Patent ID: 8172011

Claim:
A method of manufacturing a tool component including a layer of ultra-hard abrasive material bonded to a substrate, the layer of ultra-hard abrasive material including a pair of opposed end surfaces, an upper surface defined between the end surfaces, and at least one curved and tapered cutting edge defined at the intersection of the respective end surfaces and the upper surface, the method comprising: providing a body including the layer of ultra-hard abrasive material bonded to the substrate along an interface which is transverse to a longitudinal axis of the body; cutting a blank from the body transverse to a longitudinal axis of the body and through an interface between the layer of ultra-hard abrasive material and the substrate, the blank having a generally cylindrical shape and comprising a layer of ultra-hard abrasive material bonded lengthwise to a substrate layer; and shaping the blank into a desired shape for the tool component.
