Injuries caused by the angle grinder are the responsibility of the surgeon and are not always treatable. This article will skip the horror of severed fingers and get to the essentials. safety precautions that are not always found in standard instructions. But first things first.

For what is used an angle grinder?

This sharp cutting tool is essential when working with stone, metal, concrete. The device also copes well with marble, granite, other rocks. Can be used in any area of activity, but most often the angle grinder is found:

• in the hands of a plumber. he uses it to cut pipes, to remove rust from their surface;

• In the operations of the Ministry of Emergency Situations. angle grinder cut cars after an accident, open access to the room in case of fire, etc.

From the angle grinder a lot of dust, in addition, in all directions fly sparks and small fragments of the material to be cut. Therefore, the first rules when working with the angle grinder. a special shield (protection on the disk mechanism itself) and gloves made of fireproof material.

Design and capabilities

All angle grinders, regardless of manufacturer, are made the same. The difference may be additional design elements, due to which the brand wants to stand out. The standard grinder, (for example, Makita GA5030) consists of:

• a rugged, impact-resistant housing that is not afraid of falls;
• an electric motor with rotor, stator and electric brushes
• gearbox and clutch;
• two handles for holding the machine;
• a lever for quick disc replacement
• the button that starts the motor.

Often this button works very smoothly, allowing the angle grinder to gradually pick up the pace, thus reducing the load on the motor and reducing the risk of possible injury.

The functionality of the angle grinder depends on the size of the machine itself and the diameter of the disc. So, if you need to perform a large amount of work, for example, to grind a large area of concrete, you need to select the disc with the maximum diameter (specified in the technical specifications of a particular model). There are also universal cutters: almost all angle grinder can work with an attachment for the inner diameter of 22-23 mm.

Important: the larger the disk, the slower its rotation, that is, the work itself takes longer. True, modern tools are equipped with the ability to regulate the number of revolutions. This functionality is especially useful when cleaning or sanding surfaces.

What are the dangers of an angle grinder?

Getting one of these particles in the eye could permanently blind you. The goggles should be of the closed type and fit snugly over the face. If you replace them with a mask, it would be perfect.
• Failure to use the blade guard. During contact with the surface, the working wheel is sometimes destroyed. In this case the element breaks into small parts. The safety cover gives direction to this flight and directs the splinters away from the employee.
• Respirator when working with stone materials. When the angle grinder cuts stone, concrete, marble, a lot of dust is created, which the operator has to inhale. Dust does not only choke the respiratory tract but also enters the throat. All this is dangerous for health, so it is better to be reinsured, using protection devices.

Often work clothes are loose fitting. That’s for comfort, so you don’t have to restrict your movements. But when working with an angle grinder such a robe should be refused, because the wide pants can hit the rotating disc. It will quickly “jam” the fabric and injure the body. Lightweight outfits with exposed arms and legs are also taboo.

• use discs for purposes other than those for which they are intended, for example, grinding with a disc that is too thin.

Cut material with angle grinder must be at a right angle, there must be no tilting. the cutting line for the trimmer must be at the side of the operator. In this case, even during the jamming of the angle grinder machine will “twitch” to the side, and the worker will remain unharmed.
