3M Precision Shaped Grain maintains super-sharp points, cuts 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
