High Capacity cordless grinding system with extended runtime configuration
The Milwaukee M18FSAG115X-502B FUEL 115 mm Angle Grinder delivers corded-equivalent performance comparable to a 1200 W grinder. Operating at a no-load speed of 8,500 rpm, the POWERSTATE brushless motor maintains consistent cutting and grinding performance across steel, stainless steel, and masonry applications.
The slide lock-on switch supports controlled continuous operation during extended cutting and grinding tasks. The FIXTEC system enables tool-free wheel changes, while the 115 mm keyless guard allows rapid adjustment without additional tools. Anti-kickback protection enhances operational safety, and the line-lock-out function prevents automatic restart after power interruption. The twin 5.0 Ah REDLITHIUM batteries provide balanced runtime for sustained jobsite use, and the 16″ contractor bag ensures practical transport and storage.
