Disc for circular on wood which one to choose
Such circles stand out for their strength, so they are very often used not only for working with wood, but also with harder raw materials. And also this type stands out for its long service life, in comparison with monolithic products. A distinctive advantage, which determines a high degree of wear resistance, can be considered the presence of cobalt and tungsten solders on cutters of different configurations. Such discs also become unusable, but the principle of the design of the elements does not allow restoring the discs after operation. In addition, carbide wheels stand out for their high cost.
How to choose a Circular Saw Blade
Number of teeth
Too many teeth will put additional stress on the motor and may also slow the cutting speed. If you use consumables with fewer teeth on the surface, it will be easier to remove chips from the working material, but the cleanliness of the cut will be imperfect. Based on this parameter, disks can be of the following types:
- discs with incisors, the number of which will be in the range of 80–90 pieces;
- products with average values, where the number of teeth will be in the range from 40 to 80 pieces;
- cutting discs with a minimum number of cutters ranging from 1 to 40 pieces.
Products with average values belong to the universal class, therefore they can be used for processing different types of wood and wood-containing materials.
Choosing circular saw blades for wood
Today, in the arsenal of home craftsmen and professional workers in construction and repair specialties, there is a large number of different tools for working with wood. This list contains a circular saw. a tool with which you can perform many different tasks. However, the fundamental question before starting operation is the choice of the cutting blade for the device.
Products belonging to this group are recommended for working with all types of wood, and they can also be used for cutting soft raw materials such as polymer alloys. High-carbon steel is used for the production of wheels. Among the positive features of the products, it is worth noting the affordable cost of the disks, they are quickly and easily sharpened, so the consumable material in most cases can be restored even after long-term use. Among the disadvantages of products, the low strength of the material stands out, which leads to rapid wear of the elements.
Features of the
With just one purchase of a powerful circular saw, the issue of using the tool for household and professional purposes does not end, since the device will need good consumables to complete the tasks. This applies to discs that will help to perform high-quality cutting or sawing wood and wood-containing materials. One circle for operating a circular saw will not be enough, since each type of cutting element has a specific function. Wood is considered a fairly popular raw material, which is used in many repair, industrial and construction works, therefore circular saw blades for wood can be used for different types of wood.
A distinctive feature of cut-off discs is also considered the ability to cope with cutting polymers, plexiglass and soft metals.
Circular saw blades differ in their performance, resource characteristics, as well as in the allowable number of regrinds. In addition, the discs can have different inner and outer diameters, as well as a different number and configuration of teeth. Maintenance of disks, as a rule, is carried out in specialized workshops; under normal conditions, these manipulations will be ineffective. It is worth noting that even the most durable saw wheel can be damaged if the tool is used for other purposes, therefore, during operation, work should be done only with the recommended type of raw material, in addition, thoroughly approach the issue of the intensity of use.
During the selection of parts, a number of fundamental parameters of the products should be taken into account.
In this case, you must first familiarize yourself with the instructions for the tool. Saw manufacturers indicate this information in the characteristics that a particular device has. As for the outer diameter, its choice is based on the dimensions of the protective casing in the circular saw, therefore, a cutting wheel with a large outer diameter cannot be placed on a device with smaller dimensions in the mechanism. The most common disc sizes are in the range 120–250 mm. This criterion is not responsible for the intensity of the cut, but is of great importance for the depth of cut.
And the inner diameter influences the power shaft of the tool. It can be of the following sizes. 16 mm, 20 mm, 22 mm, 30 mm, 32 mm. The size of the blade must match the size of the shaft in the saw. In modern models of equipment for fixing circles, there are special holes that allow you to fix the part with pins.
Most of the blades for circular saws for wood are made with a positive inclination, which increases the quality of the longitudinal cut. With a negative tilt angle, the radius of the tooth will be directed towards the back of the disc. However, longitudinal types of cuts are most often performed by products with a positive deviation of the tooth from the radius, since such a configuration provides a more reliable grip of the raw material. Slope classification is based on the following principle:
- an angle of 5 to 15 degrees is considered the standard incisor arrangement;
- the positive slope is within 15–20 degrees;
- negative. from 0 to 5 degrees.
Based on these values, it will be easier to find the consumable for the job.
