3M 7100099219 Ceramic Fibre Disc 7 Inch 80 Grit

Product Description

The 3M 7100099219 is a 7-inch coated fibre disc engineered for high-speed material removal on carbon steel. Built with 3M Precision Shaped Grain ceramic abrasive, it delivers faster cut rates and longer service life than conventional alumina fibre discs. The stiff fibre backing and strong resin bond resist tearing under aggressive load, making this disc a reliable choice for heavy-duty grinding tasks. Licensed tradespeople in fabrication, structural steel, and maintenance welding environments will find this disc well suited to demanding production cycles where disc longevity and consistent cut directly affect throughput.

This disc is designed for use on carbon steel in applications such as weld removal, weld blending, bevel grinding, edge chamfering, and surface finish refinement. The Precision Shaped Grain geometry maintains sharp cutting edges throughout the disc life, reducing the need for added pressure and operator fatigue during extended runs. It is compatible with standard 7-inch disc pad face plates and hubs sold separately by 3M.

Key Features

• 3M Precision Shaped Grain ceramic abrasive yields higher cut rates and more parts per disc than conventional abrasives
• Stiff fibre backing and strong resin bond provide durability and tear resistance under heavy load
• Suited for weld removal, beveling, blending, and edge chamfering on carbon steel
• 80 grit designation balances aggressive stock removal with surface refinement capability
• Compatible with 3M disc pad face plates and hubs (sold separately)
• Long-lasting abrasive mineral helps lower cost per part over the disc life

Compatibility

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

Installation Notes

Fibre discs of this type are installed and removed by a qualified operator using the appropriate 7-inch disc pad and hub assembly. Always power down and disconnect the grinder from its power source before mounting or changing the disc. Inspect the disc for cracks or damage before each use and do not exceed the maximum RPM rating marked on the disc or backing pad. Follow applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
