    Abstract: An impact tool includes a housing extending along a longitudinal axis. The housing includes a motor housing portion, a first handle extending from the motor housing portion, and a front housing coupled to the motor housing portion opposite the first handle. The impact tool also includes a motor supported within the motor housing portion, an anvil extending from the front housing, an impact mechanism supported within the front housing, and an auxiliary handle assembly. The auxiliary handle assembly includes a mount coupled to the housing, an auxiliary handle coupled to the mount and spaced from the first handle, and an adjustment mechanism. Loosening the adjustment mechanism permits rotation of the auxiliary handle assembly about the longitudinal axis relative to the housing, and tightening the adjustment mechanism secures the auxiliary handle assembly in a selected rotational position.

    Abstract: An impact tool includes a housing, an electric motor supported within the housing and having a motor shaft, and a drive assembly configured to convert a continuous rotational input from the motor shaft to consecutive rotational impacts upon a workpiece. The drive assembly includes a camshaft having front and rear portions. A gear assembly is coupled between the motor shaft and the drive assembly, the gear assembly including a ring gear that is rotationally and radially fixed relative to the housing and a plurality of planet gears meshed with the ring gear. Each of the plurality of planet gears is coupled to the rear portion of the camshaft, and a line of action of a radial load exerted by the rear portion of the camshaft on the housing passes through one of the plurality of planet gears and the ring gear.

    Abstract: An anvil for use with an impact wrench includes a first end, a second end opposite the first end, a shank adjacent the first end, and a head adjacent the second end. The shank includes a diameter and an outer cylindrical surface that defines a longitudinal axis that extends centrally through the anvil between the first end and the second end. The head includes a plurality of planar faces and an outer cylindrical surface. The outer cylindrical surface defines a diameter of the head. A ratio between the diameter of the shank and the diameter of the head is between approximately 1:1 and approximately 1.35:1.
