Complete metal and concrete cutting projects, wire brushing, and more with the 60-Volt Maximum 7 in. Brushless Cordless Grinder with Kickback Brake Kit. Delivering as much as 2,300 unit watts out, this grinder produces up to 30% more torque than the DCG418 60-Volt Maximum Grinder. With a maximum output of 3 HP, you can power through heavy-duty grinding jobs with ease using its no-load speed of up to 6,500 RPM. Built with user protection in mind, the Perform and Protect grinder’s kickback brake engages to rapidly shut the grinder off when a stall, bind-up, or pinch is detected.
