FIELD: making abrasive tools. SUBSTANCE: diamond particles is covered with carbide-forming metal and binding material containing a volatile solvent. The process is accompanied with heat treating to provide dilution of carbide-forming metal. The diamond particle granule obtained is provided with carbide-forming metal coating interposed between the diamond particle and layer of metallic powder. The caking temperature of the metallic powder is less by at least 50°C than the melting temperature of the carbide- forming metal. The granules are 0.2- 2.4 mm in size. EFFECT: enhanced efficiency. cl, dwg
