3M 051141-27664 Cubitron II Fibre Disc TN Quick Change Grit - 987C 4.5 80+

The 3M Cubitron II Fibre Disc 987C delivers exceptional performance for medium to heavy-duty metalworking operations. Featuring 3M Precision-Shaped Grain technology, this 4.5-inch disc achieves a higher cut-rate, greater durability, and longer life than conventional fiber discs—all while requiring less grinding pressure from the operator.

Key Features:

• 3M Precision-Shaped Grain maintains super-sharp triangular points that slice cleanly through metal for exceptionally fast cutting
• Built-in Tinnerman Nut (TN) quick change attachment allows for easy, tool-free screw-on disc changes
• Grinding aid incorporated into the disc minimizes grinding temperatures, protecting heat-sensitive alloys from heat damage and discoloration
• 80+ grit provides fine finishing ideal for grinding smaller welds, blending, and deburring applications
• Stiff fiber backing with strong resin bond ensures durability and tear-resistance for high-pressure weld grinding and beveling
• Self-fracturing mineral continuously sharpens itself, running cooler and lasting significantly longer than conventional ceramic abrasives
• Optimized for all metals including stainless steel, carbon steel, and heat-sensitive alloys

Ideal for robotic weld grinding, pressure-assisted grinding operations, weld blending, deburring, and metal finishing applications. The 987C series incorporates a special grinding aid that keeps the workpiece cooler, making it particularly well-suited for stainless steel and other heat-sensitive materials where heat damage and re-work must be minimized.
