1、Function

Practical angle grinder, first of all, from a practical point of view, it is best multi-functional, multi-functional angle grinder generally need to have grinding, polishing, cutting three functions in one, and at the same time can be stone, wood, metal, glass and other materials cutting, polishing, grinding, etc.

2、Appearance

The appearance of the choice of color, that is personal preference, but the design, compact shape, the use of lighter angle grinding surface is often more popular, bring out to work, will not feel cumbersome. Therefore, many engineers like to choose lightweight, compact and practical angle grinder, so that in the process of use will also be more smooth.

3、Power

Power is the heart of the angle grinder, power size, is a key factor in directly determining its efficiency, high speed, high power angle grinder is of course more practical, fast, easy to use, in addition to high-power angle grinder heat dissipation effect will be better, can continue to work for a long time, will not appear to burn the phenomenon.

4、Safety protection

Using the machine, the biggest point is to pay attention to safety, good machine running normally, will be safer, but in addition to the protection of normal operation is not enough, but also to be careful of noise and dust damage to the human body, so choose a small noise, three-dimensional dustproof angle grinder is more conducive to health, while the angle grinder with protective cover, can also prevent dust into the machine, more can extend the service life of the machine.
