    Circular saw SPARKY TK 65

    Features of the

    Saw blades have a number of basic parameters to help you distinguish between them.


    • outer diameter;
    • inner diameter;
    • number of teeth;
    • tilt of the teeth;
    • the shape of the teeth;
    • product thickness.

    Outside diameter is generally not a significant indicator for cutting speed. He is responsible for the cutting depth. It can be determined by the inner diameter of the saw cover. A large circle (305-355 mm) is not placed on a product with a smaller casing diameter. (By the way, it is not recommended to remove the protection for safety.) Most often, products with an indicator from 130 to 250 mm are taken for such a saw.

    The inner diameter must have the same value with the dimensions of the power shaft on which this product is fixed. If it is larger, then when the saw is operating, the off-center disc creates large vibrations, which leads to severe wear of the bearings and the shaft itself, as well as breakage of the disc or its teeth. In addition, such a fastening is a gross violation of the work regulations, and is dangerous for humans.

    The cutting speed depends on the number of teeth on the disc in direct proportion. In addition, a large number of them gives a smoother and more accurate cut. But there is also a significant drawback of this approach. it is an increased load on the sawing tool engine. There are disks:

    • with a large number of teeth (from 80 to 90 pcs.);
    • with an average number of them (from 40 to 80 pcs.);
    • small-toothed (up to 40 pcs.).

    For high-quality sawing, the inclined angle of the teeth is also very important. It is fixed by the deviation of the cutting edge of the tooth from the radius of the saw blade. This parameter can be:

    • standard (the angle varies in the range of 5-15 degrees);
    • positive (tilt 15-20 degrees);
    • negative (0 to minus 5 degrees).

    Finally, the configuration of the prong. Each shape is designed for a specific cut. Therefore, a tooth is distinguished here:

    • flat. cuts longitudinally at high speed;
    • trapezoidal flat (alternation of high trapezoidal and low flat teeth). cuts wood, plastic and soft types of metals (aluminum);
    • replaceable (the teeth have an alternate slope to the right and left). helps to cut wood, chipboard and composites cleanly both along and across;
    • combined (one flat cutter follows four replaceable ones). completely universal;
    • interchangeable with a larger sloping side. used for choppy types of material, as well as for clean cuts at right angles.

    As for the thickness of the saw blade itself, the thickness of the cut depends on it. The standard is 3.2 mm. If the indicator is higher, then this will reduce the amount of material, and if much less, then this will lead to overloading of the equipment and possible deformation of the disk.

    However, when working with each type of material, there are also peculiarities of saw accessories.


    A miter saw is a tool designed to make straight cuts at a given angle. The saw cut angle can be either 90 degrees or 45. Its main advantage is that it copes well with long details and unusual shapes of surfaces. A striking example of these is a plastic floor plinth.

    But this tool has other features.

    The miter saw can cut a large number of equal (given size) miter and straight slots. That is why it is a must in the set of craftsmen for the manufacture and assembly of furniture and doors.

    The appearance of this unit resembles a conventional circular saw (circular) mounted on a movable arm. It allows the discs to descend not only vertically, but also at any angle of inclination. This tool can cut various materials:

    • wood;
    • metal (in particular aluminum);
    • plastic;
    • a rock.

    As with any saw, the type and quality of the blade depends on the material chosen. For the most effective work, you need to choose the right component.

    How to choose the right one?

    In modern renovation, most often required miter saw blades for aluminum, plastic and stone. These materials are actively used to create modern decor.

    In order to choose a blade for soft metals and polymers, you need to know that there is a difference in sawing a hollow structure or a dense solid. The quality of the cut here mainly depends on the number of teeth. So, to obtain a result close to ideal, with hollow structures, it is better to use discs with a large number of teeth. Dense material is better sawn with a small-toothed nozzle.

    An important criterion is the thickness of the disc and the material from which it is made. The best choice is a solid carbide (high carbon) metal cutting attachment. It lasts longer and can be re-sharpened. The same cannot be said for welded teeth.

    This quality is inherent mainly in European brands. The cost when choosing an expensive brand name pays off during operation.

    Good quality can be noted in the brands Bosch, DeWALT, Makita, CMT. The same firms also produce construction tools, including miter saws.

