Disk saw how to choose a disk. Table of comparative characteristics of circular saws

Equipment for circular, end and saber saw

The saw disk is an integral element of any electric saw. It is installed both on manual cutting tools and on stationary equipment. There are many types of disks that differ in the shape of cutting teeth, the corner of their sharpening, the diameter and material from which they are made. The productivity of the tool, the quality of the cut, as well as the safety of the operator depends on the correct selection of equipment to a certain type of material.

You should know that by changing the type of disk on the electric engine, you can process the following materials:

  • Wood of soft and hardwood;
  • Materials based on wood (FEP, MDF, chipboard, OSB, plywood, floor laminate, etc.D.);
  • Natural and artificial stone;
  • Non.Ferrous metals;
  • Plastic products;
  • Metal products (corrugated board, pipes, metal profile, reinforcement, etc.D.).

Each cutting tool is characterized by certain characteristics that should be taken into account before using.

Outside diameter

The diameter of the installed cutting tool cannot be larger than the internal diameter of the protective casing. In different models of aggregates, casings can have both small and large sizes. A large diameter disk cannot be installed under a casing with a smaller inner diameter. At the same time, you can install a small disk under a large casing, but significantly The safety of the use of the unit will decrease.

Diameters of discs for manual circular saw can be in the range of 130-250 mm.

Landing diameter

It is very important that the diameter of the unit shaft and the seat of the disk correspond to each other. Some types of sawing for sawing have Additional holes for hard fixation On the pin. The equipment, as a rule, has the seats of the following sizes: 16, 20, 22, 30 and 32 mm.

The number of teeth

This parameter affects The purity of material processing and performance. The smaller the teeth has equipment, the faster the workpiece is sawn due. But a decrease in the number of incisors leads to a decrease in the quality of the cut. An increase in the number of teeth, respectively, improves the quality of the cut. But it is worth knowing that the more teeth have the equipment, the greater the load is experienced by the electric motor of the device. Conditionally, the equipment for disk electric saws is divided into 3 groups:

For each specific task, equipment is selected with the required number of cutting elements:

  • The maximum number of teeth is required for sawing wood across the fibers;
  • For sawing along wood fibers, it is better to use a tool with a small number of incisors (up to 60).

Tilt of teeth

Equipment for manual or stationary circulars has a difference in the angle of inclination of the teeth. It is both negative and positive in relation to the radius of the disk.

Sloping angles of incisors may have the following values;

  • Angles from 5 to 15 ° are considered standard;
  • Angles from 15 to 20 ° are called aggressive (positive);
  • Angles from 0 ° to.5 ° are called conventional (negative).

For a end saw It is customary to use discs with zero or negative inclination of incisors. This is due to the fact that the working part of the equipment is included in the workpiece along a different path than the circular saw installed on a manual tool or on the machine. Disk with zero or negative inclination of the incisors, as it were, presses on the workpiece from above and bakes the material. At the same time, the workpiece remains motionless, resting against the limiter, which does not allow the disk to push it away.

If you install a similar disk on the circular, then it will be quite difficult to make a longitudinal cut. The saw will begin to push the workpiece, the cutting elements will be clogged with sawdust, and there will be an overload of the engine of the unit.

For disk electric saw it is more reasonable to use the equipment with a positive angle of inclination of teeth. In this case, incisors in this case, being to the surface of the workpiece at a certain angle, will crash into it like a rubbish, tightening the processed part for itself.

Reggers configuration

You can find out about the appointment of a particular disk based on the configuration of the incisors.

  • Directly sharpened teeth allow you to cut wood quickly, but at the same time dirty.
  • Toughs with alternate bevel in different directions allow you to saw wood in different directions, but do not take shock loads.
  • The combination of trapezoidal and flat teeth allows Avoid the formation of chips On the upper layers of the material, for example, when cutting wood and combustion plates and plastic.
  • The combination of teeth with three types of sharpening increases the speed of sawing and provides good The purity of the edges when sawing both soft and solid materials.
  • The alternation of triangular teeth and teeth with a concave cutting edge allows you to cut a laminate without using preliminary notch.
  • Teeth having worn chamfers and wide backs can withstand Cement and nails hit On the cut line.

Cutting Metal disk For a circular saw has a slightly different teeth configuration.

Circular saw disks parameters

Disk is a metal circle with teeth at the end. Saw wood saws for circular saws are designed for different tasks, what needs to be considered when buying. Incorrectly chosen equipment will lead to uneven cut, it will go tight with the expected corporal damage.

