    Abstract: A rotary impact tool including a motor having a motor shaft that produces a rotational output to drive a gear assembly and a drive assembly driven by the gear assembly. The drive assembly including a hammer coupled to the motor shaft and an anvil configured to receive an impact from the hammer. The rotary impact tool includes a torque stick coupled to the anvil and configured to limit the amount of deliverable torque to a workpiece in accordance with a torsional stiffness of the torque stick, a position sensor to detect angular displacement of the anvil, and a controller in electrical communication with the position sensor. The controller calculates torque delivered to the workpiece from the impact by multiplying the torsional stiffness of the torque stick and the signal from the position sensor, and control the motor based on the torque delivered to the workpiece.

    Abstract: A rotary power tool assembly including a rotary power tool and an accessory. The rotary power tool includes a rotatable spindle and a first mating member. The accessory includes a housing, a hub configured to be coupled to the spindle, a ball detent disposed selectively engageable with the spindle to axially lock the accessory to the power tool, and a sleeve axially slidable between a first position in which the sleeve biases the ball detent radially inward and into engagement with the spindle, and a second position in which the ball detent is disengageable from the spindle to release the accessory from the rotary power tool. The accessory further includes a second mating member received within the sleeve and axially fixed to the arms of the housing. The first and second mating members rotationally fix the accessory to the rotary power tool.

    Abstract: An accessory for use with a rotary power tool having a rotatable spindle and a first mating member. The accessory includes a housing having a body and a plurality of arms extending therefrom, a hub selectively engagable with the spindle to lock the accessory to the power tool, and a sleeve slidable along the arms between a first position and a second position, where the sleeve includes a plurality of apertures through which the corresponding plurality of arms extend. When the sleeve is in the first position the sleeve locks the hub to the spindle to secure the accessory to the power tool, and wherein when the sleeve is in the second position the sleeve disengages the hub from the spindle to release the accessory from the power tool.
