PDC Cutters and Tungsten Carbide Substrates for High-Performance Drilling

Polycrystalline diamond compact (PDC) cutters consist of a tungsten carbide substrate and a polycrystalline diamond (PCD) layer. Sanwu offers both complete PDC cutters and separate tungsten carbide substrates for oil & gas drill bits, coal mining bits, and other demanding applications.

Why choose Sanwu PDC cutters and carbide substrates?

We utilize the finest tungsten carbide powders in China (GESAC) and high-quality PCD sheets, combined with our unique brazing techniques—enabling exceptional resistance to wear and impact, superior thermal stability, and a high rate of penetration (ROP).