When cutting, it is necessary to monitor overheating. The steel is characterized by an increase in body temperature with constant friction, especially about wood. In this process, the metal expansion occurs, which leads to a skew “eight”. The deformation begins to manifest itself in a small beat, which has not previously been tested. Often, an increase in temperature causes small bulges on the body of the metal, which are not noticeable to the eye, but noticeable to the touch. Over time, they begin to expand and become even more noticeable. The operation of the circular with such a disk will lead to engine wear and breakdown in anchor.

When buying, you need to take into account the likely expansion, since even the disk corresponding to the characteristics of the tool may begin to expand from temperatures. There are thermal compensators to eliminate this defect. These are slots that take over the expansion and prevent it from deforming. In addition, by safety precautions, it is necessary to take periodic breaks to ensure the cooling of the engine and the circle.

Reza cleanliness indicator. Number of teeth. In models for productive operation of the teeth is smaller, and their size is larger. They also have a positive inclination. They cope much faster with a cut of wood plate or wood, but the edges are covered with garbage and unraveled fibers. They will have to be cleaned on their own using a chisel.

Disk on wood for pure cut has a larger number of teeth (from 42) with a negative slope. Their productivity is reduced, but they give a clean end in replacement, without protruding fibers.

It is important to look at the purpose of the disk. On the circular there is equipment for:

Characteristics and selection criteria

Saw discs can have many characteristics, but we are only interested in those that affect the quality and performance of the work. Therefore, we will only consider the main ones with short explanations of what their importance is and why they need to look at them. In total, five parameters of saw discs can be distinguished and not all of them are obvious. But let’s get down to business.

The diameter of the saw disk

Diameter is external and internal. The external is measured not along the edge of the disk, but at the end of the teeth. Here you can see a wide variety from several to tens of centimeters. The external diameter does not directly affect the quality of work, but affects the maximum cut of the cut. In addition, the larger the external diameter, the thicker the disk and, accordingly, will be thicker and drank. The external diameter will also be limited by the parameters of your tool, in particular the size of the casing. It must be indicated in the parameters of the power tool.

It is also worth knowing that the larger the diameter of the disk, the lower the maximum possible frequency of its rotation. So, for a saw disk with an external diameter, it can be 18-20 thousand revolutions per minute, and for a thirty-centimeter disk this is no more than 6-7 thousand. The choice here should be made based on the parameters of your power tool and tasks. Due to the features that we wrote above, buying disks with a diameter much more than required, do not need.

The internal diameter is also called landing. Everything is simple here. This is a hole in the center of the disk. It also can be of different diameters, but here you need to know one thing: the inner diameter of the disk should be suitable for the diameter of the spindle of your tool on which you install the disk. However, the mount is a separate conversation, sometimes a key is used for a more reliable mount and such discs should have additional grooves. That is, here you need to look only at compatibility.

Sawdust

We wrote above that there is dependence on the diameter of the disk. The larger it is, the thicker the canvas. But in many cases there are options when the diameter is the same, but the discs with different thicknesses. When choosing, you need to consider that the larger the thickness of the disk, the greater its resource. Such discs last much longer. This is explained by the fact that thin discs heat up faster and stronger, and this leads to accelerated metal deformation.

It may seem that the discs with a thick canvas is better, but they have two significant disadvantages. Firstly, the drink itself will be more and more material will be in wasted. It seems that this is a trifle, but if you need to cut a lot, then there will be a lot of material in the sawdust. Secondly, the speed of work will decrease. What’s better? It is worth watching on the basis of your task, but if you have to work a lot, then they often choose discs with a thick canvas. Even more slowly, but their resource is much higher.

The number of teeth

By the number of teeth, saw discs can be divided into three large categories:

And in this case, it is also impossible to say unequivocally which option will be better, since there are your nuances. If we talk about the quality of the saw, the more teeth, the higher it will. However, with an increase in the number of teeth, the speed of work drops. It is also worth noting that if the saw disk is carbide, then it can have the so.Called intermediate teeth, which are less than the main. They are not designed for a saw, but for ejecting chips.

What to choose? Again, the solution here is yours, but in practice, most choose wheels with an average number of teeth that will be universal. Of course, there are cases when disks with a large number of teeth are needed, mainly when a very even and clean cut is required or you have to work with certain materials. But if you doubt the choice, it is better to take a disk with an average number of teeth, it may not be the best choice of all possible, but reliable.

Tilt of teeth

The angle of the teeth is inclined by the angle of deviation of the cutting edge. There are three options in total, each has both their pros and cons of.

Zero angle of inclination. Such discs are usually used when working with metal.

Positive. The cut will be faster, but less careful.

Negative. The quality of the cut above, but the speed is below.

As you can see, the differences are quite significant, but in this case you need to choose based on the tasks. If you saw a lot, then this is a positive angle of inclination, since it will give a tangible increase in speed.

