3M Precision Shaped Grain maintains super-sharp points that cut exceptionally fast with less pressureDisc life is significantly longer, completing more parts per disc and requiring fewer disc changesTriangular shaped ceramic grain lasts up to two times longer than other ceramic abrasives—it wears evenly, runs cool, and optimizes mineral breakdownStiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding and bevelingStiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding and beveling
