machine-building industry, creation of materials for polishing various surfaces, e. g. metals and alloys, and also materials of mineral origin. SUBSTANCE: described is new composite polymeric material for abrasive tools based on polytetrafluoroethylene and natural diamond powder. Material comprises fluorex 1510 prepared from oil refining waste and beta-sialon, ratios of ingredients being as follows, wt %: natural diamond powder, 40; fluorex, 3-5; beta-sialon, 2; and polytetrafluoroethylene, the balance. Claimed material makes it possible to increase wear resistance and service life of diamond abrasive tools due to addition of fillers to increase cutting properties due to addition of natural diamond powders. EFFECT: improved properties of the abrasive tools. 1 tbl