    If we talk about the angles of inclination, then for soft materials such as plastic, it should be negative. This gives the cleanest cut possible. The shape of the teeth is quite varied. The universal drive may be the best option. You can never go wrong with him.

    How to change a Miter Saw blade – Quick and easy! #DeWalt

    A simple alloy of metals is not enough to perform a high-quality cut in stone. A harder material is needed here, in the role of which is diamond sputtering. In this case, the decisive factor in the selection is the grain size of the abrasive coating. The larger it is, the less beautiful and high-quality the end cut will be. Fine diamond plating is much more useful and clean. But to prevent engine overheating, it is better to choose not the smallest value.

    It should be noted that the blades of such circles only vaguely resemble teeth. Their design is more like a periodically divided, monolithic cutting blade. The shape is explained by the fact that the sawing is carried out due to the friction of the abrasive against a hard stone.

    • Circle replacement

    A tool such as a miter saw is not familiar to everyone. Despite the large number of materials that this tool can cut, its main purpose is specific. Therefore, such a saw is often used by professional finishers. At home, it does not become necessary so often. However, when you do not want to overpay for repairs, it makes sense to purchase all the necessary tools to make your work easier.

    But in this case, you need not only to understand the principles of working with it, but also to understand the consumable parts of this tool. The main of these parts is the cutting disc.

    Circle replacement

    When performing repairs even at home, the periodic change of materials also requires the replacement of the saw blade. It is not difficult to change it, but it is still worth knowing the correct sequence of actions for your own safety.

    It is necessary to start by installing the protective plastic casing (if any) in the upper position. To do this, unscrew the side auxiliary bolt, raise the structure, and then fix it with the same bolt, just in a different position.

    Next, take a hexagon, which unscrews the clamping bolt in the center. In this case, on the back of the saw, it is necessary to press the button of the shaft locking mechanism, which is a stopper. It prevents the shaft from moving. Therefore, while holding it, you can press out the central bolt using the hexagon. Then the bolt must be unscrewed (you can use your hands), remove the side stopper (looks like a wide washer) and then the disc.

    Installation is carried out upside-down. The disc is put on the shaft, then a lock washer is placed, then the bolt is screwed in by hand until it stops. To clamp the nozzle, you must press the button, and, while holding it, tighten the central bolt to the limit using a hexagon.

    Once the saw blade has been mounted, it can be checked for strength with a slight longitudinal movement. If there is no backlash, the installation is correct, and you can start cutting.

    For information on how to sharpen a miter saw blade, see the video below.

    Cutting depth

    This parameter depends on the diameter of the disc. It reaches its maximum when cutting at 90 degrees, and decreases when cutting it. When choosing a miter saw, specify what diameter discs can be installed on it, and what depth of cut they will give. An additional benefit is the cutting depth stop. It allows you to carry out a high-quality selection of grooves.

    Outer and rim diameter of the disc

    The rim of the blade affects whether it can be fitted to the saw at all. The most popular value is 30 mm. As a rule, you will come across saws designed to work with just such a consumable.

    There is much more variety in the outer diameters of the discs. It can be specified in inches or millimeters. The most popular is 255 mm. The larger the diameter of the consumable, the larger the workpiece you can cut. To work with a large blade, the saw will need more power. In any case, you will not be able to install a disc with a diameter larger than the allowable one. it will not snap into place. This design feature of miter saws ensures safety during work.

    It is also not recommended to install discs of too small diameter. When you turn on the saw, the engine will experience a minimum of resistance and will start to produce too many revolutions. this will harm the saw.

    Speed ​​control

    This feature allows you to customize the saw for certain materials. Different types of wood, materials based on it, plastics, plexiglass, etc. require different values ​​of the number of revolutions of the disk.

    Choosing a miter saw

    It is impossible to imagine the sphere of woodworking without the use of a special tool. One of the popular tools is a miter saw. Already from the name it becomes clear that its main purpose is the processing of the ends of the blanks, that is, the transverse cut of wood. This differs from the circular saw, which is used for ripping.

    Changing the blade on a miter saw

    Understanding how to choose a miter saw is not very difficult, but only if you understand the basic concepts and characteristics. In any case, a consultant will help you, but the process will go faster if you know what questions to ask. Further in the article we will consider the device of miter saws, their technical characteristics, additional functions and consumables.

