Abstract

A method for forming a cutting element that includes forming at least one cavity in at least one surface of a polycrystalline abrasive body; placing the polycrystalline abrasive body adjacent a substrate such that an opening of at least one cavity is adjacent the substrate at an interface, wherein an interface surface of the substrate is non-mating with the polycrystalline abrasive body; and subjecting the polycrystalline abrasive body and substrate to high pressure /high temperature conditions is disclosed.
