the work performed. So, for cross-cutting wood, it is better to purchase cutters with the maximum number of teeth. Longitudinal sawing will be of better quality if it is carried out with a disk with an average number of cutting segments.

Shape and inclination of teeth

The configuration of the cutters has the most direct influence on the quality of the cut, and their shape must be selected for the specific material to be processed. The most popular is the variable-tooth saw blade, which copes with cutting both soft and hard wood, and also has an optimal price-quality ratio.

The inclination of the tooth is determined by the direction of deviation of the cutting edge relative to the blade. A negative inclination angle indicates a deviation of the tooth towards the back of the cutter, a positive angle indicates in the opposite direction. The standard tilt is 5-15°, positive – 15-20°, negative – 0 – -5°.

With a positive inclination of the cutters, the disk, as it were, grabs the lumber and runs over it during the sawing process, which helps speed up the processing of the material. In the case of a negative bevel, we are talking about a slow cut, but the cut or groove will be more accurate. The zero bevel circular saw blade is designed for cutting metals. As for the shape of the cutters, there can be many options, and it is the configuration that determines what kind of work will be performed.

The replacement tooth has an alternately beveled tip on the left and right sides. This type of cutter is suitable for longitudinal and cross cutting of wood and wood products. Unfortunately, such discs wear out quickly and are difficult to sharpen. Samples with flat trapezoidal teeth are more wear-resistant, so they are used for cutting dense metals. To cut laminate and similar materials, purchase a saw blade with two types of teeth: concave and triangular. If you need to quickly longitudinally and cross-cut wood, the choice is usually made on wheels with combined teeth (two beveled and one flat). If you plan to make rip cuts in formwork wood where contact with nails or concrete may occur, buy a blade with flat teeth containing a bevel, which will improve the quality of the work.

Blade thickness

First of all, the thickness of the disk determines the width of the cut, and the standard parameter here is 3.2 mm. For dense materials, craftsmen purchase standard or thicker circles. A thin wood saw blade is suitable for working with delicate wood. For aluminum products and laminated material, samples with a thickness of 3.2 mm or higher are recommended. By the way, thin specimens leave less waste, but they are less durable and wear out faster, so they have to be replaced more often. Thick cutters have a long service life, but their cutting is not so neat.

Disc design and markings

Good blades for sawing machines or circular saws are made using the laser cutting method, they are balanced on computer systems and ground using the latest technology. If, upon inspection of the disc, unevenness and roughness are noticeable, then it is better to refuse such a purchase. The thing is that such samples are subject to excessive heating, and their cutters quickly become dull. Compensatory cooling cuts must be applied to the circle blade, at the end of which a special groove is formed. Such additional elements reduce noise levels, reduce vibration and prevent the disk from overheating.

The branded circular saw blade is always marked not with paint, but with a laser, and even after intensive use, the printed symbols do not wear out, because information from the manufacturer may be needed not only at the time of purchase, but also during maintenance. Typically the markings carry the following information:

circle thickness;
diameter of outer and inner edges;
number of incisors;
rpm value;
tooth shape diagram;
serial number.

Having examined the characteristics of circular saw blades, we were able to come to the conclusion that when purchasing a cutting element, in addition to the main parameters, it is necessary to take into account what type of cutting will be carried out (longitudinal or trimming), what materials will be processed, and what type of equipment the saw wheel will be installed on ( miter saw, machine, mini circular saw).

The best manufacturers

All manufacturers of circular saws produce components for them, including saw wheels. Below is a short rating of the brands and models of wheels that are most popular among craftsmen.

Bosch Construct Wood 190x30 (from 650 RUR) - designed for fast and high-quality cutting of wood in difficult conditions. Not afraid of contact with nails and concrete.
Makita 190x30 (from RUR 1,000) – installed on cordless circular saws, characterized by a long service life and excellent quality of wood cutting.
Werk 190x30 (from RUB 200) – with carbide tipping, it does an excellent job of cutting wood of varying hardness, plywood, chipboard, etc.
Metabo Power cut 250x30 (from RUR 3,000) – performs coarse and medium longitudinal cuts and can be used on miter saws, as well as low-power circular saws.
HAISSER 250x30 (from RUB 700) – with carbide brazing and variable teeth, suitable for installation on professional equipment and can work without interruption for a long time.
DeWalt DT4287 250x30 (from RUR 4,500) – with trapezoidal teeth, shows high reliability when working with complex materials. For reliable fixation, the wheel is equipped with a honed clamping hole.

