Patent ID: 7048081

Claim:
A cutting element for use on a rotary drill bit for drilling subterranean formations, the cutting element comprising: a supporting substrate; a superabrasive table including a cutting face having a cutting edge along a periphery thereof and consisting essentially of a plurality of mutually superabrasively bonded individual superabrasive particles comprising: a first volume of individual superabrasive particles, wherein the individual superabrasive particles of the first volume generally exhibit a wear rate within a first wear rate distribution range; and at least a second volume of individual superabrasive particles interspersed with superabrasive particles of the first volume, wherein the individual superabrasive particles of the at least a second volume generally exhibit a wear rate within a second wear rate distribution range different than the first wear rate distribution range; wherein the cutting edge of the cutting face, upon contact with a subterranean formation, wears in a nonuniform manner so as to exhibit an asperital profile.
