Abstract
A hand held power tool has a housing, a motor, a power source, a cam shaft, a hammer, an integrated anvil-gear, a second gear, and an output. The motor is disposed in the housing and has a motor axis. The power source energizes the motor. The cam shaft is driven by the motor and the hammer is driven by the cam shaft. The integrated anvil-gear has an anvil end and a first gear end, and the anvil end is impacted by the hammer. The second gear engages the first gear end and defines an output axis that is at a predefined angle with respect to the motor axis. An output is coupled to the second gear.
