A pneumatic impact tool includes a handle, a work attachment coupled to the handle, an inlet and an outlet permitting air flow through the tool to drive the tool. A motor assembly is functionally positioned between the inlet and the outlet, the motor assembly having a rotor driven by the air flow, and the motor assembly defining a longitudinal motor axis about which the rotor rotates. An output drive is connected to the motor assembly to selectively rotate the output drive in response to rotation of the rotor. The output drive defines a longitudinal output axis about which the output drive rotates, such that the longitudinal output axis is substantially perpendicular to the longitudinal motor axis. An impact mechanism is functionally positioned between the motor assembly and the output drive, such that the impact mechanism drives the output drive with impact forces in response to rotation of the rotor.
