Based on HP-HT sintering of diamond powders of two dispersion levels with activating additive the polycrystalline composite diamond - tungsten carbide has been created. It combines high hardness, fracture toughness and thermal stability.This is achieved through the formation of tungsten carbide nanoparticles chemically bound to the diamond between the diamond particles. Laboratory tests on drilling tools equipped with working elements of the composite were performed. They showed the feasibility of its use in drilling anchor holes in rocks up to 168 MPa strength and abrasiveness up to 45 mg.
