A bit extracting tool, used to pull rotatable cutting bits from bit pocket holders. The bit extractor tool comprises two concentric pipe sleeves: an inner tension sleeve with fingers to slide over and hook the rotatable cutting bit's exposed annular ring at the bit end, and a threaded hole at the pulling end which receives the tension bolt; a tension bolt which, when tightened, pulls the tension sleeve away from the pocket and pushes on the capped pulling end of the outer compression sleeve; and, a compression sleeve, open on the bit end which pushes on the face of the pocket holder surface, is capped on the pulling end to bear the force of the tension bolt as it pulls the inner sleeve, and locks the finger hooks into the annular bit ring, which tow the bit out of the bit pocket. |