    Saw blades

    The saw blade is very important. Its parameters affect the depth and width of the cut, the required saw power. In addition, discs are different in the number of teeth, their size and shape.

    Asynchronous motor

    Among all types of motors, asynchronous is considered the most economical. It is reliable and makes little noise. Asynchronous motors are reliable, as they have a minimum number of rubbing elements. This allows them to heat up a little and not wear out for a long time. the only part that is subject to wear is the bearings.

    Among the disadvantages is the high weight-to-power ratio. An asynchronous motor with a power of about 2 kW will weigh about 20 kg. This imposes some restrictions on its use, since it is not very convenient to use an overly heavy instrument. In addition, when operating on electricity at industrial frequency, the engine will not be able to develop a rotor speed higher than 2850 rpm.

    Working at an angle and inclination

    The ability to adjust the swivel and tilt significantly expands the functionality of the saw. An angled cut is provided by a rotatable section mounted on the bed. With its help, you can turn the disc in relation to the workpiece. Tilt cuts are available on models in which the blade can be tilted to one or two sides. If you need to carry out such work, check the availability of these functions in the tool.

    Cutting depth limitation

    This feature aids in grooving or trimming jobs by limiting the depth to which the disc can plunge.

    How to choose a metal blade for a miter saw

    Types of rotation gears on the machine spindle

    Rotation is transmitted to the disc by means of a gearbox. But a belt drive can be used. Each method has its own pros and cons. Thus, the belt drive is very quiet. However, oil on the belt or pulley could cause an accident. In addition, belt slippage is possible during rapid infeed feed. This can result in costly equipment repairs. The gear train (reducer) guarantees slip-free operation, however, it is accompanied by perceptible vibrations, which leads to accelerated wear and chipping of the working part of the cutting tool.

    Miter saw design

    The basis of the machine, of course, is the electric drive (motor), the miter saw blade itself (for metal or wood), the table (footboard) and the handle.

    The engine start button is located, as a rule (on most models), on the step. The handle is necessary to act on the disc and provides the necessary feed force of the tool.

    Various tool steels and alloys can be used to make a metal disc for a miter saw. However, all of them must have increased wear resistance and resistance to fatigue failure. In addition, a significant amount of thermal energy is released during operation, which leads to significant heating of the tool. Therefore, these materials must also be heat-resistant and retain high properties even at elevated temperatures. Where there is a lot of heat, there is also a large linear expansion. This feature should also be taken into account when choosing the design and material of a metal blade for a miter saw.

    Choosing a blade for a miter saw for metal

    210-315 millimeters. the range of the outer diameters of the discs. The inner diameter (bore) is standard and is 30 millimeters. The tool can be easily changed as needed. Experts recommend buying a set of discs of various diameters at once. This will make it possible to use the resource of the tool as efficiently as possible and select the optimal modes of material processing.

    When choosing a disc, it is necessary to take into account the material for which it is intended. As a rule, this information is indicated by the manufacturer on the packaging of the instrument.

    In addition, not every disk can be installed on certain machines. In other words, in some cases there are restrictions on the diameter of the saw to be installed. If you ignore the recommendations from the manufacturer, the electric motor may burn out.

    Of course, there should be no damage to the surface of the tool. Any pothole or even a scratch can serve as a destructive stress concentrator. Such a disk can simply collapse in the process of work and cause injury to the worker.

    Electric drive types

    The electric drive can be either a collector type or an asynchronous one. All other things being equal, preference should be given to asynchronous. According to experts in the field of electrical engineering, such devices are unpretentious to operating conditions and more reliable, which means they will not require expensive repairs. The disadvantage is their higher cost. Although relatively inexpensive machines equipped with a drive of this type have appeared on the market recently.

    See also  Overview of Submersible Saws with Guide Bar

    On most models, the drive is structurally located behind the disc. Although there are also models in which the engine is located on the right or left. If so, the engine box will obstruct your view and could result in serious injury. Therefore, it is better to take machines on which the electric motor is located in the back.

    Tool manufacturers

    The most famous company for the production of metal discs for miter saws is Makita. Tools, equipment and consumables from this company have gained popularity all over the world due to their high indicators of reliability and quality. The traction function is a feature of Makita cross-cut saws. Not every manufacturer was able to implement such a constructive solution.