The shape of the teeth

The saw discs can also have teeth of different shapes, which significantly affects their properties. In monolithic discs, these can be wide and bent teeth, or small, similar to those that have a conventional hacksaw. The former are best suited for soft varieties of wood, the latter are more universal. The carbide disks have more options, here are the main ones:

Flat. Best suited for longitudinal sawing.

Alternate. There are both flat and beveled, have a negative angle of inclination. Good when working with plywood and other similar materials, as well as with a longitudinal cut.

Trepezoid. They are most often used in machines where there is a feed of wood. Guarantee high speed.

These are the main characteristics of saw discs, which are worth paying attention to. As you can see, they have quite a lot of features, so choosing a universal option that is simply impossible for all occasions. Especially if we are also talking about maximum performance. And we don’t even talk about wheels for wood and metal, in this case, for each material, you definitely need to buy individual products.

Well, if the task of maximum performance is worth, it is obvious that it will not work to save here anymore. Will have to buy different saw discs for different tasks. In addition, you need to buy from reliable manufacturers who produce quality products. By the way, about the quality. The difference between cheap discs and expensive ones is that the latter will last much longer (with proper handling), so it is far from the fact that it will be more profitable. Well, about fakes from alloys of poor quality and there is no need to talk.

Do we need high speed?

The engine power and the speed of the disk determine the performance of the saw. The quality of the performed cut depends on the frequency of rotation. True, it should be borne in mind that For various materials, the optimal cutting speed will also be different. So, it is better to process polymers with a low melting point at low speed of rotation (so as not to melt the edges), and solid rocks of wood and MDF. On a high.

Solid rocks of wood and MDF are cut at high speed

It is for targeted tuning to the desired material that is used Rotation frequency adjustment. In other cases, this option remains unclaimed. Therefore, discs often have only one idle speed. About 5000 rpm. So that Council for summer residents, not striving for the heights of sawing creativity: acquire A single.Speed saw.

How to choose a disc saw

Circular Saw, or as it is called by the people. The circular, appeared at the beginning of the last century and today is a high.Tech, convenient and productive power tool designed for wood and derivatives of materials (chipboard, fiberboard, plywood, etc. D.). The irreplaceability and advantages of the circular is that the tool holds the line perfectly, performs a transverse cut without problems and can work with a huge number of materials. In order to produce a cut of laminate, plexiglass, plastic or slate, just install the corresponding cutting disk and select the necessary operating mode (adjust the speed).

The disc saw does not work with materials from mineral compositions, for example, brick or concrete. But even here there are exceptions, for example, Makita has a circular saw with water supply and diamond disk in the kit. It should be reservated that for cutting and cutting metal, installation saws for metal are used, in fact it is a variation of a disc saw, but all the same, such a tool is taken into a separate category. In fact, the only restriction for a disc saw is the inability to cut along a curve, that is, only a straight line of the cut.

As a separate class of circular saws, Submissive disk saws. This tool is designed for inserting to a part anywhere, and not just from the edge. The submersible disc saw is distinguished by the complete absence of the lower automatic casing, and the cutting disk is located above the supporting plate and is lowered only when the tool begins to work. It is quite natural that such saws have the ability to adjust the depth of the cut, often from the range of this indicator differs millimeters. The submersible disc saw found its application during roof repair, while dismantling the floor boards, the manufacture of grooves and cracks.

Today, manufacturers offer disk saws not only With power supply, but also units Working on batteries. Modern technologies made it possible to achieve that such a high.Power tool as a disc saw is equipped with a rather capacious battery and an economical engine. In addition, chargers for such batteries are particularly charging, so the forced rejection for refueling can be only 30 minutes. Of course, the battery disc is an incredibly ergonomic and mobile instrument that, for example, roofers, will appreciate, for example.

Determining the main working parameters and characteristics for the selection of a circular saw, perhaps the most important and the main one is Diameter of cutting saw. It is logical that the larger the cutting disk, the more powerful engine the tool should be, the higher the torque indicator should be and the more efficient the electrostabilization system should work. Naturally, the higher all these values, the greater the dimensions and weight of the tool, as well as the cost of the unit.

The maximum depth drank also one of the main options for choosing. Depending on this indicator, disc saws can be divided into three groups. The first with the maximum depth was sprinkled in the range from 40 mm to 50 mm. The tool is suitable for cutting sheet materials and work in the place. The second group of the tool with maximum depth of drank 50-65 mm is the most common universal disk saws. Professional models, let’s say, a swings tool in its class-these are circular with the most depth of drank from 65 mm to 140 mm.

Of course, in the case of the emergency need for the cut of a very volumetric element or parts with a high height, you can contrive and make a cut on both sides, that is, the cutting disk will not pass through the workpiece.

