Abstract
A cutting element may be formed by sintering together a plurality of metal carbide grains and a metal binder to form a substrate, forming at least one binder gradient in the substrate, and mounting an abrasive layer to the substrate at an interface. The concentration of metal binder material may decrease along at least one direction to form the at least one binder gradient.
