Abstract (en)
[origin: US2010288564A1] A cutting element for use in a drill bit for drilling subterranean formations including a substrate having a body including an upper surface extending transversely to a longitudinal axis of the body, a superabrasive layer overlying the upper surface of the substrate, wherein the superabrasive layer includes an annular shape having a central opening defined by an inner surface. The cutting element further includes an abrasive insert overlying the upper surface of the substrate and disposed within the central opening of the superabrasive layer, wherein the abrasive insert has an upper surface having a surface roughness (Ra) of greater than about 1 micron.