    It is also worth noting such manufacturers as Bosch and Interskol. Products under these brands may cost a little more. But it’s better not to skimp on quality and safety.

    How to remove a blade from a miter saw

    Saw blade. the “weapon” of your miter saw. And it depends on its quality, efficiency and purpose what kind of material you can work with with your miter saw.

    Naturally, the main material for which miter saws are used is wood of various species (soft and hard), as well as woodworking products. veneer, plywood, chipboard, etc. However, modern miter saws are increasingly used for processing other materials: plastic, plastics, laminate and even soft metals.

    With all the variety of choices, the main characteristics of saw blades intended for use specifically on end saws are diameter sizes. landing and external.

    The classic rim for most miter saws is 30 mm.

    This characteristic varies greatly depending on the manufacturer of the saw blades. Of course, there are the most common disc sizes. It. 210 mm, 216 mm, 255 mm, 305 mm.

    Important! All manufacturers of miter saws describe in the instructions for use of the equipment, which saw blade diameter is standard for a particular saw. Do not risk using discs of a non-standard diameter on your trimming! Its mechanism is designed to work with specific blade sizes, and the use of non-standard consumables can provoke severe runout, the appearance of chips and burrs along the cutting line (which is often mistakenly attributed to the poor quality of the saw blade), the curved cutting line, as well as the rapid overheating of the motor on the miter saws. The parameters of the protective cover on the unit are also designed for this, which do not just do not allow the use of enlarged saw blades.

    However, there are far more serious and less obvious differences between saw blades from different manufacturers. It. the method of their manufacture, the material of the saw blades, as well as the sharpening and geometric shape of the cutting teeth.

    Solid saw blades are not suitable even for semi-professional use. They become blunt faster, require a set of teeth, give a cut of the worst quality. Yes, practically no one produces them.

    There is also a way in which discs are made in production. For example, the highest quality discs (consider the example of Bosch) are cut from blanks exclusively using a laser. This allows for the highest possible alignment of the saw blades on the miter saw shaft, as well as the best possible balance of the blades and, accordingly, their increased durability in use. The cutting edges of the discs are also specially processed to increase their service life without the need for additional sharpening.

    Thicker teeth withstand side loads better!

    The angle of the cutting teeth is specially selected for the material to be cut.

    How to Replace the Blade on a Miter Saw–A Quick Fix

    In particular, for cutting metal tiles, plastic and aluminum, saw blades with cutting teeth are used, which have a negative angle of inclination of 5 degrees. Here it is important that the teeth have a different sharpening shape: odd. trapezoidal (for rough sawing), even. straight (for fine cutting of thin materials). Discs with the above configuration are perfect for, for example, thin laminate sheets. And for thicker ones, you will need discs with teeth of the same shape, but with a positive angle of inclination of about 15 degrees.

    For cutting wood and materials containing wood, you need blades with a positive angle of inclination and one-sided sharpening with an alternating direction. This is the most versatile type of sharpening, used for fast cutting of wood across and along the grain, cutting multi-layer composite materials or plywood. These blades give clean cuts and sharp edges in wood.

    Also, do not forget about the number of teeth on the disc.!

    For coarse sawing of construction timber, formwork with adhered residues of concrete, aerated concrete, etc., saw blades with 12-16 teeth (for example, the Bosch Construct Wood series) and a special profile with increased resistance to foreign bodies in the wood are required, i.e. concrete, nails, etc.
    For high-speed longitudinal cutting of wood, a saw blade with 20-24 teeth is sufficient. It will effectively remove sawdust and perform well on soft wood.
    Blades with 36-48 teeth are better for cross cuts and hardwood and wood-containing materials.
    If you are dealing with laminated chipboard, you need even more: 40-64 teeth. The cutting speed will decrease, the load on the saw will increase, but the cutting line will be clean.

    Remember: the more teeth a saw blade with carbide teeth has, the higher its cost, because the bulk of the price of a blade is formed just from the amount of carbide taps.

    If you have noticed, most of the saw blades from the professional category are also “decorated” with through-point slots or wavy lines. Such patterns are usually created with high-precision laser and have nothing to do with embellishment. Their functional purpose. compensate for thermal deformation in heated discs and reduce the noise level emitted by the miter saw during operation.
