Complete high-powered applications in tight spaces with the ATOMIC™ 20V MAX* 4 in. Angle Grinder (battery and charger sold separately) that delivers optimized maneuverability and 755 MWO. 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 access to ultra tight spaces, while the clip-on guard can quickly convert a Type B guard into a Type A guard. Replace pneumatic angle grinders with this cordless solution that delivers untethered performance, productivity, and pneumatic-like power.
