Product details
The Milwaukee 3487-20 is an M12 FUEL 1/4 IN extended die grinder built for service technicians who need to reach past obstructions a standard grinder can't clear. The 4 IN extended shaft puts the collet deep into frames, brackets, and engine bays, while the POWERSTATE™ brushless motor spins accessories up to 20,000 RPM — no air hose or compressor required.
Four-mode speed control and a variable-speed paddle let you match the tool to the accessory, from a 2 IN cut-off wheel to a 3 IN sanding disc. A shadowless LED keeps the work lit, and a push-button spindle lock makes accessory changes a single-wrench job. Sold as a bare tool.
