Patent ID: 8162082

Claim:
A superabrasive compact, comprising: a cemented carbide substrate including a first interfacial surface having a first recess formed therein, and a second interfacial surface spaced from the first interfacial surface and having a second recess formed therein; a first superabrasive cutting portion bonded to the first interfacial surface of the cemented carbide substrate and disposed in the first recess, the first superabrasive cutting portion including a first working surface, at least one first lateral surface, and a first cutting edge that generally defines part of a circle, wherein at least a portion of the at least one first lateral surface is bonded to the cemented carbide substrate; and a second superabrasive cutting portion bonded to the second interfacial surface of the cemented carbide substrate and disposed in the second recess, the second superabrasive cutting portion spaced from the first superabrasive cutting portion by the cemented carbide substrate, the second superabrasive cutting portion including a second working surface generally opposing the first working surface of the first superabrasive cutting portion, at least one second lateral surface, and a second cutting edge that generally defines part of a circle, wherein at least a portion of the at least one second lateral surface is bonded to the cemented carbide substrate.
