ATOMIC 20V MAX 4.5" Angle Grinder (Tool Only)

Complete high-powered applications in tight spaces with the ATOMIC 20V MAX 4.5-in Angle grinder (battery and charger sold separately) that delivers optimized maneuverability and up to 760 MWO. This unit is equipped with the DEWALT PERFORM & PROTECT 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, while the clip-on guard can quickly convert A Type B guard into A Type A guard.
