3M Cubitron II Fibre Disc 982C - 80+ Grit Metal Grinding Disc - Ceramic Precision Shaped Grain - For Angle Grinders - 4.5" x 7/8" Center Hole

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

Reduces changeouts and downtime in robotic and pressure-assisted applications

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