It is rare to meet a craftsman who is not involved in sawing wood. A circular saw, a circular saw, a miter saw, an angle cutter are present in garages and home workshops almost everywhere, which means that when saw blades for wood are needed depends only on time. All blades differ from each other in the material of manufacture, shape, size, tooth pitch and other important parameters on which the quality of the cut largely depends.

Saw blades

Today, manufacturers offer a fairly large range of equipment for wood processing. When purchasing it, you need to pay special attention to the selection of the cutting blade, because it determines what kind of material you can work with.

Wood saw blades for grinders and circular saws differ in their technical characteristics. Their teeth are inclined in the direction of movement, and the more of them there are on a part, the more accurate and accurate the cutting itself will be.

For an electric hand saw for cutting boards, fiberboard, you will need a knife with fine teeth (about 100 pcs.). For cutting wood with many knots, reinforced discs with 24 cutting edges are selected.

The marking of saw knives consists of 2 numbers. The first means their diameter, and the second characterizes the diameter of the landing rod. Discs that have a lower rating than that provided by the saw cannot be installed on the equipment, since between the part and the casing there will be a space into which a hand can accidentally get caught.

How to choose the right disk

When purchasing saw blades for wood, you need to pay attention to the following parameters:

for what types of work they will be used, what kind of wood will be cut;
disk series, which takes into account the shape and size of the teeth, whether there are special plates;
the design of the saw blade itself (tooth shape, slope, presence of plates, their shape, location, blade thickness);
the outer diameter must be selected taking into account the rotation speed;
diameter of the mounting hole, which depends on the type of tool;
parameters of teeth (thickness, shape, number, etc.).

Disk characteristics

When choosing a circular saw and saw blades for wood, you should immediately decide what materials will be processed and what work the tool is needed to perform. Today there is a wide range of models on sale. All of them are designed for specific jobs, so their selection should be given special attention.

Dependence of disk diameter on equipment rotation speed

Saw blades for wood can have different sizes.

disc diameter up to 80 mm is used at a rotation speed of 23,800 rpm;
up to 100 mm - at a rotation speed of 19,100 rpm;
up to 120 mm - at 15,900 rpm;
250 mm - at a rotation speed of 7,600 rpm;
disc diameter 300 mm is used at 6,300 rpm.

It should be remembered that the larger the diameter of the blade, the lower the rotation speed of the saw. This must be taken into account when choosing equipment.

Dependence of cutting speed on material

In this regard, there is the following pattern:

for soft wood, it is recommended to use a speed of 50-90 m/s;
cutting of hard rocks occurs at a speed of 50-80 m/s;
cutting exotic types of wood - at 50-85 m/s;
for MDF panels the speed is 30-60 m/s;
for laminate panels - 40-60 m/s;
for simple carpentry work and chipboards - 60-80 m/s.

When choosing a tool, it is necessary to take into account that saw blades for wood have different sizes and shapes of teeth and can be used at several operating speeds.

It should be remembered that all tool manufacturers indicate the required parameters, so you can easily decide which equipment you need to choose to complete the planned work. In addition to speed, speed, thickness and other indicators, it should be taken into account that circular saws can be not only hand-held, therefore, first of all, you should determine for which tool a particular disk is intended.

Why is it important to choose the right saw blade?

When deciding how to choose a saw blade for wood for a clean cut, you need to take into account parameters such as the shape and size of the teeth. Manufacturers offer several models:

Carbide, with special soldering, which provide cross-cutting. The products can be used for solid wood. Use a wood saw blade for a clean cut when cutting wood fibers, chipboards, hard and soft wood. The teeth of such models are trapezoidal in shape and made of hard metals. Carbide discs with thick scoring knives ensure greater working speed. They are used for machines with automatic material feeding.
Special saw blades for wood with variable teeth, scoring knives, thickness reduced for cutting. Used only for longitudinal cuts, they allow you to make a neat and thin cut. Such cloths cannot be used when working with poplar. The tooth shape is variable, inclined by 10°, straight. Such discs are used for single-shaft or double-shaft multi-rip machines and are used for soft and hard wood with a moisture content of up to 15%.
Disc with variable teeth, which can be used for radial, pendulum cutting. Suitable for hand tools. Provides high-quality cross-cutting of solid or hard, dried or wet wood. The tooth has a negative external angle, the inclination of which is 15°. A similar saw blade for wood, the price of which is from 114 rubles. - the most optimal option for construction work on the site.

There are many jobs where you can't do without a circular saw. But this alone will not be enough; you need a high-quality saw blade. With proper use, a good cutting part will serve the owner for a long time and will ensure comfortable use of the tool. Depending on your goals and objectives, you need to have an assortment of equipment of the required sizes and other requirements. In this article we will briefly look at the types of saw blades, what you should pay attention to when choosing.