From rotation speed of cutting disk The cleanliness of the cut depends, although there is one nuance here, because the selection of the cutting disk, that is, the quantity and shape of the teeth, directly affects the purity of the cut. It should also be borne in mind that the speed of rotation is highly generated, which will be undesirable during work with some materials, for example, certain types of plastic. It is optimal to choose a disk saw with the ability to adjust the idle frequency.

If you are not very limited by financial capabilities, then we recommend that you buy a disk saw with additional options and functions. The presence of such Smart electronics will never be superfluous, because it increases not only the performance and efficiency of work, but also guarantees maximum comfort and safety for the operator, plus. Will help to avoid a premature failure and significantly extends its service life.

  • The function of constant speed or constant electronics, will help prevent the disk jacket and contributes to the purity of the cut.
  • The ability to adjust the speed idle passage will allow you to choose the corresponding mode of operation for various materials.
  • The function of smooth start It will prevent the leap of the tool at the very beginning of the work, which will protect the saw engine from excessive loads, thereby prolonging the service life of the circular saw.
  • Availability overload protection systems to automatically turn off the tool, when it is at the limit of power. Again, the tool will allow the tool to serve a longer period of time.
  • Engine brake The operator will protect the operator from injuries, the tool from the reverse blow, and the part or structure of the structure from damage or breakdown.

Before buying a circular, look at support plate tool, because the functionality of the saw also depends on this element. It is on the supporting plate that all the necessary mounts and mechanical adjustments are installed for additional elements. It is best to choose a saw with a support platform from light alloys of metals, and it should be made by casting.

A circular saw. Types and device. How to choose and features

Circular saw, or a disk saw. A tool for cutting various materials by sawing a disk with teeth. It is mainly used to perform carpentry and carpentry work.

Manual Devices consist of a case with two handles in which an electric motor is located. A gear disk is fixed on the engine shaft of the engine. Part of the disk protruding from the case is closed by a casing. During sawing, the protective casing is pushed by the workpiece. Upon completion of sawing, the casing is returned back by the spring.

Stationary The saw has a table instead of a compact case. The engine is fixed under it so that part of the saw disk goes through the slot in the countertop. At the same time, the disk itself can be located both on the shaft of the motor, so be associated with it through the belt gear.

Differences between manual and stationary saws in terms of convenience and functionality

Portable manual and desktop stationary disc saws differ among themselves in terms of convenience of use when performing various types of work. For some tasks, one tool is preferable, and for others another. Therefore, no variety has a clear advantage over another.

Features of a desktop circular

Stationary circular saw is equipment for the workshop. It is applicable when performing a large volume of the same type of work. The presence of a table, as well as the use of various auxiliary devices with it, allows you to achieve high accuracy when cutting.

  • Cutting small plates of sheet materials.
  • Cut the boards, rails, timber.
  • Sample of a quarter.
  • Patch.
  • Remove the chamfer.
  • Saw wood.

To make such an extensive volume of work on the circular table, it is required to use in addition to a parallel emphasis on a number of other devices. At the same time, the functionality of the table largely depends on the size of its countertop. If the material is not placed on it, then many types of work become excessively complex or almost impossible. In addition, since for cutting the workpiece should be raised to the table, two operators have to perform work with large.Sized lumber.

Table circular saw can be used to harvest firewood. With its help, thin wood trunks and branches into short blocks are sawed. For these purposes, the cheapest tool is usually bought, which does not support the function of adjusting the disc leave, changing its angle.

Features of a manual circular

Hand disk saw is a mobile tool. It is light, therefore it is used on construction sites, where there is a need to produce accurate sawing.

Mobile circular saw takes up little space, it costs cheaper. Due to the presence of parallel stops with its help, you can dissolve long lumber along. In this case, it is possible to obtain a mowing cut. In general, such a tool can work with much larger format blanks than it is possible to process on a circular table. The mobile saw can be raised to the roof to file rafters or beams in place.

Using the setting of depth of the cut, you can make a sample of a quarter or long groove. However, the implementation of such work is limited by the capabilities of the lateral emphasis. Despite many restrictions in terms of accuracy and functionality, disk mobile saws are the best. The possibility of modernization speaks in their favor. In particular, they can be installed on a homemade table, thereby turning into a full.Fledged stationary machine. Having finalized the circular in this way, it can be used for a more accurate cut, manufacturing the spike-puzzle connection, remove the chamfer on the workpieces.

Technical parameters of circulars

Various devices of saws, even with a similar constructive structure, still differ among themselves in a number of technical features. Each parameter is important, since it directly affects the possibility of performing certain tasks.

  • Disk diameter.
  • Power.
  • Adjusting the depth of the disc and tilt of the disk.
  • The presence of a smooth start.
  • The number of revolutions.

