An angle impact tool includes a handle assembly extending along a first axis, a prime mover in the handle, an output shaft rotatable about the first axis, and a work attachment connected to the handle assembly. An output drive is supported in the work attachment for rotation about an output axis perpendicular to the first axis. A gear assembly including a spur gear is positioned within the work attachment to transfer torque from the prime mover about the first axis to the output drive about the output axis. An impact mechanism is positioned within the work attachment and includes a hammer and an anvil. The hammer rotates under the influence of the prime mover and is operable to periodically deliver an impact load to the anvil. The output drive rotates about the output axis under the influence of the impact load being transmitted to the output drive by the anvil.
