20-Volt Max Lithium Ion Cordless 5 in. Flathead Small Angle Grinder Kit with Kickback BrakeThe DEWALT Flathead Paddle Switch Small Angle Grinder is brushless, so there is no need to change old brushes, and it ensures a longer motor life. Its break stops the wheel in 2 seconds or less when the switch is released. It also features a Kickback Break that engages maximum force to stop the wheel when there is a pinch, stall, or bind up to reduce kickback. The grinder will also shut off in those events to further protect the user. California
