SUPREME Polycrystalline Diamond CompositesTM (SUPREME PDCTM) rock cutting blanks consist of a polycrystalline diamond layer sintered with tungsten carbide substrate under ultra-high pressure and ultra-high temperature. SUPREME PDCTM are produced with carefully chosen high-quality industrial diamond and tungsten carbide materials as well as advanced synthesizing technology. Combining the strengths of both diamond and tungsten carbide, SUPREME PDCTM possesses extremely high abrasion resistance and extremely strong impact resistance ability. Versatile in applications, SUPREME PDCTM is widely used for various drilling tools such as petroleum bits, mining bits, geological drilling bits, and other rock cutting and processing tools.
