Milwaukee 3672-20 M18 FUEL™ 4-1/2"-6" Variable Speed Braking Grinder, Paddle Switch w/ ONE-KEY™
Infinite Versatility. Industrial Power. Smart Management.
The Milwaukee 3672-20 M18 FUEL™ 4-1/2" – 6" Variable Speed Braking Grinder is engineered for the professional who demands ultimate control over every cut and grind. Delivering the performance of a 13-amp corded grinder, this tool is powered by the POWERSTATE™ Brushless Motor, providing up to 9,000 RPM. The 5-step variable speed dial (3,500 – 9,000 RPM) allows you to slow the tool down for specialized tasks like stainless steel finishing and polishing, or ramp it up for aggressive material removal.
This model is equipped with ONE-KEY™ technology, the industry’s first cloud-based inventory management platform. This allows you to track the tool's location, manage its lifecycle, and even lock the tool out remotely if it is lost or stolen. Safety is further enhanced by the RAPID STOP™ Brake, which stops accessories in under 2 seconds, and an Electronic Clutch that prevents kickback during bind-ups. With its 6-inch capacity, this grinder provides a deeper depth of cut than any standard small angle grinder on the market.
