Milwaukee makes M18 FUEL die grinders in straight and right-angle configurations. The straight die grinder (2784-20) targets metalworkers. The right-angle variant (2485-20 compact, different from the large angle grinder) reaches into tight spots.
Milwaukee M18 (18V) Platform
The 2784-20 runs on M18. The 2485-20 is actually M12, which makes it lighter and more compact for detail work. Milwaukee splits die grinders across both platforms based on the use case.

Frequently Asked Questions
Straight or right-angle die grinder?
Straight for general grinding, deburring, and porting. Right-angle when you need to reach into a tight cavity or work at 90 degrees to the workpiece. Metalworkers and automotive technicians tend to own both.
Why is the right-angle model on M12 instead of M18?
Weight and size. A right-angle die grinder is a precision tool used in tight spaces. The M12 platform keeps it under 2 lbs with the battery, which matters when you're holding it at arm's length inside an engine bay.