The disk is directly involved in the cut part of the saw. It depends on its diameter how thick the part can be cut with a specific tool. This is extremely important if it is planned to use it for the cut of thick timber, for example, beams or wooden pillars for fences. The depth of the drunk of the grinder is slightly less than half of the diameter of the disk.

Table circular saws can have a disc diameter of 400-500 mm or more. Such equipment is specialized and used for cutting thick lumber, as well as cuts on the boards. The most popular desktop models are rarely equipped with discs of more than 210 mm.

As for the manual circulars, the diameter of their saw disc is mainly up to 210 mm. At the same time, such a tool is equipped with a heavy powerful engine, which makes it carrying and using it complex. For example, a saw with a disc 335 mm on average has a mass of 13 kg. At the same time, a tool with a saw of 165 mm weighs 3.5 kg. Most often, a mobile circular saw is equipped with a dial with a diameter of 160-190 mm, which gives the necessary level of maneuverability when carrying and working. The tool with such parameters saws deep enough, while it is quite lifting.

Power is one of the defining criteria when choosing a tool. However, when using a new sharpened saw disk, even with a low.Power motor, it will be able to saw better than a powerful tool with worn equipment. Thus, the lack of power of torque can be compensated by consumables. It is necessary to decide in advance. Overpay for a powerful circular once, or then sharpen the discs more often.

A circular saw with a motor up to 800 watts can be used to work with plywood, thin slats and boards. Tool with engines 800-1200 W is the most universal. He easily cuts almost any lumber, but when sawing thick blanks, he does it slowly. When choosing a desktop circular, it is better to stop on a motor from 2 kW. In this case, it will have a power supply for any type of work. At the same time, its weight does not matter, since the table is always in the workshop.

Appointment and device

A manual circular or disk saw belongs to household appliances, which cuts wood horizontally straightforwardly, plastic and other “soft” materials (including metals of low thickness) at different angles. The basic elements of the design of the device, regardless of the brand and model:

  • Power unit;
  • Engine (with or without gearbox), rotating the leading shaft;
  • Metal disk-saw with acute gear borders;
  • Dense plastic or rubberized casing.

In the design of the model, one or two handles of various shapes, lock elements, fixing or guide supports and pulleys, power cord, battery and others (laser pointer, ruler, etc. May be present.P.).

Best Battery Disco

Battery saws are great from network “relatives”. Firstly, this type of disk drank the highest mobility indicators. Secondly, in battery saws, power, like revolutions, is less compared to network analogues. Thirdly, the weight of the battery saw above.

As a result, the following comes out: this type of saw is better suited for the saw of the tree with soft and medium hardness, as well as thin sheet metal.

Below Consider the three best models of battery saws.

This model of a disc saw is an example of individuality in combination with good quality and quite adequate price. The engine resource of this tool is quite high, which will allow you to use this equipment for a long time.

The main problem of this model is an unpopular standard, which is why it is difficult to find suitable components for this model.

The landing diameter of the disk is 16 mm, which can be considered not too popular the size, which means that problems with the discs are likely to be. If it turns out to find a relatively suitable disk, you will have to put a extension puck.

What is amazing. Cut lines and risks on the case that do not coincide, the backlash of the spindle, the loud sound of the engine start.Up.

Bosch GKS 10.8 V-Li 0

This model, produced by Bosch, is considered one of the successful battery saws

She attracts attention with a number of features. For example, the speed of rotation is only 1400 rpm

This speed is enough for the cut of a not too hard tree.

Further, what should be noted. This model has good dimensions, which means that it will be very convenient to work with this saw.

Judging by the reviews of users, many people like the dimensions and productivity of the tool, although the quality in separate moments could be higher.

The tool, according to consumers, turned out to be easy enough, and therefore it is easy for them to operate. The presence of indicators will allow timely to learn about the status of the charge.

This model came out expensive, but its purchase justifies itself at 100%.

  • Compatibility with the entire line of tools from Bosch;
  • Small dimensions;
  • Small weight. You can use one hand;
  • Good equipment;
  • You can connect a vacuum cleaner;
  • The presence of a highlight and indicators as a notification.
  • High price;
  • Expensive maintenance and repair;
  • Weak battery;
  • The disk can “depart” from its place, which reduces the accuracy of the saw.

AEG BKS 18

A powerful and inexpensive model of the German company AEG, which is part of the Electrolux concern, can be a good addition to any carpenter. High quality is due to numerous checks in the production process and compliance with world standards.

This model has very good acceleration. It reaches 2500 rpm. This is enough for the cut of boards with a thickness of 50 mm. The engine is also not bad, since such a speed of rotation.

The only “but” of this battery saw. The device is very hot in the heat. Finding wheels for such a model is not always easy.

