Self sharpening polycrystalline diamond compact with high impact resistance

Image Number 2 for United States Patent #7070635.

A polycrystalline diamond compact for use in cutting operations with a renewable sharp cutting edge, high abrasion resistance and high impact strength. The polycrystalline diamond is a composite composed of a matrix of coarse diamond interspersed with large agglomerated particles of ultra fine diamond. The agglomerated particles produce sharp cutting edges that are protected from impact forces by the overall uniform matrix of coarse diamond crystals. The self-sharpening cutter is highly resistant to spalling and catastrophic fracture.
