Selection Guide

A professional tool must have a number of advantages, among which are reliability, durability and high performance.

Applicable materials. First of all, when choosing a professional angle grinder, you should find out what materials the critical parts are made of.

1. One of the most loaded nodes is the gearbox. The more parts made of non-ferrous and ferrous metals (and alloys) in it, the slower the assembly will wear out, respectively, and the service life of the grinder will increase.
2. For a comfortable grip, as well as to reduce vibration, rubber pads are widely used in professional grinders. They serve for a long time without being erased during active work.
3. Brushes become consumables in a grinder with frequent use. When choosing a tool, you should determine how accessible the brush assembly is. If the brushes are easy to remove, you can change them yourself.

Performance. In order to do a lot of work during a shift, an angle grinder must be high-performance.

1. In large models, this is achieved by installing a powerful electric motor (2.4-2.6 kW).
2. Compact grinders provide the necessary performance due to the high rotation speed (10000-12000 rpm).
3. Important additional features. With constant work with the grinder, some special mechanisms and systems become necessary.
4. For safety reasons, the angle grinder must have a safety clutch to help keep the operator healthy in the event of a disc jam.
5. Professionals will also need a button lock to prevent accidental activation.
6. Anti-vibration systems, soft start, and maintaining the speed under load help to reduce operator fatigue during long-term work.

Equipment. The professional tool is completed with a number of accessories.

1. An additional handle is required for a secure grip of the grinder with two hands. It should be multi-position, preferably in anti-vibration design.
2. A protective cover becomes a mandatory accessory; it must protect a person from sparks and abrasive.
3. Most professional angle grinders are equipped with a keyless tool lock. If the discs are clamped with traditional nuts, a special wrench must be included.
4. Since the craftsmen have to constantly move around different objects along with the grinder, it is very convenient to store the tool and equipment in a case. It must be sufficiently roomy and durable.