  • Attractive price;
  • It cuts a tree well;
  • High engine power and equipment quality;
  • Performance at the right level.

This group of cutting tools has its characteristic features and parameters: dimensions, type of material and its properties, purpose, etc.P. Over, even the saws of one manufacturer, such as Aspi, differ from each other in a number of parameters. We highlight some of the main criteria that affect the final choice.

Type of saw disk

Despite the variety of models, samples of different manufacturers, all samples are divided into 2 large categories:

1) monolithic. They are made of continuous metal, high.Carbon, high.Speed steel is used. There are two varieties of configuration of cutting tools:

  • ¾ sharp straight teeth, similar to those used in hacksaws, with straight.Line cuts (in the longitudinal and transverse direction). Equally good when working with soft and solid wood;
  • ¾ curved shape in teeth having a characteristic wide back allows you to effectively and efficiently process soft wood.

2) Disk carrier saws. Such specimens deservedly are not only more reliable and effective, but also safe. For their production, instrumental steel of increased strength is used. Such discs to increase strength are enhanced by attack. The high content of cobalt and tungsten carbide allows for high physical and mechanical properties and operational parameters. Such samples are favorably different from analogues in a number of characteristic features:

The only thing you should pay attention to is the slightly higher cost of samples. But the funds invested in the purchase of carbide saws, for example, such as Polish Faba, pay off fast enough. Another relative drawback is the complexity of sharpening. To restore the initial characteristics, the use of special equipment will be required.

Dimensions in diameter

Another parameter affecting the choice is the diameters of the saw discs. When buying, you must pay attention to the following parameters:

  • Outside diameter. This parameter must be taken into account in accordance with the size of the casing of the saw machine. It is obvious that a large disk cannot be installed on a machine with smaller dimensions of a protective casing. Also, you should not install sawdrops of too small diameter.

In addition, the external diameter directly affects the maximum permissible depth of cut. The speed of wood processing in this case does not change in any way. If the task is to purchase a saw disk for manual cutting power tools, it is necessary to consider samples with an approximate diameter of 13.0 to 25.0 cm.

It is important to consider such a technical parameter as the load on the engine. Here the dependence is directly proportional: the deeper the dent of the disk is immersed in wood, the higher the load. Do not try to make accurate calculations, just pay attention to the height of the teeth protruding over the workpiece. Optimal. 10. 20 mm.

  • Inner diameter. An accurate, clearly fixed disk planting is, first of all, safety! It is impossible to neglect this parameter. In addition, if the diameter exactly corresponds to the size of the pin, the saw will work more accurately, clearly, without vibration and, accordingly, marriage!

Manufacturers of electrical engineering used for woodworking took care of the convenience of users, and installed unified parameters for pins of the machines. In total, several main typical landing sizes are distinguished: 20, 22, 30 (32) and 50 mm.

Please note: a number of sawing machines, to increase the reliability of fixation are equipped with additional recesses-veneers, where fixing pins are installed.

The number of teeth, shape and other important parameters

The number of teeth is the most important indicator to which you need to pay attention. In total, experts distinguish 3 main groups:

See also  Format saw for cutting laminated chipboard

This parameter is important and should be taken into account depending on the upcoming type of wood processing. If a transverse cut is carried out, the discs with the largest number of incisors should be installed. High speed and frequency allow you to avoid chips and saw any woody blanks without marriage. Wandering the blanks along the disks with a small number of teeth (optimally. 18).

The shape of the cut, first of all, is important to achieve the optimal quality of workpiece processing. According to experts, the optimal choice for effective processing is modifications, the design of which provides for variable sizes of teeth. Such details are ideally combined with any type of wood and are characterized by the best price and quality parameters.

The angle of inclination can be negative. So it turns out if the deviation towards the back is fixed, the positive. When deviated in the opposite direction of the canvas.

On the angle of inclination of teeth, discs are also divided into 3 groups:

Standard tilt between 5 to 15 °.

Positive inclination (demonstrates the aggressive style of woodworking), the angle of inclination 15. 20 °.

3.Negative angle (can reach.6 °).

Most manufacturers of consumables for sawing machines, such as Nook, offer their customers all the presented disk saws presented.

Feature of the universal saw disk

The correct selection of consumables for circular saw is considered a whole science. In this case, it is necessary to take into account certain parameters and correctly compare the characteristic features of each disk model.

Experts recommend choosing products after familiarization with the opinion of experts. The lack of experience can cause injury in production or provoke a breakdown of sawing equipment.

  • Do not save on consumables. Some experts prefer to use universal types of models that allow you to work with wood and metal structures.
  • However, when selecting such an element, it is important to take into account the presence of professional skills.
  • Experts say that the disc for the circular should be selected taking into account the task.

