3M 051115-66780 Cubitron II Roloc Fibre Disc 982C 4 Inch 36+ Grit

The 3M Cubitron II Roloc Fibre Disc 982C uses Precision-Shaped Grain technology to deliver up to twice the cut-rate, durability, and life of conventional fiber discs when grinding carbon steel—all with less grinding pressure required by the operator. This 4-inch diameter disc features a 36+ extra coarse grit rating and utilizes a Type TR quick-change Roloc attachment system for fast, tool-free disc changes between grades or applications.

Key Features:

• 3M Precision Shaped Grain maintains super sharp points that cut exceptionally fast with less pressure
• Triangular shaped ceramic grains are electrostatically oriented on the backing to form sharp peaks that act like individual cutting tools, continuously fracturing into new sharp cutting edges
• PSG runs cooler, reducing metal discoloration/oxidation and the chance of heat related stress cracks
• Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high pressure weld grinding
• Maximum speed rating of 12,000 RPM
• Disc life is significantly longer, completing more parts per disc and requiring fewer disc changes

The 36+ grit rating makes this disc ideal for beveling and grinding large welds, providing maximum stock removal and a coarse finish. Suitable for all metals with optimized performance on carbon steel. The Roloc attachment system provides for easy disc changes between grades or applications.
