Abstract

An impact tool includes a housing including a motor housing portion and a front housing coupled to the motor housing portion, a motor supported within the motor housing portion, a battery pack supported by the housing for providing power to the motor, and a drive assembly supported within the housing and configured to convert continuous torque from the motor to consecutive rotational impacts upon a workpiece capable of developing at least 1,700 ft-lbs of fastening torque. The drive assembly includes a camshaft driven by the motor for rotation about an axis, an anvil extending from the front housing, and a hammer configured to reciprocate along a travel portion of the camshaft between a rearmost position and a forwardmost position to deliver rotational impacts to the anvil in response to rotation of the camshaft.
