The Milwaukee M18 FUEL 4-1/2"–5" Braking Grinder with ONE-KEY Paddle Switch is built to deliver corded-level performance in a fully cordless design. Producing power comparable to an 11-amp grinder, it is engineered to handle demanding grinding and cutting tasks with speed and control.
At the core is the POWERSTATE™ Brushless Motor, delivering consistent output at 8,500 RPM for faster material removal and increased jobsite productivity. REDLINK PLUS™ Intelligence optimizes communication between the tool and battery to provide advanced performance, thermal protection, and long-term durability.
For enhanced safety, the grinder features a RAPIDSTOP™ braking system that stops accessories in under two seconds when using an abrasive disc. An electronic clutch helps reduce kickback, while built-in overload protection extends motor life. The ergonomic paddle switch design, paired with an anti-vibration side handle, improves comfort and control during extended use.
This grinder is ONE-KEY™ enabled, allowing users to connect wirelessly to a smartphone for tool tracking, inventory management, and usage visibility across multiple job sites. Tool-free guard adjustments and FIXTEC™ nut technology allow quick accessory changes, keeping workflow efficient.
