3M 7010308152 Cubitron Ii 987C Fibre Disc 4 Inch 60 Grit

Product Description

The 3M 7010308152 is the Cubitron II 987C coated fibre disc, a precision abrasive disc engineered for medium to heavy-duty grinding, weld grinding, and beveling applications. Built around 3M Precision-Shaped Grain on a stiff fiber backing with a strong resin bond, this disc delivers a higher cut rate and longer service life compared to conventional fibre discs. At 4 inches in diameter and 60 grit, it operates at up to 15000 rpm and is suited for fabrication environments where throughput and disc longevity directly affect labor costs. A built-in grinding aid reduces heat buildup, making it appropriate for heat-sensitive alloys and high-pressure applications.

This disc is used in metal fabrication shops, structural steel work, and manufacturing environments requiring aggressive material removal with controlled heat. It fits standard angle grinders and pressure-assisted or robotic grinding systems. The 60 grit rating targets weld seam removal, surface conditioning, and edge beveling on steel and similar ferrous metals. Technicians and fabricators handling high-volume grinding operations benefit from fewer disc changes and reduced downtime during extended production runs.

Key Features

• 3M Precision-Shaped Grain holds sharp cutting points longer, delivering fast cut with lower grinding pressure
• Stiff fiber backing and strong resin bond resist tearing under high-pressure weld grinding and beveling loads
• Integrated grinding aid minimizes disc and workpiece temperatures, protecting heat-sensitive alloys
• Extended disc life reduces changeouts and downtime in robotic and pressure-assisted applications
• Rated to 15000 rpm for use with standard right-angle grinders

Compatibility

Designed for use on standard 4 inch angle grinders and pressure-assisted or robotic grinding systems that accept fibre discs with a compatible arbor size.

Installation Notes

Disc mounting and replacement should be performed by qualified personnel following the grinder manufacturer's instructions and applicable ANSI B11 or OSHA abrasive wheel safety standards. Always power down and disconnect or lock out the grinder before changing discs. Inspect the disc for cracks or damage before each use and never exceed the rated maximum speed of 15000 rpm. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation.
