Abstract
An impact tool includes a housing extending along a longitudinal axis, the housing including a motor housing portion and a front housing coupled to the motor housing portion, a motor supported within the motor housing portion, and a drive assembly supported within the housing. 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. An axial distance between the forwardmost position and the rearmost position of the hammer is at least 20.75 millimeters, and the travel portion of the camshaft has a diameter of at least 25 millimeters.
