3M 7100099299 Coated Fibre Disc 60 Grit 7 Inch

Product Description

The 3M 7100099299 is a coated fibre disc engineered for high-speed material removal on carbon steel. Built around 3M Precision Shaped Grain ceramic abrasive, it delivers faster cut rates and longer service life than conventional fibre discs. The stiff fibre backing and strong resin bond provide tear resistance under heavy grinding loads. At 7 inches in diameter with a 60-grit rating, this disc is suited for demanding metal fabrication tasks including weld removal, beveling, edge chamfering, and surface blending. Licensed tradespeople and fabricators working in industrial and commercial settings will find it a reliable production-grade abrasive tool.

The 782C disc is designed for use in heavy-duty metalworking applications on carbon steel. Typical use cases include weld grinding, blending, and finish refinement on structural and fabricated components. The disc mounts to angle grinders using compatible 3M disc pad face plates and hubs, which are sold separately. It is equally applicable in fabrication shop environments and field repair scenarios where rapid stock removal is required.

Key Features

• Precision Shaped Grain ceramic abrasive delivers higher cut rates than conventional abrasive minerals
• 60-grit rating suited for aggressive stock removal, weld grinding, and beveling
• Stiff fibre backing resists tearing under heavy grinding loads
• Strong resin bond maintains abrasive integrity throughout extended use cycles
• Compatible with 3M disc pad face plates and hubs (sold separately)
• Long-lasting construction helps lower cost per part compared to standard fibre discs

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on carbon steel in grinding and blending applications requiring a 7-inch coated fibre disc.

Installation Notes

Installation is performed by metal fabricators or maintenance trades using a right-angle grinder fitted with an appropriate 3M disc pad and hub. Power down and disconnect the grinder from its power source before mounting or removing the disc. Inspect the disc for damage before each use and never operate above the maximum RPM rating marked on the disc or tool. Follow applicable ANSI B11 and OSHA 1910.215 grinding safety requirements.
