FIELD: process engineering.
SUBSTANCE: invention relates to grinding and may be used for machining, milling, drilling etc. Abrasive tool comprises super hard polycrystalline composite material (SPCM) and binder phase. SPCM consists of super hard abrasive material particles with multimodal size distribution and general mean particle size of smaller than 12 mcm and higher than 2 mcm. SPCM has multiple pores while binder phase is distributed in said pores to form separate cavities filled with binder. Quantity of said filled cavities makes over 0.45 cavity per square mcm.
EFFECT: higher impact resistance, fatigue strength and wear resistance.
