The Milwaukee M18 FSAGSVO125X-502X is a battery-powered angle grinder designed for professional applications that require variable speed control and extended runtime. This 125 mm angle grinder operates on the M18 18V battery platform and includes a 5.0 Ah high-capacity battery for longer use between charges. The variable speed function allows for adjusting the rotation from 2,800 to 8,500 RPM to meet specific material requirements and applications. Built with a durable metal gear housing and concealed components, this tool is designed for demanding work environments where reliability is essential. The grinder features a spindle lock for easy disc changes and a safety clutch mechanism that disengages the disc if the tool gets blocked, reducing kickback. With an ergonomic design that includes a rubber overmold on the main handle and auxiliary handle, it offers comfortable handling during extended use. The tool measures approximately 370 mm in length and weighs 2.1 kg without the battery, providing a balanced feel for precise control. Compatible with all M18 batteries, this angle grinder is suitable for cutting, grinding, and fabrication work on metal, stone, and other materials. The electronic brake function stops the disc quickly after the trigger is released for increased safety. Designed for professional tradespeople in construction, metalworking, and manufacturing, this battery-powered angle grinder delivers the power and runtime for continuous operation without cable restrictions.
