PDC cutter

1608mm pdc drill cutter for Coal Ming, PDC cutters have helped change the exploration bit industry. PDC bits are now over 50% of the bit , and are still growing.

 PDC cutters for oil&gas bits is produced by using the higher degree of diamond powder and tungsten carbide substrate. Microstructure with complete C-C bond combination is characterized between the diamond grains in polycrystalline diamond layer, which allows the high strength, hardness and wearing property of diamond layer. We adopt many types structure of the interface between diamond layer and carbide , and use the special technological post-processing in order to effectively reduce residual stress of PDC while make the interface combination firmer and more symmetrical. So PDC cutter displays satisfying thermal stability, higher impact resistance and excellent performance.
