3M 7010362281 Cubitron Ii 987C Fibre Disc 80 Grit 4.5 in

Product Description

The 3M 7010362281 is the Cubitron II 987C coated fibre disc, a high-performance abrasive engineered for medium to heavy-duty grinding, weld grinding, and beveling operations. Built around 3M Precision-Shaped Grain technology, this disc cuts faster and at lower pressure than conventional abrasive discs. The stiff fiber backing and strong resin bond deliver tear-resistance under aggressive load. A built-in grinding aid helps manage heat at the workpiece surface, making it well-suited for heat-sensitive alloys. At 4.5 inches in diameter and 80 grit, it fits standard angle grinders and is sized for production-volume metalworking environments.

This disc is designed for production and fabrication shops performing weld grinding, surface preparation, deburring, and beveling on steel and heat-sensitive alloys. It is also engineered to perform in robotic and pressure-assisted grinding applications where consistent cut rate and extended disc life reduce changeover frequency and machine downtime. Each disc is sold individually, with a minimum order quantity of 100 units, making it appropriate for high-volume shop stock.

Key Features

• 3M Precision-Shaped Grain maintains sharp cutting points for fast stock removal at reduced grinding pressure
• Stiff fiber backing and strong resin bond resist tearing under high-pressure weld grinding and beveling loads
• Built-in grinding aid reduces heat buildup, protecting heat-sensitive alloys during grinding
• Extended disc life completes more parts per disc and reduces changeover frequency compared to conventional fiber discs
• Suited for robotic and pressure-assisted applications where consistent performance across a disc lifecycle is critical

Compatibility

Designed as a coated abrasive fibre disc for use with standard angle grinders accepting 4.5-inch diameter discs in medium to heavy-duty metal fabrication and weld grinding applications.

Installation Notes

Installation of abrasive fibre discs should be performed by qualified personnel following the grinder manufacturer's guard and speed rating requirements. Verify that the grinder's rated RPM meets or does not exceed the disc's maximum RPM before mounting. Power down and disconnect the grinder from its power source before changing discs. Always wear appropriate PPE including face shield, gloves, and hearing protection during operation.
