3M 7010363673 Cubitron Ii 987C Fiber Disc 5 in 60 Grit

Product Description

The 3M 7010363673 is a Cubitron II 987C coated fiber disc engineered for medium to heavy-duty grinding, weld grinding, and beveling on metal fabrication lines. It combines 3M Precision-Shaped Grain with a stiff fiber backing and a strong resin bond to deliver a high cut rate, extended disc life, and consistent performance under heavy load. Rated at 12000 RPM and sized at 5 inches in diameter with a 60-grit abrasive, this disc is built for use with right-angle grinders in professional metalworking and fabrication environments. A built-in grinding aid helps manage heat buildup, making it suitable for heat-sensitive alloys.

This disc is used in industrial and trade fabrication settings where high stock removal and durability are required. Typical applications include weld grinding, seam removal, and edge beveling on structural steel, stainless steel, and other metals. It is well suited for both manual grinding and pressure-assisted or robotic grinding systems. Metalworkers, fabricators, and pipefitters working in heavy manufacturing or field structural applications are the primary installers and users of this disc.

Key Features

• 3M Precision-Shaped Grain maintains sharp cutting points for fast material removal with reduced grinding pressure
• Stiff fiber backing and strong resin bond provide tear resistance in high-pressure weld grinding and beveling operations
• Built-in grinding aid minimizes disc and workpiece temperatures, protecting heat-sensitive alloys
• Extended disc life reduces changeouts and downtime in robotic and pressure-assisted grinding applications
• 60-grit abrasive suits medium to heavy stock removal tasks on ferrous and non-ferrous metals

Compatibility

Designed for use with standard right-angle grinders and pressure-assisted or robotic grinding systems that accept 5-inch fiber discs with a matching arbor configuration. Confirm grinder RPM rating meets or exceeds the 12000 RPM disc rating before use.

Installation Notes

Mounting and disc changes should be performed by qualified operators following the grinder and disc manufacturer safety guidelines. Always confirm the grinder is powered off and the wheel has come to a complete stop before changing discs. Inspect the disc for cracks, tears, or damage before each use and do not use a damaged disc. Eye protection, face shield, and appropriate PPE are required during operation.
