3M 7010362226 Cubitron Ii 987C Fiber Disc 80 Grit 5 in

Product Description

The 3M 7010362226 is the Cubitron II 987C coated fiber disc, a 5-inch abrasive disc designed for medium to heavy-duty grinding, weld grinding, and beveling applications on metal. Built around 3M Precision-Shaped Grain technology, this disc delivers a higher cut rate and longer service life compared to conventional fiber discs while requiring less applied pressure. The stiff fiber backing and strong resin bond hold up under aggressive use. A built-in grinding aid helps keep surface temperatures down, making this disc suitable for heat-sensitive alloys and high-pressure operations. It is rated to 12000 RPM.

This disc is used in fabrication shops, weld grinding stations, metal prep operations, and robotic or pressure-assisted grinding setups. The 80-grit specification makes it well suited for aggressive stock removal and weld seam blending on steel, stainless, and similar alloys. It is installed on standard 5-inch angle grinders and disc grinders by metalworkers, fabricators, and maintenance technicians who require consistent cut performance across high-volume part runs.

Key Features

• 3M Precision-Shaped Grain maintains sharp cutting points for fast stock removal with reduced pressure
• Stiff fiber backing and strong resin bond provide tear resistance in heavy-duty weld grinding and beveling
• Built-in grinding aid reduces heat buildup, protecting heat-sensitive alloys during extended grinding
• Longer disc life and fewer changeouts reduce downtime in robotic and pressure-assisted applications
• Rated to 12000 RPM for compatibility with standard high-speed angle grinders
• 80 grit for aggressive material removal and weld seam blending

Compatibility

Designed for use on standard 5-inch angle grinders and disc grinders accepting 5-inch fiber discs with appropriate backing pads.

Installation Notes

This disc is installed by qualified metalworkers and fabricators using a compatible 5-inch backing pad on an angle grinder. Verify the grinder RPM rating meets or exceeds the disc rating before mounting. Inspect the disc for damage before each use and discard any cracked or torn discs. Always use appropriate PPE including face shield and grinding gloves when operating.
