3M 7010362308 Cubitron Ii 987C Fiber Disc 7 in 80 Grit

Product Description

The 3M 7010362308 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 on a stiff fiber backing with a strong resin bond, the disc uses 3M Precision-Shaped Grain to maintain sharp cutting points throughout its service life. At 7 inches in diameter and 80 grit, it is rated to 8600 RPM. The incorporated grinding aid reduces heat buildup, making this disc suitable for heat-sensitive alloys. Metal fabricators, welders, and angle-grinder operators in production and fabrication shops install this disc.

The 987C fiber disc is used in production grinding environments where cut rate, disc longevity, and reduced downtime matter. It handles high-pressure weld grinding, surface prep, and beveling on steel and alloy workpieces. The stiff fiber backing resists tearing under load, and the disc is compatible with robotic and pressure-assisted grinding setups where consistent performance across a full disc life reduces changeout frequency. It is sold individually.

Key Features

• 3M Precision-Shaped Grain maintains sharp cutting points for fast stock removal with less applied pressure
• Stiff fiber backing and strong resin bond provide tear resistance in high-pressure weld grinding and beveling
• Grinding aid incorporated into the disc face reduces grinding temperatures on heat-sensitive alloys
• Higher cut rate and longer disc life reduce changeout frequency in robotic and pressure-assisted applications
• 80 grit designation suits medium to heavy material removal and weld blending

Compatibility

Designed for use with standard 7-inch angle grinders and disc grinders in metal fabrication, weld grinding, and surface preparation applications. Suitable for robotic and pressure-assisted grinding setups.

Installation Notes

Install and replace abrasive discs with the grinder unplugged or the power source locked out per applicable safety standards. Verify the grinder spindle speed does not exceed the disc maximum rating of 8600 RPM before mounting. Inspect the disc for cracks or damage before each use and do not use a damaged disc. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation.
