Polycrystalline Diamond Composites (PDC) rock cutting blanks consist of a polycrystalline diamond layer sintered with tungsten carbide substrate under ultra-high pressure and ultra-high temperature. PDC 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,  PDC possesses extremely high abrasion resistance and extremely strong impact resistance ability. Versatile in applications, SUPREME PDC is widely used for various drilling tools such as petroleum bits, mining bits, geological drilling bits, and other rock cutting and processing tools.

1. SSI Series: Flat interface PDC, suitable for drilling bits for low and medium hard rock formations.

2. SSII Series: Flat and non-planar interface PDC, with high level of hardness and abrasion resistance ability, suitable for oil and geological drilling bits, rock cutting bits, and stone processing tools.

The standard shape of  PDC is round; Othershapes, such as rectangle, triangle, square, semi-circle and so on, can also be custom-made per customers' requirements.