Circular disc working principle
All electrical wood processing machines work on the same principle. The circular disc for wood is fixed on the axis of the motor, which gives it a powerful rotation. The tool is divided into several groups:
These systems differ only in their design. Rotation of the disk in a hand-held apparatus is carried out mechanically. Electrical devices require an electric motor. To adjust the cutting depth, as well as adjust the desired angle of inclination, all systems have a special platform.
The industry produces original mini-saws equipped with a battery. Such a cutting machine for wood, the disc mechanism of which is not very powerful, can be operated in areas where there is no electricity supply.
Varieties of electric tools
A wood processing device belongs to complex systems that are:
- Household. Low power allows you to cut a small amount of material.
- Semi-professional. The mechanisms are more powerful. However, its value is much lower than professional systems.
- Professional. These devices are capable of working for a long time in extreme conditions. Their versatility has found application in the construction industry.
Features of cutters and criteria for their selection
First of all, the thickness of the disc forms the width of the cut, and the parameter of 3.2 mm is considered standard here. For dense materials, craftsmen purchase standard or thicker circles. The thin wood saw blade is suitable for cutting delicate wood. Samples with a thickness of 3.2 mm or higher are recommended for aluminum products and laminated material. 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 life but are not cut as cleanly.
Choosing Circular Saw Blades. Ace Hardware
Number of teeth on a disc
Affects parameters such as cutting speed and cleanliness. With a decrease in the number of teeth, the processing speed increases, the conditions for chip evacuation are improved, but the cleanliness of the cut deteriorates. With an increase in the number of teeth, the cut is cleaner, but the load on the engine increases. Conventionally, according to the quantitative ratio, the disks can be divided into three groups:
- a large number of incisors is in the range of 80-90 pieces;
- average quantity (40-80 pcs.);
- small amount (10-40 teeth).
Discs with an average number of incisors are referred to as the universal type. They can process soft and hard wood, perform transverse and longitudinal cuts, use for processing various wood products.
In the first case, we are dealing with products made of solid metal, which is high-speed or high-carbon steel. Ripping and cross-cutting soft and hard wood involves the use of sharp-toothed discs, similar to a hacksaw. Wide cutting segments in a curved configuration are formed on circular saw blades specially designed for cutting soft wood species. Monolithic blades, usually containing many teeth, can be re-sharpened several times, as they wear off rather quickly and require sharpening from time to time.
Carbide saw blades for various woodworking are made from hardened steel, on which, according to technology, it is customary to solder tungsten carbide and cobalt carbide inserts. Saw blades with carbide taps are deservedly popular with buyers, as they have a number of advantages over products without soldering:
- suitable for cutting all kinds of building materials;
- there is no need to set the teeth;
- are highly durable;
- show reliable performance;
- do not dull for a long time;
- form a clean cut;
- operate at high speed;
- represented by a wide assortment, which allows you to select the required type for all sorts of tasks.
If we talk about the disadvantages of such cutters, then this is the high price of carbide discs and the complexity of their re-sharpening. So, in order to fix the cutting element, special machines and an experienced craftsman will be required.
Depending on the type of disc, the following can be processed:
- wood of various species;
- wood products. sheets Chipboard, OSB, plywood, laminated flooring and other similar materials;
- polymeric substances and products from them, for example, organic glass, polystyrene;
- natural stone material such as marble;
- soft metals. aluminum, copper alloys;
- products based on iron alloys. pipes, corrugated sheets, etc.
The cutting tool has certain characteristics, parameters, dimensions, purpose, properties of the material from which it is made.
Recommendations for choosing a disk
When choosing a blade, you must take into account the technical parameters of the circular saw:
- engine power;
- maximum number of revolutions;
- fitting size on the motor shaft;
- inner diameter of the guard.
Engine power affects the type of disc. negative angle, a large number of teeth create a large load on the engine, which will have to work in “peak” mode.
The number of revolutions or speed of rotation of the spindle is interrelated with certain dimensions of the disc, which the manufacturer recommends to use. Installation of a cutting tool with deviations from the recommended ones can lead to abnormal operation, as a result of which damage to the blade, saw and damage to the processed material is possible.
The seating dimensions of the blade (inner diameter) and the corresponding one on the motor shaft must match, otherwise the tool cannot be installed on the saw.
