Brushless angle grinders are the better choice for heavy use. They produce less heat, have longer service life and save battery power. For professional jobs, pick 21V brushless cordless angle grinder.

## 2. Disc Size Selection

100mm is the most popular size. It is compact, easy to handle, perfect for workshop metal cutting, weld grinding and surface polishing. Larger discs are for heavy industrial cutting.
