This DEWALT small angle grinder features a brushless motor for an extended motor life and no need to change out old brushes. The grinder's wheel stops within 2 seconds or less. And, its Kickback Break engages maximum force to stop the wheel when there is a pinch, stall, or bind-up to reduce kickback, and will shut off for further protection. | DEWALT 5" 20V MAX XR Flathead Paddle Switch Small Angle Grinder (Tool Only) DCG413FB
