3M 7010308995 Cubitron Ii 987C Fiber Disc 80 Grit 4.5 in

Product Description

The 3M 7010308995 is a Cubitron II 987C coated fiber disc engineered for medium to heavy-duty metal grinding, weld grinding, and beveling applications. It uses 3M Precision-Shaped Grain, a triangular ceramic abrasive that maintains sharp cutting points longer than conventional minerals. The result is a higher cut rate, less required grinding pressure, and significantly extended disc life compared to standard fiber discs. At 4.5 inches in diameter with an 80-grit rating, this disc is built for aggressive stock removal on steel, stainless steel, and heat-sensitive alloys. A stiff fiber backing and strong resin bond add structural rigidity and tear resistance under sustained load.

This disc is suited for fabrication shops, weld prep and finishing operations, pipe beveling, and robotic or pressure-assisted grinding systems. The integrated grinding aid helps manage heat buildup, making it a practical choice when working with heat-sensitive alloys where discoloration or metallurgical damage is a concern. It is sold individually (each) with a minimum order quantity of 100 units, making it appropriate for production and fleet-level purchasing.

Key Features

• 3M Precision-Shaped Grain holds sharp cutting points longer, delivering faster cuts at lower pressure
• Integrated grinding aid reduces disc surface temperature during use, protecting heat-sensitive alloys
• Stiff fiber backing and strong resin bond resist tearing under high-pressure and robotic grinding loads
• Longer disc life means fewer changeouts and less downtime in production environments
• 80-grit rating targets aggressive stock removal and weld grinding

Compatibility

Designed for use on standard 4.5-inch angle grinders with a compatible fibre disc backing pad. Suitable for grinding and finishing on steel, stainless steel, and heat-sensitive alloys in fabrication and weld applications.

Installation Notes

Installation and disc changes should be performed by qualified personnel following the grinder manufacturer's instructions and applicable ANSI B11 safety standards. Power down and disconnect the grinder before mounting or removing the disc. Inspect the backing pad for wear or damage before each disc installation. Never exceed the maximum RPM rating marked on the disc.
