3M 7010326433 Cubitron Ii 987C Fiber Disc 36 Grit 5 in

Product Description

The 3M 7010326433 is the Cubitron II 987C coated fiber disc, a high-performance abrasive disc engineered for medium to heavy-duty grinding, weld grinding, and beveling applications. Built around 3M Precision-Shaped Grain, this 5-inch disc delivers a fast cut rate and extended disc life while requiring less grinding pressure than conventional fiber discs. The stiff fiber backing and strong resin bond hold up under aggressive use, including robotic and pressure-assisted grinding setups. A built-in grinding aid helps manage heat buildup, making this disc suitable for heat-sensitive alloys. Fabricators, welders, and metal finishing tradespeople are the primary users.

This disc is sized at 5 inches in diameter with a 36-grit abrasive rating and a maximum operating speed of 12,000 RPM. It is well-suited for industrial and production environments where disc longevity and consistent cut rate directly affect throughput. Typical applications include weld seam removal, surface preparation, and edge beveling on steel, stainless steel, and other ferrous metals. The disc is sold individually (each) with a minimum order quantity of 100 units, making it appropriate for production shops and fleet-level supply purchasing.

Key Features

• 3M Precision-Shaped Grain maintains sharp cutting points for fast stock removal with reduced grinding pressure
• Longer disc life means more parts per disc and fewer changeouts compared to conventional fiber discs
• Stiff fiber backing and strong resin bond provide tear resistance for high-pressure weld grinding and beveling
• Integrated grinding aid reduces surface temperatures, protecting heat-sensitive alloys during grinding
• Rated to 12,000 RPM, compatible with standard right-angle grinder speeds
• Reduces downtime in robotic and pressure-assisted grinding applications

Compatibility

Designed for use with standard 5-inch right-angle grinders and disc grinders capable of accepting Type 27 or Type 29 fiber disc configurations. No specific model compatibility was provided in the product data.

Installation Notes

Fiber discs of this type are installed and serviced by fabricators, welders, and grinding equipment operators following standard abrasive safety practices. Always inspect the disc for damage before mounting and ensure the grinder backing pad is rated for the disc diameter. Never exceed the maximum operating speed of 12,000 RPM. Wear appropriate personal protective equipment including face shield, gloves, and hearing protection during operation.
