Abstract:
A cutting element and a method of making the superabrasive cutter are disclosed. The cutting element has a substrate and a superabrasive layer. The substrate has an inner face and an annular face. The inner face may have a center. The annular face may have a periphery. A superabrasive layer attaches to the substrate along the inner face and the annular face, wherein the inner face slopes outwardly and upwardly from the center at an angle ranging from between about 1° and about 7° from horizontal.
