Abstract
A hand tool impacting device may include, a drive shaft with an aperture, an impaler disk, and a floating pin positioned within the aperture of the drive shaft. A set of circular ramps on the outer edge of the impaler disk may interact with a stationary pin insert to translate the drive shaft and create an impacting motion. A pair of springs placed against either side of the floating pin may allow a specialized tool bit to engage or disengage the impaler disk, thereby allowing selective use of translational impacting motion, or rotational torque. An impact bit for engaging the impaler disk may include, a tool head configured to engage a work piece and a tool shaft configured to be inserted into a hollow drive shaft to engage a floating pin. According to one embodiment, the impact bit includes a number of sleeves to guide the tool head during operation.
