Dewalt 4-1/2" 20V MAX Cordless Angle Grinder Kit, 20.0 Voltage, 8000 No Load RPM, Battery Included

These angle grinders are powered by DEWALT batteries of a compatible series and matching voltage. The batteries can also power other DEWALT tools. Tools using lower-voltage batteries are generally lighter and more compact but less powerful than tools using higher-voltage batteries. Tools using lower-capacity (Ah) batteries are less bulky but store less power than tools using higher-capacity batteries.
