  • Patent number: 4323131
    Abstract: A removable anti-wear insert adapted to be mounted in the bore of a tool body, the insert being removable after wear with minimal damage to the tool body. The removable insert has a bore therein mounting an extractor sleeve, the sleeve having a threaded portion. Upon sufficient wear, the extractor sleeve threaded portion is exposed so that a set screw already mounted therein, or a separate bolt, can be rotated inwardly into engagement with the bottom of the tool body bore to force the insert upwardly out of the tool body bore. The head of the bolt threadedly mounted in the extractor sleeve shaft within the insert bore can be used as a point of leverage for pulling the insert out of the hole.
