Abstract
An impact wrench is provided with a battery to power the motor. The impact wrench provides improved portability since the impact wrench does not need to be connected to an electrical extension cord or a pneumatic hose. The output drive, motor, batteries and main handle may be aligned along the axial direction of the tool. The batteries may be located between the motor and the main handle.
