Abstract
Embodiments of the invention relate to superabrasive compacts including multiple superabrasive cutting portions and methods of fabricating such superabrasive compacts. In an embodiment, a superabrasive compact comprises a cemented carbide substrate including a first interfacial surface and a second interfacial surface longitudinally spaced from the first interfacial surface. A first superabrasive cutting portion may be bonded to the first interfacial surface of the cemented carbide substrate. The first superabrasive cutting portion includes a first working surface. A second superabrasive cutting portion may be bonded to the second interfacial surface of the cemented carbide substrate and spaced from the first superabrasive cutting portion. The second superabrasive cutting portion includes a second working surface that generally opposes the first working surface of the first superabrasive cutting portion.
