  • Contoured PCD and PCBN segments for cutting tools containing such segments
    Patent number: 9468980
    Abstract: Contoured helical solid polycrystalline PCD and PCBN superabrasive segments are provided for attachment to cutting tool substrates such as twist drill tips, reamers, burrs and endmills. Segments are provided in near to net shape for attachment to a tool substrate thereby requiring reduced finishing steps and providing increased tailorability of grade and quality of final polycrystalline segments. Cutting tools comprising cutting tool substrates having attached thereto a contoured helical solid polycrystalline PCD and PCBN superabrasive segments are also disclosed.
