Circular saw

Changing the blade on a crosscut saw Zubr

Such a tool, as seen mitre, not everyone is familiar with. Despite the large amount of material that this tool can cut, its main purpose is specific. That’s why professional finishers often use such a saw. Not often needed at home. However, if you don’t want to overpay for repairs, it makes sense to buy all the tools you need to make the job easier.

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

The concept

Mitre saw. is a tool designed to cut evenly at a given angle. The cutting angle of the saw can be either 90 degrees or 45 degrees. Its main advantage is that it handles long parts and unusual surface shapes. A striking example of this is the floor plastic baseboard.

But this tool has other functions.

The trim saw can cut a large number of the same (specified sizes) angular and straight grooves. This is why it is necessary to choose craftsmen for making and assembling furniture and doors.

The appearance of this device resembles an ordinary circular saw (circular saw) mounted on a movable bracket. It allows the discs to drop not only vertically, but also at any angle. This tool allows you to cut different materials:

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


Saw blades have a number of basic parameters that help distinguish them.

Outer diameter is not normally a significant indicator of cutting speed. Responsible for the depth of cut. This can be determined from the inside diameter of the saw. Large wheel (305-355 mm) is not suitable for a product with a smaller body diameter. (For safety reasons, by the way, it is not recommended to remove the guard.) Most often for this kind of saw you take products with an index from 130 to 250 mm.

The inside diameter must correspond to the size of the drive shaft to which the product is attached. If it is larger, when the saw is in operation, the off-centered disc creates large vibrations, which leads to severe wear of the bearings and the shaft itself, as well as damage to the disc or its teeth. In addition, such installation is a gross violation of the rules of employment and is dangerous for humans.

Sawing speed depends on the direct proportion of the number of teeth on the blade. In addition, a large number of them gives a smoother and neater cut. But this approach has a significant disadvantage. Is an increased load on the saw’s motor. There are discs:

The angle of the teeth is very important for a quality cut. This is fixed by the deflection of the cutting edge of the tooth from the radius of the saw blade. This parameter can be:

Finally, the tooth configuration. Each shape is designed for a specific cut. This is why the tooth is highlighted here:

  • flat. longitudinal sawing at high speed;
  • trapezoidal flat (alternating high trapezoidal and low flat tines). Saws in wood, plastic and soft metals (aluminum);
  • interchangeable (teeth alternate in right and left slope). Helps you cut wood, chipboard and composites accurately in both the longitudinal and cross direction;
  • Combination (one flat tool replaces four interchangeable tools). Is absolutely versatile;
  • Interchangeable with the larger slanted side. are used for sharp materials and also for clean cutting at right angles.

As for the thickness of the sawdust itself, it determines the thickness of the cut. Standard. 3.2 mm. If it is higher, it will reduce the amount of material and, if much less, will lead to overloading of the equipment and possible deformation of the disc.

However, when working with each type of material, there are also peculiarities of accessory saws.

How to choose the right one?

Modern repairs often require a miter saw for aluminum, plastic and stone. These materials are actively used to create modern decor.

Changing the blade on a miter saw

To choose a disc for soft metals and polymers, you need to know that there is a difference in spraying a hollow structure or a dense array. The quality of the cut here depends mainly on the number of teeth. That is why it is better to use discs with more teeth to obtain a close to perfect result with hollow structures. Dense material is best cut with a notch.

changing, blade, mitre, saws

An important criterion is the thickness of the disc and the material from which it is made. Solid carbide carbide tip made of hard (high-carbon) metals. better choice. It lasts longer and is suitable for resharpening. The same cannot be said for welded teeth.

This quality is mostly characteristic of European brands. The cost of choosing an expensive brand pays off during use.

Good quality can be noted on the brands Bosch, DeWALT, Makita, CMT. These companies also make construction tools, including saws.

When it comes to angles of inclination, it must be negative for soft materials such as plastic. That gives the cleanest possible cut. The shape of the teeth is quite varied. A universal drive may be a better option. You can never go wrong with this.

Simple metal alloy is not enough for quality stone cutting. This requires harder materials, in which the role of diamond deposition. In this case, the abrasive grit size is the decisive factor in the choice. The larger it is, the less beautiful and high-quality the cut will be. A fine diamond is much more useful and cleaner. But to prevent overheating of the motor, it is better to choose not the smallest value.

It should be noted that the blade of such circles only remotely resembles teeth. Their design is more like a periodically separated monolithic cutting disk. The shape is explained by the fact that the sawing is carried out due to the friction of the abrasive on the hard stone.

