ABSTRACT:
A tool for removing broken threaded fasteners such as a seized or damaged lug mounted on a stud extending from the hub of a dual wheel assembly. The tool includes a pilot member having generally cylindrical exterior surface which defines an axially extending threaded bore engageable with the stud extending through the broken lug. A cutter member has a body defining a guided bore which is engageable about the exterior of said pilot member and is rotatable by means of a power tool. When the cutter member is advanced at least the flange portion of the lug nut is cut away so that the inner wheel rim can be removed from the hub and thereafter the remaining shaved lug nut can be removed.
