Abstract
A polycrystalline diamond cutting element is shown which includes a mounting body having a leading face and a trailing face and a thin layer of super hard material carried on the leading face of the mounting body which defines a cutting face. The cutting face has a circular outer periphery which is interrupted to form a recess in the cutting face which continues through the mounting body. The recess mates in complementary fashion with the outer periphery of a second cutting element when the cutting elements are arranged side-by-side with the cutting faces thereof in a common plane.
