The DeWalt 4.5" 20V MAX XR Brushless Paddle Switch Angle Grinder with Kickback Brake Kit (DCG413R2) delivers performance, durability, and safety in a conveniently portable tool. This cordless angle grinder features an efficient, brushless motor that requires no brush changes and offers long runtimes. The E-Clutch system senses tool motion and automatically reduces motor torque when binding or pinching is detected for maximum safety. Additionally, the Kickback Brake engages with maximum force to quickly stop the wheel and shut off the tool to reduce risk of injury and tool damage. The grinder also features a two-step on/off trigger switch that has a no-volt release function, to prevent accidental turn-on. A One-Touch Guard allows for single-action adjustments to the guard position. This kit includes two battery packs that are interchangeable with DeWalt's extensive 20V MAX system.