The outer size of the blade cannot exceed the inner size of the casing. if this parameter is violated, the tool will not be installed on the saw.
The disc type is influenced by a number of factors:
How to Select Table Saw Blades: Woodworking for Beginners #2. Woodworkweb
- type of work carried out, processed material;
- device, design of the cutting tool;
- number of teeth, their design.
Work performed and processed material. Since the discs are produced differently, it is necessary to decide on the types of operations (what types of cuts will be carried out), and also take into account what the cutting tool will handle.
Depending on the type of operations and material, the type of disc is selected: monolithic or with carbide taps.
The processing mode and type of material determine the number of teeth, their type and inclination. Most popular medium number of positive trapezoidal teeth.
A saw blade for a circular saw should be chosen taking into account the type of cut. it is possibly transverse along another longitudinal. Already today, an important role is played by the materials that you intend to cut. wood, plastic, chipboard, non-ferrous metals, pipes Let’s note one thing. any series of discs is designed directly for certain jobs.
The quality of the blade has a direct impact on the cutting efficiency. Not a bad canvas is created by means of laser cutting, while balancing is done on a computer. Grinding of each disc is done separately. A high-quality blade will reflect the marks of the grinding tool in the light. If the blade is rough and looks roughly processed, such a circular saw blade does not realize the efficiency of work, and it will become dull faster.
Any saw has its own dimensions, if the equipment for it must be selected taking into account this parameter. The diameter of the discs is important because different diameters will lead to losses. So, the cutting depth depends on the outer diameter. Experts say that the cutting depth above the workpiece must become small: this way the cut will be better, the heating will decrease, and the load on the engine will be small. It is essential that the disc is tightly fixed on the landing pin.
My saw blades. Part one
Among the most favorite tools in the homemaker’s arsenal. a circular saw. A disc for metal should be selected for it taking into account the number of teeth, on which the speed and cleanliness of cutting depend. If there are a lot of teeth, then the cut will be fine, however, the load on the engine will increase, and the chips will be more difficult to carry out. With a small number of teeth, the cut is rough and preliminary, but the chips are simply removed, and the cut is made faster. A huge number of teeth is 80-90, a small number. 10-40.
Just like any other tool, the saw needs timely maintenance. The most crucial moment is the sharpening of circular saw blades. Experts note that the carbide tooth wears out along the main top, not counting if powerful workpieces are sawn, then the side edges also wear out rapidly. Excessive bluntness of the saw should not be allowed, because it will be the least productive, in addition, it is not a fact that the discs can be sharpened.
Correct sharpening means ensuring that the cutting edge is sharp at the same time. If you sharpen them along one frontal plane, then the number of sharpenings will be less. Many owners of similar tools are interested in how to sharpen a circular saw blade. As you know, it depends on the material of the teeth. Sharpening in most cases is carried out on a wheel made of elbor on another greenish carbide, in other words, on the basis of diamond wheels. Elborov wheels are purposefully used when sharpening HSS saws, and diamond wheels. for cutters made of hard alloys. So that the sharpening is fast, but has less effect on the degree of wear, it is worth choosing diamond wheels with a larger grain size.
For sharpening, machines are also used that have different functionality. The most complex and expensive model methods provide automatic sharpening. When sharpening, the teeth should be set apart: if this is not made correctly, then at the time of the cut there will be a burning smell, side noise, and the material itself will move with jerks, which is not very comfortable.
Disc for circular on wood which one to choose
The circular saw is a versatile tool that works with controversial materials. from wood to plastic to sandwich panels. However, a well-chosen circular saw blade is required to keep the cut smooth and free from nicks. Note that there is no universal disc suitable for materials, because each product solves its own problems. Already today, do not save by buying products of an unknown brand. it is dangerous at first.
What remains to be done for our client saw blades are divided into two types:
- Solid ones are made of solid metal and feature sharply sharpened teeth. They are popular due to their affordable cost, ability to recover, in other words, re-sharpening. On the other hand, solid products wear out faster.
- Tungsten carbide blades for hand-held circular saws are more reliable and durable, because on the teeth they are equipped with cobalt sharpened solders, in other words, tungsten carbide. With the use of carbide materials, the products are more durable and reliable, however, if the discs become dull, it will be difficult to return them.
