3M 7010308171 Cubitron Ii 987C Fiber Disc 60 Grit 7 Inch

Product Description

The 3M 7010308171 is a coated fiber disc in the Cubitron II 987C series, engineered for medium to heavy-duty material removal on metal fabrication applications. It uses 3M Precision-Shaped Grain, a triangular ceramic abrasive that maintains sharp cutting points throughout the disc's life, delivering a higher cut rate with less applied pressure than conventional abrasive fiber discs. The stiff fiber backing and strong resin bond system hold up under high-pressure grinding, weld grinding, and beveling operations. A built-in grinding aid helps manage heat buildup, making this disc suitable for heat-sensitive alloys. Metalworkers, fabricators, and weld technicians are the primary installers and operators.

This disc is suited for angle grinder applications in production, fabrication shop, and robotic grinding environments where consistent cut rate and extended disc life reduce changeouts and downtime. The 7-inch diameter and 60-grit designation position it for aggressive stock removal and weld blending on ferrous and non-ferrous metals. Its design supports both manual and pressure-assisted grinding setups, including automated robotic systems that require predictable abrasive wear performance across high-volume part runs.

Key Features

• Precision-Shaped Grain maintains sharp cutting points for fast material removal with lower applied pressure
• Stiff fiber backing and strong resin bond provide tear resistance in high-pressure weld grinding and beveling
• Integrated grinding aid reduces disc surface temperature, protecting heat-sensitive alloys during grinding
• Extended disc life means fewer changeouts per shift in both manual and robotic applications
• 60 grit provides aggressive stock removal suitable for weld grinding and surface prep
• Rated to 8600 RPM for use with standard 7-inch angle grinders

Compatibility

Designed for use with 7-inch angle grinders rated at or above 8600 RPM, in manual, pressure-assisted, and robotic grinding configurations on ferrous and non-ferrous metals.

Installation Notes

This disc is installed and operated by metalworkers, fabricators, and grinding technicians. Before mounting, confirm the grinder is rated for the disc diameter and RPM. Always inspect the disc for damage before use and never exceed the maximum RPM rating. Wear appropriate PPE including face shield and gloves during all grinding operations.
