Miter saw - a tool that is not familiar to everyone. It can be used for a large number of materials, but at home it is not needed so often. The saw is mainly used by professional finishers. But if you plan to repair on your own, then it makes sense to acquire this tool as well to facilitate the process.

In addition to mastering the work with the device, you need to understand its consumable spare parts. The main of these elements is the cutting disc.

How to replace
During repair, it may be necessary to remove the saw blade. This is easy to do if you know the correct sequence of actions. It is important to read it for your own safety.
The replacement process begins with the installation of a protective cover made of plastic (if any) in the upward position. To carry out this manipulation, you should unscrew the side auxiliary bolt, raise the structure, and then fix it with the same bolt, but in a different position.

Then:
- a hexagon is taken to unscrew the clamping bolt in the center;
- at the same time, the button of the locking mechanism of the shaft is pressed on the back of the tool - it acts as a stopper and prevents the shaft from moving;
- holding the button, it turns out to press the central bolt with a hexagon;
- then the bolt is unscrewed - it is easy to do it by hand;
- the side stopper is removed (looks like a wide washer) and then the disc.
Installation is the reverse sequence of actions. The disc must be put on the shaft, then put the lock washer, then screw the bolt with your hands until it stops. To clamp the nozzle, you should press the button and hold it, while tightening the central bolt to the limit using a hexagon.
Having made the installation of the saw blade, you should check the strength of the fixation. This is done with a slight longitudinal wobble. If there is no play, then the installation was carried out correctly. You can start cutting.
How to choose the right drive
To create a modern decor, aluminum, plastic, stone are often required. Based on this, disks are more often needed to work with such materials.

Their choice for soft metals and polymers is different. Sawing a hollow or solid structure requires a different number of teeth on the blade. In the first case, a consumable part with a large number of teeth is needed, in the second - a small one.
The material and thickness of the disc are also important. The best choice is an all-alloy nozzle, the raw material for which is a hard, high-carbon metal. Such a consumable spare part can be used longer and is suitable for re-sharpening. The latter is not possible if the teeth are welded.
High quality is typical mainly for European brands. The price of their products pays off in the process of operation.
Another indicator to consider when choosing is the angle of inclination. For plastic, it should be negative, which allows you to achieve maximum cleanliness of sawing.
The shape of the teeth can be different. It is optimal to choose a universal disk. So you won't make mistakes.
A high-quality cut of a stone is possible if there is a diamond coating. The decisive factor in the choice is the grain size of the abrasive. For a beautiful and high-quality cut, it should be smaller. However, in order to avoid overheating of the engine, it is still better to prefer not the smallest size.
The blade of such circles is vaguely similar to ordinary teeth. Their design looks like a monolithic canvas, divided at a certain distance. The shape is due to the fact that sawing is performed by rubbing the abrasive against the hard surface of the stone.
