ABSTRACT:
An extractor for removing a broken bolt stud having a pre-drilled bore from a threaded bore including a cylindrical body having a drive head on one end and expander on the opposite end. A collet is movably attached to the cylindrical body by threads permitting lateral movement of the expander against the gripping means causing them to expand and engage the pre-drilled bore. Rotation of the expander permits removal of the broken bolt stud due to the friction between the extractor and the stud.
