3M 7100099222 Quick Change Fibre Disc 80 Grit 7 Inch

Product Description

The 3M 7100099222 is a 7-inch coated quick-change fibre disc built for high-speed material removal on carbon steel. It runs at up to 8,600 RPM and uses 3M Precision Shaped Grain, an advanced abrasive geometry that delivers faster cut rates and longer service life than conventional alumina fibre discs. The stiff fibre backing and strong resin bond resist tearing under load, making this disc suitable for sustained, heavy-duty grinding. Licensed HVAC fabricators, sheet metal workers, pipefitters, and general metal tradespeople will find it well-suited to demanding production environments where disc life and cut consistency matter.

This disc is intended for use on carbon steel in applications that include weld removal, weld blending, bevel grinding, edge chamfering, and surface finish refinement. The 80-grit abrasive sits in the coarse-to-medium range, making it effective for aggressive stock removal before transitioning to finer finishing steps. It is designed for use with compatible quick-change disc pad face plates and hubs, which are sold separately. Minimum order quantity is 100 discs per purchase.

Key Features

• 3M Precision Shaped Grain provides higher cut rates and completes more parts per disc than conventional abrasives
• Rated to 8,600 RPM for use with standard angle grinders and disc grinders
• Stiff fibre backing and strong resin bond deliver tear-resistance under heavy grinding loads
• 80-grit coated abrasive suits weld removal, beveling, blending, and edge chamfering on carbon steel
• Quick-change attachment system reduces disc swap time during production runs
• Long-lasting abrasive construction helps lower cost per part over extended use

Compatibility

Designed for use with 3M disc pad face plates and hubs sold separately. Intended for carbon steel grinding and finishing applications on angle grinders and disc grinders that accept 7-inch quick-change fibre discs.

Installation Notes

Verify the grinder speed rating meets or exceeds the disc maximum of 8,600 RPM before mounting. Inspect the disc for cracks or tears before each use and discard any damaged disc immediately. Always use the appropriate 3M-compatible face plate and hub assembly to secure the disc properly. Follow ANSI B7.1 safety guidelines and wear appropriate PPE including a face shield and grinding-rated gloves during operation.
