A rotary hammer includes a motor. A controller controls operation of the motor. A trigger is moveable between an off position and an on position. A switch is in communication with the controller. The switch is movable between an activated state and a deactivated state. In the activated state, the controller operates the motor at full power independent of the position of the trigger. In the deactivated state, the controller operates the motor at a variable speed based on the position of the trigger between the off position and the on position.
