3M Precision Shaped Grain maintains super-sharp points that cut exceptionally fast with less pressure Disc life is significantly longer, completing more parts per disc and requiring fewer disc changes Triangular shaped ceramic grain lasts up to two times longer than other ceramic abrasives—it wears evenly, runs cool, and optimizes mineral breakdown Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding and beveling Durable and tear resistant with a stiff fibre backing and strong resin bond for high pressure weld grinding and bevelling Minimise operator fatigue with 3M Precision Shaped Grain reducing grinding pressure