When choosing a saw blade, you should look at the design features of the products, the placement of the teeth, their shape:
- straight, uniform teeth suitable for cutting chipboard, wood, plywood or aluminum;
- variable alternating teeth are controlled with cutting wood of soft and hard texture, in other words, plywood, in addition to cross cutting;
- circular saw blade with trapezoidal teeth is used when working with chipboard, soft non-ferrous metals, plastic. Due to the special shape of the teeth, the material does not split, and the sawing itself is carried out in two steps. first, a preliminary cut is made, then the edges are trimmed;
- the teeth have a positive negative slope in another way: the first one is needed when cutting workpieces with thick walls, the second. with thin walls;
- the rarest teeth with deep depressions in them provide a good longitudinal cut of the tree species, at the same time sawdust is simply removed;
- small, closely spaced teeth allow cross-cutting of materials. The most comfortable among these types is a circular saw blade, for those who are busy with a tooth has a special protrusion at the back. By this design, the cut is made rapidly and moderately.
Before choosing one or the other disc, you need to solve yourself a few questions.
Who the saw blade is selected for a certain type of circular saw. If choosing for yourself it is worth taking into account both the power of its motor, and the speed of rotation of the spindle, and the diameter of the landing pin. A circular saw blade with a huge number of revolutions and teeth at a negative tilt angle will put a huge load on the engine. If you should definitely find out what the capabilities of your saw are. It is worth keeping in mind that any saw has a landing diameter, and therefore the disc must correspond to its dimensions. The choice of a saw blade implies attention to such information as the series of the saw blade, its design and outer size, the diameter of the bore.
Which company to choose a saw blade?
Completely, the condition of the disks should be monitored at all times, because their wear will affect the overestimated load on the mechanisms and at some point will lead to its complete wear. Thanks to constant sharpening, of course, to extend the life of the equipment, to improve productivity and reduce the time for the cutting process. If after sharpening the cut remains sloppy and the material moves unevenly, it means that more attention should be paid to the location of the teeth.
Which way to choose saw blades? It’s easy to do if you follow a few rules:
- Find out on the label the diameter of the bore and the outer diameter of the blade. you need to match the requirements of your saw features.
- Pay attention to the thickness of the disc: the thin ones provide a good and clean cut and are used when working with valuable species of wood, and the thick ones are purposefully used for preliminary cutting of materials.
- On the disc, it is indicated what the maximum permissible number of revolutions is. A low speed will allow you to develop a higher cutting speed, alas, it will lead to deformation of the blade and a poor saw.
- Evaluate the quality of the saw blade: if it is not bad, then the cutting plane will be smooth, without roughness and imperfections.
B. look for safety and choose saw blades that are designed for a particular type of saw. In addition, think about where to sharpen the circular saw blade, if your staff cannot do this.
Carbide saw wheel
High speed steel is strong enough, but not enough for some jobs. Then carbide materials with TC marking are used. The disc is half chrome vanadium steel, and the teeth are tungsten carbide, which are soldered onto it.
Circular saw blade for steel
Such wheels are widely used when working with metals and alloys. To avoid overheating, water cooling is used. If it is not provided, the discs are equipped with holes for less surface heating.
The material for the discs is high speed steel, sometimes chrome vanadium steel. This steel is alloyed with molybdenum, tungsten, vanadium, chromium, which significantly increases the strength characteristics. Marking. CV or HSS.
How to choose a saw blade for wood
For wood, high carbon steel with few teeth is a good choice. Pay particular attention to the thickness of the solder. It should be moderate, ranging from 1.6 to 2 mm. This thickness provides a good cut without unnecessary stress on the circular saw motor. It is important which type of wood we will cut: hard wood, soft wood with a coating, laminate or other wood products.
Diamond circular saw
For cutting stone, concrete and other durable materials, diamond-brazed discs are used, which are attached by laser welding. One of the strongest disc types to handle high density materials.
How to choose blades for a circular saw
There are many tasks that a circular saw can handle. Unfortunately, for all Spectra jobs, one saw blade is not enough. 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 dimensions, ending with the number of teeth and material. An illiterate choice can lead to tool breakage, and sometimes to an accident.
When choosing, pay attention to the technical characteristics of the circular, and already starting from this, you need to select a suitable circle. Some of these increase the load on the engine and may not be suitable for your tool.
