Supreme PDC (Polycrystalline Diamond Compact) rock cutter blanks consist of polycrystalline diamond layer sintered with tungsten carbide substrate under ultra-high temperature and ultra-high pressure. Combining the strengths of both diamond and tungsten carbide, the process renders to the products a combined quality of extremely high abrasion resistance and extremely strong impact resistance ability
　Supreme PDC is specially designed for various drilling tools such as petroleum bits, mining bits, and other geological drilling bits, suitable for use in soft to medium hard rock formations .
