3M Fiber Disc 987C 7" x 7/8" Precision Shaped Ceramic Grain 36+ Grit

Precision-Shaped Grain maintains super-sharp points that cut exceptionally fast with less pressure. Mineral runs cooler and disc life is significantly longer, completing more parts per disc and requiring fewer disc changes. Reduces changeouts and downtime in robotic and pressure-assisted applications. Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding or beveling. Grinding aid incorporated on the disc minimizes grinding temperatures for heat-sensitive alloys.
