Overview
A braking mechanism stops the wheel quickly after release on this Milwaukee M18 FUEL angle grinder, which also has variable speed control. The body is metal and plastic in an angled layout for cutting and grinding.
Variable speed lets the user slow down for delicate work, and braking stops the wheel sooner for safer wheel changes. The power source entry is garbled and the weight entry conflicts with the size, so details need checking.
Who it's for
Cutoff and grinding jobs in the field where a cord is a nuisance suit a battery grinder with speed control. A shop user with a cord nearby can save by buying a corded model.

Performance notes
A braking circuit stops the wheel quickly after the trigger is released, which shortens the time a spinning disc is exposed, and variable speed matches the wheel to the material. Battery capacity decides how long the grinder runs under load.