How to choose circular saw blades

There are many tasks that a circular saw can handle. But, unfortunately, one saw wheel cannot be used for the entire range of work. It is necessary to take into account a number of factors in order to correctly select the necessary part and achieve the task assigned to it. Starting from sizes, ending with the number of teeth and material. An illiterate choice can lead to tool failure and sometimes even an accident.

When choosing, pay attention to the technical characteristics of the circular, and based on this, you need to select a suitable circle. Some of them increase the load on the motor and may not be suitable for your tool.

Dimensions

Much depends on the type of circular saw you have - everything is indicated in the instructions. But there is also a dependence on the type of work - what material will be processed.

External diameter. Selected according to the size of the protective casing.
Inner diameter. Depends on the size of the power shaft of the circular.
Number of teeth. A large number of teeth has a bad effect on cutting speed and load on the engine, but the quality and cleanliness of the cut increases.
Tooth inclination. Most often, wheels have a positive tooth angle, which is good for longitudinal cutting.
Thickness of the circle and soldering. Determines how thick the cut will be. With a larger width, strength increases, but the load on the engine increases.

Marking of saw blades

Usually, high-quality products are marked with a laser. Based on the marking data, you can obtain information about the thickness of the blade, external and internal diameters, number of revolutions, number of teeth.

For example, a disc with values of 190 x 1.8 x 20 mm means that the disc has an outer diameter of 190 mm, a solder thickness of 1.8 mm and a circle thickness of 20 mm. Solder thickness is a key factor when choosing a disk. Moderate thickness will not overload the gearbox, which will ensure the longevity of the tool. This blade is well suited for cutting 40 mm boards.

Material

The material for the discs is high-speed steel, sometimes chrome vanadium steel. This steel is alloyed with molybdenum, tungsten, vanadium, and chromium, which significantly increases the strength characteristics. Marking – CV or HSS.

Carbide saw blade

High speed steel is strong enough, but for some types of work this is not enough. Then carbide materials marked TC are used. The disk is half made of chrome vanadium steel, and the teeth are made of tungsten carbide, which are soldered onto it.

Diamond circular saw

For cutting stone, concrete and other durable materials, diamond-tipped discs are used, which are attached by laser welding. One of the most durable types of discs, allowing you to cope with high-density materials.

Steel blade for circular saw

Such wheels are widely used when working with metals and alloys. To avoid overheating, water cooling is used. If it is not provided, the disks are equipped with holes to reduce surface heating.

Circular saw for stone

The most commonly used saw is the one with diamond segments described above. There are discs for dry and wet cutting of stone. To avoid overheating when working in dry mode, the circle is equipped with holes, and the work itself is carried out intermittently.

When wet sawing, the discs are made without teeth, and diamond brazing is present along the entire edge.

How to choose a saw blade for wood

For wood, high carbon steel with few teeth is a good choice. Pay special attention to the solder thickness. It should be moderate, ranging from 1.6 to 2 mm. This thickness ensures good cutting without putting extra stress on the circular saw motor. It is important what type of wood we cut: hard wood, coated soft wood, laminate or other wood products.

Conclusion

It is worth taking a responsible approach to choosing a circular saw blade, taking into account the design features of the power tool and clearly formulating the task. This way you will ensure comfortable work and keep your saw much longer. And, of course, do not forget about safety precautions; perhaps this is even more important than the selected part.

It is difficult to imagine construction work without cutting any materials. At home, in the country or on a personal plot, you cannot do without an automatic saw. With proper equipment and use of equipment, labor productivity increases significantly.

An important element of any saw is the disc. The correct choice of this consumable material determines the speed and quality of product processing, the amount of defects and waste, as well as the safety of the performer and others.

Is it possible to choose a universal saw blade?

Choosing a saw blade is almost a science. At the same time, many parameters should be taken into account and the characteristics of different models should be compared. If you have no experience, then it would be better to seek advice from a specialist. At the same time, it is not always possible to get the really necessary information from saw blade sellers. It is better to entrust the choice to a professional who has the skills to cut various materials on a circular saw.

Why is it so important not to make the wrong choice of disk? First of all, a competent approach to purchasing is required for safety reasons. Circular saws occupy a leading position in the number of accidents at work. Such statistics can be changed if each performer and organizer of construction work takes a more responsible approach to the question: “How to choose the right saw blade?”

Some are trying in every possible way to save on consumables and are looking for “universal” saw blades. But, in fact, there are none. It is impossible to choose a saw blade that would perform equally well in cutting hard/soft wood, metal or various composites. The disk is selected to solve a specific problem. Of course, this approach involves an increase in the cost of work, but this is justified by an increase in speed, quality and safety.

