Product details

Complete high-powered applications in tight spaces using the ATOMIC™ 20V MAX** die grinder with lanyard ready attachment point (battery, charger, and lanyard sold separately). This tool is equipped with the DEWALT® anti-rotation system to help maximize control. This feature quickly stops the wheel when a pinch, stall, or bind-up event is sensed, reducing reactionary torque. An ergonomic design allows this tool to access ultra tight spaces. Featuring a lanyard ready attachment point, up to 445 MWO, and a maneuverable design, this grinder is ideal for working at height. Replace pneumatic die grinders with the ATOMIC™ 20V MAX** die grinder with lanyard ready attachment point that delivers untethered performance, productivity, and pneumatic-like power† . Battery & charger sold separately.
