DeWalt DCG405B 20V MAX XR 4.5" Slide Switch Small Angle Grinder (Bare Tool) This brushless small angle grinder requires no time changing brushes and offers a long motor life. Part of the PERFORM AND PROTECT line of products, this grinder is equipped with Kickback Brake which engages with maximum force to stop the wheel when a pinch, stall, or bind-up is detected. Power Loss Reset prevents accidental restarts following a power disruption when the tool is left in the "on" position.