Much depends on the type of your circular saw. everything is indicated in the instructions. But there is also a dependence on the type of work. which material will be processed.
- External diameter. Adapted to the size of the protective cover.
- Inner diameter. Depends on the size of the circular force shaft.
- Number of teeth. A large number of teeth has a negative effect on cutting speed and engine load, but the quality and cleanliness of the cut increase.
- Tooth tilt. Most often, the wheels have a positive angle of inclination of the teeth, which is well suited for ripping.
- The thickness of the circle and soldering. Determines how thick the cut will be. Greater width increases strength but increases engine load.
Circular saw for stone
The most commonly used saw is the diamond segment saw 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.
With 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?
Choosing the right disc is the key to a job well done, equipment safety and health safety. Because, for example, a circular saw blade for wood is not suitable for cross-cutting. When buying a tool, you need to pay attention to:
- Number of teeth. By this parameter, you can easily determine the purpose of the disc: longitudinal, end or universal.
- Tooth sharpening shape. Flat sharpening, alternating slope and trapezoidal shapes are common.
- Sharpening angle. For circulars, it is positive, for end circulars, it is negative.
- Saw blade diameters. The inner one must match the equipment seating shaft. External. to the dimensions of the machine or hand tool.
- Disc blade thickness. The thicker, the greater the cutting force and the increased load on the engine. Its power may not be enough for cutting.
Saw blade for wood. features of monolithic, carbide and universal devices, how to choose the right one?
On the market, a saw blade is presented in a wide range and when buying it is important to understand which option you should choose for work. If you make a purchase without thinking, this will significantly increase the risk of injury and degrade the quality of work.
Universal saw blade for wood
The first in the list of this type of tool are saw blades for wood for circular saws for ripping with up to 40 teeth, followed by universal blades (from 40 to 60). They close the saws for side sawing, where there are more than 60 teeth. The tooth shape of universal saws is a cross between longitudinal and transverse counterparts, the incisors are inclined by 15 °, and the teeth themselves are of an average size. The optimal number is determined at 46-48 incisors. Slots and holes for cooling are made along the diameter of the disc (this is especially important when ripping, where the speed is higher).
Solid saw blade for wood
This name is due to the fact that this saw blade for wood is made from a single piece of steel, has a large number of teeth and is made from high speed or chrome vanadium steels. The disc is marked with the abbreviation CV or HSS. Advantages:
- the possibility of re-sharpening;
- preference for soft breeds;
- obligatory tooth setting;
- speed of bluntness of the cutting edge.
The sharpening operation is carried out on special machines that have diamond emery wheels installed at a certain angle of inclination. It depends on the type of wood being cut. In some cases, it is possible to sharpen circular saw blades for wood by hand with a diamond-coated triangular file.
Types of saw blades for wood
Depending on the design, circular saw blades for wood are divided into categories: monolithic (made of a single piece of metal) and carbide (having carbide inserts on the teeth). For the intended purpose, there are devices for sawing ends and for longitudinal cutting. By the shape of the cutter, discs are:
- With a flat cutter. For rip sawing all types of wood.
- With replaceable cutter. The teeth have a variable inclination to one side and the other. A disc is used to cut wood up and down.
- With a trapezoidal flat cutter. Half of the teeth have a trapezoid shape. Such a saw cuts not only wood, but also polymers and non-ferrous metals.
- With a combined set of cutters. Four replacements alternate with one flat tooth. If you need a saw blade for wood for a clean cut, then it has the following configuration.
- With a curved triangular incisor. Applied over laminate.
- With feed stops (projections behind the cutter). Reduces saw speed and protects against hard wood knots.
- small (depth from 4 to 4.6 cm);
- medium (5-5.5);
- large (6.5-7);
- saw pro (6.5-14).
Carbide Saw Blade for Wood
This type has carbide tipped inserts. Note that the steel grade is not very important for sawing. Cobalt and tungsten carbide inserts are soldered onto a disc made of this material. With this design, the cutting speed is increased. The teeth can only be sharpened on machine tools. The saw blade for wood for an angle grinder with carbide tipped cutters is very popular as it gives a clean cut.
- keep sharpness well;
- have high quality workmanship.
- high cost;
- impossibility of sharpening to initial sharpness.
