Abstract

An attachment for an impact hammer for translating the hammer's typical forwardly directed impact force into a rearwardly directed pulling force while still allowing the user to maintain a conventional orientation of the hammer relative to the work piece intended to be pulled. The attachment comprises a housing defining a cavity with a hammer bit axially movable therein and having an impacting head urged rearwardly by a bias structure which responds to a forward impact force by the impact hammer to cause the hammer bit head to exert impact force on the work piece in a rearward direction.
