Milwaukee M18 FUEL 4-1/2 in. - 6 in. Braking Grinder, Slide Switch

Model number
3671-20

The Milwaukee M18 FUEL 4-1/2 in. - 6 in. Braking Grinder, Slide Switch is a cordless angle grinder for metalworking tasks where users prefer a slide-switch control layout instead of a paddle switch. Milwaukee lists a POWERSTATE Brushless motor, 14.75 in. length, 5.3 lb bare-tool weight, and barrel-grip body sized for heavier-duty grinding and cutoff work. The braking function helps reduce wheel coast-down time after shutoff, while the 4-1/2 in. to 6 in. capacity gives it broader accessory range than a compact grinder. This bare-tool version is intended for existing M18 users.
