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.

Abstract: An impact tool includes a housing including a front housing coupled to a motor housing portion, a motor supported within the motor housing portion, a battery pack supported by the housing for providing power to the motor, the battery pack having a nominal capacity of five Amp-hours and a nominal output voltage of at least 18-Volts, 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.