For example, blades with negative tooth angles fit under miter saws and provide clean cross cuts. But they cannot be used for sawing tables (longitudinal cutting) - such discs create the effect of “repulsion” of the workpiece, increasing vibration and resistance of the material. Saw blades with teeth at a negative angle usually have small interdental spaces and a large number of teeth. Sawdust quickly gets clogged into these recesses, which increases the load on the engine.

Basic criteria for selecting disks

The cutting tool has certain characteristics, dimensions, purpose, parameters and properties of the material from which the disc is made.

So, what criteria should you pay attention to?

Disk type. All saw blades are divided into two categories: solid and carbide.

Monolithic saw blades are made of solid metal - high-carbon or high-speed steel. Cutting tools of this type can have two configurations:

the teeth are sharp like a hacksaw - suitable for cross/longitudinal finishing cuts in soft and hard wood;
curved teeth with a wide back - suitable for working with soft wood.

The disadvantages of monolithic disks include:

dull quickly enough;
require periodic teeth setting and sharpening.

The disc blade can withstand several resharpenings. Usually monolithic specimens have many teeth. An additional advantage of the discs is their affordable cost.

Carbide saw blades are considered more reliable. They are made of durable tool steel. The discs are reinforced with soldering containing a high amount of cobalt and tungsten carbides. These discs are most in demand due to a number of advantages:

allow cutting many building materials;
there is no need to set the teeth;
reliable and durable;
the period of work from sharpening to sharpening is significantly higher than that of their monolithic counterparts;
the result is a cleaner cut;
high cutting speed;
The construction market offers a wide range of discs for performing various tasks.

However, two disadvantages should be noted:

difficulty of sharpening - special equipment is required;
relative high cost.

Outside diameter. This parameter is determined by the internal size of the saw casing. A blade with large dimensions simply will not fit on a saw with a small diameter protective casing. Using a diameter that is too small may have undesirable consequences.

The outer diameter directly affects the cutting depth. The cutting speed does not depend on this parameter. For hand-held circulation saws, the dimensions of the cutting tool are about 130-250 mm.

Important! The more the disk blade is immersed in the material, the more significant the load on the engine. The optimal protrusion of the teeth above the material being cut is no more than 10-20 mm.

Inner Fit Diameter. An important safety condition is the strong fastening of the “cutter”. The saw blade must fit tightly onto the seat pin.

Typical bore diameter dimensions: 16/20/22/30/32 mm. Some models of discs are equipped with additional side recesses for narrow pins to enhance fixation.

Number of teeth. All types of saw blades according to the number of teeth can be conditionally classified into three groups:

80-90 pcs. - a large number of incisors;
40-80 pcs. - average number of incisors;
10-40 pcs. - small number of incisors.

The choice of this parameter depends on the tasks at hand. For cross cutting, it is better to use discs with the maximum number of teeth. Longitudinal cutting is best done with a “cutter” with a small number of teeth (up to 60).

Shape of teeth. The configuration of the cutters has a significant impact on the quality of the cut. The shape is selected according to the material that is being breaded. The most popular wood saw blade with variable teeth - they are suitable for cutting any type of wood and have an optimal price/quality ratio.

Tooth inclination. This criterion is determined by the deviation of the cutting edge surface from the radius of the saw blade. A negative inclination angle is a deviation towards the back side of the tooth blade. Positive - deviation in the opposite direction.

The angle of inclination of the tooth is divided into:

5-15° - standard tilt;
15-20° - aggressive (positive) tilt;
from 0° to -5° - normal (negative) deviation.

Teeth with a positive inclination are recommended for longitudinal sawing - during the cutting process, the material is captured and the disc hits the workpiece. This speeds up the overall cutting of the workpiece. A negative bevel slows down the work process somewhat, but leaves a clean cut. Saw blades for metal have teeth with zero inclination.

Thickness of the canvas. The parameter depends on the operating mode and determines the width of the cut. Typical size - 3.2 mm.

A thin blade is more often used for cutting valuable types of wood. A standard and thicker saw blade is suitable for rougher materials. Blades with a thickness of 3.2 mm and more have saw blades for aluminum and laminate.

When discussing how to choose a saw blade, you should remember that thin blades use material sparingly, but are less strong and durable. Thick discs have a longer service life, but make less accurate cuts.

Disk design. The disk surface itself can provide the necessary information about the quality of the product. A good disc is made by laser cutting, computer balanced and ground separately. Signs of such processing are noticeable if you look at the disk in the light. The marks from the grinding tool radiate in circles from the internal hole - this means that the “cutter” was ground, balanced and calibrated after cutting the metal.

