PDC (Polycrystalline diamond compact) rock cutter blanks consist of a layer of polycrystalline
diamond integrally sintered to a tungsten carbide substrate using a high temperature,
ultra-high pressure process, which has high abrasion resistance and impact resistance.
SuperAbrasive Techniques Ltd’s PDC is designed for oil-well and mining bits, which
are suitable for use in soft to medium hard rock formations.
