Polycrystalline diamond compact (PDC) cutters were manufactured using diamond powders and tungsten carbide under high pressure and high temperature (HPHT). The PDC cutters show exceptionally high abrasion resistance and high impact resistance, which have been widely used in the oil/gas drilling, geological exploration, coal mining applications, and cutting tools for metal machining.
JINDI can provide PDC cutters from 13 mm to 19 mm in diameter, which can also be customized based on customer requirement.
