Abstract
A cutting element includes a stud having an inclined supporting surface. The supporting surface intersects a side surface of the stud to form an edge. A cutting member is bonded to the supporting surface. A reinforcing shoulder projects from the supporting surface adjacent a rear portion of the cutting member. The shoulder includes a side surface, a portion of which intersects the edge along a region of the edge whose forwardmost point is spaced rearwardly from a rearwardmost point of the cutting member. When the cutting element is positioned within a bore of a drill bit, that region of the edge is completely positioned within the bore so as to be reinforced by the bore wall.