For example, models with a negative angle of teeth are used for end saws. Thanks to them, it is possible to get a uniform cut. Choosing such models for equipment of the sawing table is prohibited. The fact is that during the launch the wood blank is observed.

Disks products, in the device of which on the tooth are located at a negative angle, have an additional row from the interdental sinuses. Thus, the number of cutting surfaces will increase. In the process, the Rapid clogging of the metal parts is observed with sawdust. As a result, the speed of work and its result are violated.

Saw discs are divided by each other in their constructive features. These include:

  • Monolithic. Disk design is made of dense steel. The advantages of such products are the minimum cost and the ability to independently sharpen metal knives. In addition, the device can be repaired, thereby providing a good margin of safety;
  • Cool. Its base is made of dense steel, and cutting teeth made of hard alloy, to which a little tungsten carbide is added. As a result, it is possible to obtain increased hardness in the saw edge, a uniform cut and an enlarged interval between the lifting.

Cute attack disks models are designed to perform array at speed speeds. Thus, it is possible to increase the volume of performance.

The main drawback of such a design is the correct maintenance. It consists in the use of special tools and the presence of professional skill.

General information

As there is no panacea from all diseases, so there is no one universal saw element for all types of work with wood. For quick, high.Quality, and most importantly, safe work, each operation requires the appropriate disk.

Before choosing a disk, you need to decide on the working material:

  • The tree of the tree is solid or soft;
  • A cut will be carried out along or across;
  • The type of workpiece-boards, plywood, chipboard, the presence of any coating.

If the transverse cut is well carried out with a disk with a negative angle of teeth, then for the longitudinal this option is unacceptable due to the occurrence of the repulsion effect, so that the model for longitudinal sawing is not suitable for the transverse. Negative consequences can occur for a saw engine. Sawdust, clogging into the interdental sinuses, create huge overloads to the engine.

For each type of work, the corresponding discs are selected that may differ:

  • A series or a hint for you in a painful choice;
  • With the type and angle of the teeth. With a positive inclination, the cut is done faster, but inaccurately, with a negative on the contrary, slowly, but clean;
  • The number of teeth. A large amount of them (80–90) is suitable for pure cut, but the work slows down by accumulating chips; The smaller the teeth (10–40), the faster the work goes, the chips are taken out, but the cut looks torn;
  • Design. On a high.Quality disk, grinding traces diverge from the center, t. E. Each processed separately; The surface should not have roughness, otherwise it will heat up and teeth will blunt faster; The rings of stiffness, wave.Like extensions and a special coating of the canvas also indicate its good quality;
  • External diameter;
  • The diameter of the landing hole;
  • Maximum speed;
  • The thickness of the canvas. The thin disk creates the minimum load on the engine and can be used in a battery saw, but it is not adapted for hard work;
  • Marking. On high.Quality samples it is laser and contains information that is considered here by points.

Of course, you should know the technical capabilities of your tool, which include:

  • Engine power, which will “pull” high.Speed disks; a large number of teeth and their negative angle;
  • Spindle rotation speed. Proportion size of the canvas = drive power is better not to violate and not see the consequences;

Rotation speed depending on the diameter

  • The size of the planting pin, which guarantees a reliable landing of the disk, otherwise the collapse is bought, but it is advisable to choose the right size. For example, a saw on wood 200×32 should be installed on a pin with a diameter of 32 mm;
  • Permissible external diameter, the protective casing serves as an additional limiter.

What to pay attention to when choosing a saw wood disk?

The key features on which you should FOCUS on when choosing a saw disk for a grinder are as follows:

  • The outer diameter of the equipment.The size of the circle largely depends on the power of the USM and the type of work on the work. The most suitable for wood are 2.5 cm discs. Larger diameter increases the performance of work, but requires professionalism and increased measures to comply with safety precautions.
  • Internal (planting) diameter.For corner grinders it is standard. 22 mm. Otherwise, discs can be installed through special transition rings. Some equipment of equipment can be equipped with this accessory.
  • Disk type.Monolithic equipment is characterized by low cost, but requires periodic wiring and sharpening. Reliable carbide disks do not require frequent maintenance, they provide clean cut at any speed.
  • The number of teeth.The transverse cut requires the use of discs with a large number of incisors-60-90. Accordingly, the longitudinal cut is better when using models with a small number of teeth.
  • Rotational speed.High.Speed discs are suitable for working with a dense and solid tree. Supporting low.Speed equipment is ideal for soft and viscous wood.

A circular saw. Types and device. How to choose and features

Circular saw, or a disk saw. A tool for cutting various materials by sawing a disk with teeth. It is mainly used to perform carpentry and carpentry work.

