3M 7010363648 Cubitron Ii 982C Fiber Disc 36 Grit 7 in

Product Description

The 3M 7010363648 is the Cubitron II 982C coated fiber disc, a 7-inch, 36-grit abrasive disc designed for aggressive material removal on carbon steel and similar metals. It uses 3M Precision-Shaped Grain, a triangular ceramic mineral that maintains sharp cutting points longer than conventional ceramic abrasives. The result is up to twice the cut rate and disc life compared to standard fiber discs, with less grinding pressure required from the operator. Rated at 8,600 RPM, this disc is built for manual, robotic, and pressure-assisted angle grinder applications where throughput and disc longevity matter.

This disc is suited for medium to high-pressure grinding tasks including weld grinding, beveling, and surface preparation on carbon steel. It is commonly used in fabrication shops, structural steel work, and pipeline applications where operators need consistent cut performance across a full disc life. Fewer disc changes mean less downtime and lower total cost per part. The stiff fiber backing and strong resin bond hold up under heavy lateral and plunge loads typical of production grinding environments.

Key Features

• 3M Precision-Shaped Grain holds sharp cutting points longer, delivering fast stock removal with less applied pressure
• Triangular ceramic grain wears evenly and runs cooler than conventional ceramic abrasives, extending disc life up to two times
• Stiff fiber backing and strong resin bond resist tearing under high-pressure weld grinding and beveling loads
• Compatible with manual, robotic, and pressure-assisted grinding setups, reducing changeout frequency in all three environments
• Reduced grinding pressure lowers operator fatigue during extended production runs
• 36-grit designation targets aggressive material removal and weld leveling rather than finish grinding

Compatibility

Designed for use on 7-inch angle grinders and disc grinders rated at or above 8,600 RPM, primarily for grinding and beveling carbon steel in fabrication and industrial maintenance applications.

Installation Notes

Always verify the grinder's rated RPM meets or exceeds the disc's 8,600 RPM maximum before mounting. Power down and disconnect the grinder before changing discs, and inspect the backing pad for wear or damage prior to installation. Wear appropriate PPE including a face shield and grinding gloves. Follow all applicable ANSI B7.1 and OSHA standards for abrasive wheel use.