Change wheel

Making repairs even at home, periodic material changes also require sawing. This is not difficult to change, but you still need to know the correct sequence for your own safety.

You have to start by putting the protective plastic cover (if there is one) in the upper position. To do this, unscrew the side auxiliary bolt, lift the structure, and then secure it with the same bolt, just in a different position.

Next, take the hexagon that unscrews the clamping bolt in the center. At the same time at the back of the saw press the button for the shaft locking mechanism, which is a stopper. It holds the shaft in motion. So, holding it in place, you can squeeze the central bolt with the hexagon socket. Then you need to unscrew the bolt (you can use your hands), remove the side limiter (similar to the wide washer), and then the disc.

Reassembly is done in reverse order. Place the blade on the shaft and then place the lock washer and screw in manually as far as it will go. To tighten the nozzle, press and hold down the button and tighten the center bolt to the edge of the hexagon.

After installing the saw blade, you can check its strength with a small slope. If there is no play, the installation is complete and you can start cutting.

The main malfunctions and their symptoms

The following are typical problems with handheld circular saws.

How to Replace the Blade on a Miter SawA Quick Fix

  • Tool does not start. The power cord, power plug, start button, or electric brushes can be faulty.
  • Tool motor is very hot. These symptoms can be caused by an inter-turn short circuit (breakage) in the armature or stator coils, as well as by too intensive operation of the machine.
  • Gearbox in the machine is overheating. Overheating in this unit can be caused by bearing failure or lack of lubrication in the gears.
  • Brushes are sparking. This is usually caused by excessive wear and tear.
  • A burning ring is visible around the motor manifold. If at work of the unit the circular spark around a collector of the engine is observed, its occurrence can cause a failure of an armature winding or a blockage of space between lamellas of a collector by graphite dust.
  • The machine does not develop the required power. Lack of power can be caused by mains drop, defective motor windings, worn electric brushes, defective start button.
  • While the machine is running, you hear a grinding noise and other strange noises. These symptoms can be caused by broken gear teeth or faulty bearings.
  • The motor is humming, but the machine is not running. Geared motor may be jammed.

How to remove the blade from the circular saw?

To remove the blade correctly, the following procedure should be followed:

  • For your own safety, you must unplug the power cord or remove the battery
  • For easier replacement you need to set the tool on a flat, hard surface
  • To unscrew the bolt, the locking spindle must be pressed down to start unscrewing
  • Unscrew the bolt with a special wrench, which is included
  • Pull out the bolt and remove the washer that holds the saw blade
  • Move the lower guide arm to raise the guard
  • Take off the sawing wheel

Types of Cutting Teeth

Type of teeth There are four planes on the tooth surfaces. a front plane, a back plane, and two side planes.

When they intersect each other they create a single cutting edge which is used to cut the surfaces.

  • Straight Tooth. Most frequently used only for making quick, longitudinal cuts. Quality and accuracy are of little importance in this type of work.
  • Tooth slanting. Its back plane is tilted to the right or left. On saws, these teeth often alternate, causing them to be called “alternate-slotted. These teeth are the most commonly used in tools. Angle size may vary due to surface finish. wood, chipboard, plastic. They are used for longitudinal and transversal movements. The large inclination angle on the tools is used when cutting double-sided laminated boards. It helps to avoid chipping of the material. The more beveled the angle, the easier it is for the saw to pass over the surface. But it greatly increases the likelihood of tooth breakage. On some products, the teeth are not only beveled at the back, but also at the front.
  • Trapezoid tooth. The main advantage of this type is that the edge blunts slowly. But they are rarely used alone, usually alternating with straight teeth. During operation, the trapezoidal teeth are above the straight ones, so they do the basic (rough) work of sawing. The straight teeth do the finishing work. Saw blades of this design are used for cutting plastic, chipboard and fiberboard.
  • Conical tooth. This type of tooth is considered supplementary because it only helps to cut the bottom of the material (most often laminate). This design helps to protect the surface from chipping and cracking. Bevel gears usually have straight front edge, but it can also be concave. This type is used for finishing a cut.

Important! Each type of tooth needs to be sharpened properly. Not allowed to be sharpened at the same angle.

Crosscut, circular, circular saws repair

Circular saws are used for cross and slash cuts in wood, plywood, hardboard, fiberboard, PVC, metal, slate, plexiglass. The first bandsaw for household use was presented by AEG. Modern circular saws are multifunctional solutions that are used for construction and household works. Leading manufacturers of such tools Hitachi, Bosch, Makita, Husqvarna, Metabo.
