PCD coal mining drill bits

RJ Polycrystalline Diamond Composites (RJ PDC) consist of a polycrystalline diamond layer sintered with tungsten carbide substrate under extremely high pressure and high temperature. RJ 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, so they are widely used for various drilling tools such as petroleum bits, mining bits, geological drilling bits, and other rock cutting and processing tools.

RJ mining PDC cutters have earned a good reputation by offering the best combination of cost and performance.

RJ mining PDC cutters are used for regular and enhanced anchor shank drill bits, PDC core bits, and full-hole bits. We supply different PDC cutter grades which are suitable for soft, soft-medium, medium hard, hard and tough formations.

Note: The standard shape of RJ PDC is round; other shapes, such as rectangle, triangle, square, semi-circle and so on, can also be custom-made per customers’ requirements.
