Abstract

An abrasive compact is made by a method comprising the steps of providing a circular cylindrical substrate having an upper with a non-circular recess therein defined by non-intersecting side walls. The recess is filled with diamond grains and is positioned in a press. The substrate and diamond grains are subjected to high temperature and pressure conditions in the press to sinter the diamond grains and bond the sintered diamond grains to the substrate in the form of a non-circular diamond layer. The portions of the substrate not covered by the diamond layer are removed.
