Milwaukee M18 FUEL 4-1/2 in. / 5 in. Grinder, Paddle Switch No-Lock Kit

Model number
2780-22

The Milwaukee M18 FUEL 4-1/2 in. / 5 in. Grinder, Paddle Switch No-Lock Kit is a cordless 4-1/2 in. / 5 in. angle grinder aimed at grinding, surface prep, and cutoff work where cord management slows down production. Milwaukee lists an 8,500 RPM top speed, a 5/8"-11 arbor, and a bare-tool weight of 5.8 lb with an overall length of 15 in. The POWERSTATE Brushless motor, REDLINK electronics, tool-free guard adjustment, and anti-vibration design are intended to keep output high in fabrication and jobsite metalworking. Milwaukee positions it as a cordless replacement for everyday corded grinder tasks. This kit version adds batteries and a charger so it can go straight to work on the M18 platform.
