4 in Dia, 400FF, Precision Shaped Ceramic, 60+ Grit

3M Cubitron II Fibre Disc 982C uses 3M Precision-Shaped Grain to generate up to twice the cut-rate, durability, and life of other fiber discs when grinding carbon steel - all with less grinding pressure required by the operator. That means less operator fatigue, faster throughput, and more parts per disc when tackling medium and high-pressure grinding applications.

• 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 manual, robotic and pressure-assisted applications
• Triangular shaped ceramic grain lasts up to two times longer than other ceramic abrasivesit wears evenly, runs cool, and optimizes mineral breakdown
