Milwaukee M18 FUEL 18V Cordless 4-1/2" / 5" Angle Grinder Bundle (2780-20) | Used - Tested | Includes Charger & 2 Batteries | Paddle Switch No-Lock

Power through heavy cutting, grinding, and fabrication work with this high-performance, jobsite-ready Milwaukee M18 FUEL brushless angle grinder kit.

Don’t get slowed down by a bare tool. This used Milwaukee M18 FUEL Cordless 4-1/2" / 5" Angle Grinder (Model 2780-20) comes as a complete, ready-to-work setup featuring two M18 RedLithium batteries and a compatible charger. Driven by a premium POWERSTATE brushless motor, this tool provides real corded-like power, delivering up to 8,500 RPM for your toughest surface prep, weld cleaning, and metal fabrication tasks without ever wrestling with an extension cord.

Engineered with a high-comfort, no-lock paddle switch, this grinder naturally improves user control and enhances shop safety by instantly cutting power the second the trigger is released. Built with advanced REDLINK PLUS electronic intelligence, the grinder dynamically protects itself from overloading or overheating under intense pressure. Because high-torque grinding can drain batteries quickly, having two packs included means you can seamlessly keep one on the multi-voltage charger while running the other—safeguarding your productivity and keeping downtime to an absolute minimum.
