3M 7100185231 Fibre Disc 60 Grit 9.125 in 7/8 in Arbor

Product Description

The 3M 7100185231 is a coated fibre disc engineered for ultra-rapid cutting on carbon steel. It uses 3M Precision Shaped Grain, an advanced abrasive mineral that delivers higher cut rates and longer service life compared to conventional fibre discs. Measuring 9.125 inches in diameter with a 7/8 inch arbor, this disc mounts to standard angle grinders and disc pads used in metal fabrication shops, structural steel work, and heavy industrial maintenance. The stiff fibre backing and strong resin bond resist tearing under load, making it well suited for aggressive stock removal tasks at 60 grit.

This disc is used in applications where fast, consistent cutting on carbon steel is required. Typical jobs include weld removal, weld blending, surface preparation, beveling, edge chamfering, and finish refinement on plate steel, structural members, and fabricated assemblies. It is installed by welders, pipefitters, ironworkers, and metal fabrication professionals working in both shop and field environments. The 60 grit rating positions it for heavy material removal while still leaving a workable surface profile for follow-on finishing steps.

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on carbon steel in weld removal, blending, and surface preparation applications.

Installation Notes

Installation and disc changes must be performed by qualified personnel with the grinder fully powered off and unplugged or locked out per applicable OSHA lockout/tagout procedures. Verify the grinder spindle speed rating meets or exceeds the disc maximum RPM before mounting. Inspect the disc for cracks or damage before each use and discard any disc that shows visible defects. Always use the appropriate disc pad face plate and hub for secure seating.
