3M – 4” Cubitron II Fiber Disc Grit 80 – 981CP

3M™ Fibre Disc 981CP is engineered with 3M Precision-Shaped Grain to deliver fast, consistent cutting and extended disc life. Designed to handle tough grinding jobs, it outperforms conventional abrasives by maintaining sharp cutting edges and reducing heat buildup throughout use.

This advanced grain technology allows each triangular-shaped grain to continuously fracture, forming new sharp edges that slice cleanly through metal. The result is longer-lasting performance, improved efficiency, and cooler operation under high-pressure grinding.

Key Features

• Precision-Shaped Grain for fast, efficient cutting
