Abstract: An impact tool includes a housing that includes a motor housing portion, a front housing portion coupled to the motor housing portion, and a D-shaped handle portion extending from the motor housing portion in a direction opposite the front housing portion. The impact tool includes an electric motor supported in the motor housing portion, a battery pack supported by the housing for providing power to the motor, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece capable of developing at least 1,700 ft-lbs of fastening torque.

Abstract: An impact tool includes a housing, an electric motor supported in the housing, and a drive assembly for converting a continuous torque input 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 an anvil rotatable about an axis and having a head adjacent a distal end of the anvil. The head has a minimum cross-sectional width of at least 1 inch in a plane oriented transverse to the axis. The drive assembly also includes a hammer that is both rotationally and axially movable relative to the anvil for imparting the consecutive rotational impacts upon the anvil, and a spring for biasing the hammer in an axial direction toward the anvil.

Abstract: An impact tool includes a housing with a first and second housing portions and a first handle extending from the first housing portion, a motor supported in the housing, a battery receptacle is located at a bottom end of the first handle, and a battery pack removably coupled to the battery receptacle to provide power to the motor. The impact tool also includes a trigger located on the first handle to selectively energize the motor, a gear assembly, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece such that the drive assembly is capable of developing at least 1,700 ft-lbs of fastening torque. A gear support is coupled to the first housing portion and the second housing portion and defines a gear case with the second housing portion to enclose the gear assembly and the drive assembly.
