ABSTRACT:
A tool for removing broken threaded fasteners such as seized or damaged Budd nuts mounted on a stud extending from the hub of a dual wheel assembly. The tool includes a base plate which is securable at the Budd nuts adjacent the broken nut by stand-off and fasteners. A cutter is advanceable by a pivotal bar by means of a manually operable adjustment knob. The cutter is rotatable in a busing and has a cutting head with a bore which extends over the damaged nut. Replaceable cutting teeth are carried on the cutting head and when advanced cut through the flange on the damaged Budd nut. The device can be powered by a power tool attachable to the device. A depth guide is provided to assist the mechanic in correctly determining the proper depth of cut. As the cutting head is advanced, the flange portion of the Budd nut is cut away so the inner wheel rim can be removed from the hub and thereafter the remaining shaved Budd nut can be easily removed.
