Abstract

A hand tool impacting device may include a drive shaft, an impaler disk, and a floating pin positioned in an aperture of the drive shaft. Circular ramps along an outer edge of the impaler disk may interact with a stationary pin to translate the drive shaft and generate an impacting motion. A pair of springs placed against a side of the floating pin may allow a tool bit to engage or disengage the impaler disk, for selective use of translational impacting motion or rotational torque. An impact bit for engaging the impaler disk may include a tool head that may engage a work piece and a tool shaft inserted into the drive shaft to engage the floating pin.