Advice. If the discs show signs of rough processing and roughness, then it is better to refuse to purchase it. Such a specimen will become very hot during operation, and the teeth will quickly become dull.

The disk blade must contain compensation temperature slots. There are grooves at the ends of the slots. These elements reduce saw noise, harmful vibrations and the heating temperature of the blade itself. Rounded holes at the moment of loading under the primary dynamic pressure of the teeth reduce the risk of blade breakage.

Fabric marking. Manufacturers of high-quality discs mark their products with a laser, not paint. The inscription should not be erased after long-term use of the saw blade, since the information contained may be needed not only during purchase, but also during maintenance.

The disc label displays:

thickness of the canvas;
outer/mounting diameter of the disk;
number of teeth;
number of disk revolutions;
tooth configuration icon;
disc series.

Important! The permissible number of disk revolutions must exceed the maximum permissible speed of the saw spindle.

How tooth configuration affects cutting quality

There are many variations in tooth shapes. All of them are designed to perform a specific task:

Saw blades for wood: features of choice

When choosing a saw blade for wood, you need to take into account additional parameters:

type of working tool used: angle grinder or circular saw;
cutting: longitudinal or transverse;
thickness of processed wood;
wood species

Depending on the material, the optimal sawing speed is selected:

50-90 m/s - soft wood;
50-80 m/s - hard wood;
80-85 m/s - exotic tree species;
60-80 m/s - joinery wood, chipboard;
40-60 m/s - laminate panels with one- or two-sided coating;
30-60 m/s - MDF.

Additional tips:

Carbide discs with scoring knives are used for machines with automatic wood feeding.
Discs with variable straight teeth, inclined 10°, are used for two-shaft and single-shaft machines if the wood moisture content is no more than 15°.
Discs with variable teeth with a negative angle are suitable for hand tools. This option provides high-quality cutting (transverse) of solid wet or dried wood.

Review of popular saw blade manufacturers

A wide range of saw blades is offered by domestic and foreign manufacturers. The products of the following companies are in particular demand: Makita, Bosch, Zubr, Freud, Intertul, Werk, etc.

Corporation Makita(Japan) has specialized in the manufacture of power tools and components since 1915. The company has branches for production, sales and service in more than 100 countries. All products are distinguished by durability, accuracy and ease of use.

Makita saw blades are available in 13 different categories. Main types of disks:

MFors - double beveled tooth equipped with a clear M-shaped cutting edge;
MacFors - discs designed for different models of hand saws;
MacBladePlus - the blade has a special coating that provides smooth cutting, low friction and effective protection against resin and corrosion;
specialized blades for cordless saws;
disks for wood with nails and knots;
metal cutters - in particular for stainless steel, aluminum;
special discs for circular saws;
saw blades for composite materials, multilayer panels;
discs for laminate.

Saw blades demonstrate high performance and proven quality Bosch. Tools are divided into four groups:

Russian manufacturer " Bison» supplies the domestic and world markets with a wide range of high-quality tools and accessories, including saw blades. The company has developed 8 series of discs. Of these, 4 groups are “Master” categories and 4 are “Expert” categories.

Saw blades "Master":

“Quick cut” - for rough rough and very fast cuts of wood;
“Optimal cut” - clean and fast cuts of chipboard, MDF, adhesive boards, plywood, hard/soft wood; tooth shape - ATV cutters with variable angle;
“Clean cut” - provides smooth cuts in wood, adhesive boards, chipboard and MDF, lined with plastic, veneer, paper or film;
“Precise multi-cut” - the saw blade is designed for working on laminate, aluminum, plastic and non-ferrous metal; shape - TCG teeth with negative slope.

Freud saw blades have the following properties:

cloth with hardness 45 units. (Rockwell scale);
compensation slots are laser cut;
discs are made of special hard alloy;
Tri-metal solder technology was used in production;
presence of a tension ring;
The saws underwent dynamic balancing, as well as control of runout in the axial and radial directions.

When buying a saw blade, be sure to take into account the characteristics of a circular saw:

maximum speed;
engine power;
internal size of the protective casing;
mounting size on the motor shaft.

The choice of tooth configuration depends on the engine power. A negative slope and a large number of teeth will create a significant load on the engine - the equipment will have to operate in “peak” mode, which is extremely undesirable.

Spindle speed and revolutions are related to the size of the saw blade. When purchasing, you should check that these parameters meet the requirements specified by the disk manufacturer.

It is not advisable to use discs for pendulum miter saws for circulation and hand-held machines. If the level of axial or radial runout of the machine is high enough, then you should not install an expensive disk on it.
