Abstract
A cutting element of the type which is pushed into a preformed hole of a drill bit by means of a pusher tool. The cutting element comprises a generally cylindrical stud having an inclined support face adjacent a forward end of the stud. A polycrystalline diamond substance is disposed on the support face. A non-circular tool recess is formed in the forward end of the stud and behind the support face and is configured to receive a pusher tool for confining pushing forces to the region of the recess as the cutting element is pushed into the preformed hole. The cutting element can also be rotated by the tool for repositioning the cutting element after installation, or loosening the cutting element to facilitate its removal.
