DEWALT 4.5-in 20-Volt Max Cordless Angle Grinder (Battery Not Included)

This brushless small angle grinder requires no time changing brushes, and offers a longer motor life. It offers a high level of protection. Its brake stops the wheel in 2 seconds or less. The Kickback Brake 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.
