Milwaukee Cordless, Impact Wrench, 18V DC, 650 ft-lb Breakaway Torque

These cordless impact wrenches run on Milwaukee batteries and use impact-rated sockets to drive nuts and bolts. The batteries can also power other Milwaukee tools of a compatible series and matching voltage. 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.
