Milwaukee Drill: 1/2 in Chuck Size, Keyed, 1,550 RPM Max. Speed, Brushless Motor, (1) Bare Tool, 18V DC

These cordless joist and stud right-angle drills are powered by Milwaukee batteries of a compatible series and matching voltage. Also called Hole Hawg drills, they fit between studs like general purpose right-angle drills, but have higher torque to make larger holes. Tools using lower-voltage batteries are generally lighter and more compact 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. Tool batteries can also power other tools of the same brand, battery series, and voltage.