Manual Devices consist of a case with two handles in which an electric motor is located. A gear disk is fixed on the engine shaft of the engine. Part of the disk protruding from the case is closed by a casing. During sawing, the protective casing is pushed by the workpiece. Upon completion of sawing, the casing is returned back by the spring.

Stationary The saw has a table instead of a compact case. The engine is fixed under it so that part of the saw disk goes through the slot in the countertop. At the same time, the disk itself can be located both on the shaft of the motor, so be associated with it through the belt gear.

Differences between manual and stationary saws in terms of convenience and functionality

Portable manual and desktop stationary disc saws differ among themselves in terms of convenience of use when performing various types of work. For some tasks, one tool is preferable, and for others another. Therefore, no variety has a clear advantage over another.

Features of a desktop circular

Stationary circular saw is equipment for the workshop. It is applicable when performing a large volume of the same type of work. The presence of a table, as well as the use of various auxiliary devices with it, allows you to achieve high accuracy when cutting.

  • Cutting small plates of sheet materials.
  • Cut the boards, rails, timber.
  • Sample of a quarter.
  • Patch.
  • Remove the chamfer.
  • Saw wood.

To make such an extensive volume of work on the circular table, it is required to use in addition to a parallel emphasis on a number of other devices. At the same time, the functionality of the table largely depends on the size of its countertop. If the material is not placed on it, then many types of work become excessively complex or almost impossible. In addition, since for cutting the workpiece should be raised to the table, two operators have to perform work with large.Sized lumber.

Table circular saw can be used to harvest firewood. With its help, thin wood trunks and branches into short blocks are sawed. For these purposes, the cheapest tool is usually bought, which does not support the function of adjusting the disc leave, changing its angle.

Features of a manual circular

Hand disk saw is a mobile tool. It is light, therefore it is used on construction sites, where there is a need to produce accurate sawing.

Mobile circular saw takes up little space, it costs cheaper. Due to the presence of parallel stops with its help, you can dissolve long lumber along. In this case, it is possible to obtain a mowing cut. In general, such a tool can work with much larger format blanks than it is possible to process on a circular table. The mobile saw can be raised to the roof to file rafters or beams in place.

disk, choose, table, characteristics, circular

Using the setting of depth of the cut, you can make a sample of a quarter or long groove. However, the implementation of such work is limited by the capabilities of the lateral emphasis. Despite many restrictions in terms of accuracy and functionality, disk mobile saws are the best. The possibility of modernization speaks in their favor. In particular, they can be installed on a homemade table, thereby turning into a full.Fledged stationary machine. Having finalized the circular in this way, it can be used for a more accurate cut, manufacturing the spike-puzzle connection, remove the chamfer on the workpieces.

Technical parameters of circulars

Various devices of saws, even with a similar constructive structure, still differ among themselves in a number of technical features. Each parameter is important, since it directly affects the possibility of performing certain tasks.

  • Disk diameter.
  • Power.
  • Adjusting the depth of the disc and tilt of the disk.
  • The presence of a smooth start.
  • The number of revolutions.

The disk is directly involved in the cut part of the saw. It depends on its diameter how thick the part can be cut with a specific tool. This is extremely important if it is planned to use it for the cut of thick timber, for example, beams or wooden pillars for fences. The depth of the drunk of the grinder is slightly less than half of the diameter of the disk.

Table circular saws can have a disc diameter of 400-500 mm or more. Such equipment is specialized and used for cutting thick lumber, as well as cuts on the boards. The most popular desktop models are rarely equipped with discs of more than 210 mm.

As for the manual circulars, the diameter of their saw disc is mainly up to 210 mm. At the same time, such a tool is equipped with a heavy powerful engine, which makes it carrying and using it complex. For example, a saw with a disc 335 mm on average has a mass of 13 kg. At the same time, a tool with a saw of 165 mm weighs 3.5 kg. Most often, a mobile circular saw is equipped with a dial with a diameter of 160-190 mm, which gives the necessary level of maneuverability when carrying and working. The tool with such parameters saws deep enough, while it is quite lifting.

Power is one of the defining criteria when choosing a tool. However, when using a new sharpened saw disk, even with a low.Power motor, it will be able to saw better than a powerful tool with worn equipment. Thus, the lack of power of torque can be compensated by consumables. It is necessary to decide in advance. Overpay for a powerful circular once, or then sharpen the discs more often.

A circular saw with a motor up to 800 watts can be used to work with plywood, thin slats and boards. Tool with engines 800-1200 W is the most universal. He easily cuts almost any lumber, but when sawing thick blanks, he does it slowly. When choosing a desktop circular, it is better to stop on a motor from 2 kW. In this case, it will have a power supply for any type of work. At the same time, its weight does not matter, since the table is always in the workshop.
