3M 7100099289 Quick Change Disc 36 Grit 5 Inch

Product Description

The 3M 7100099289 is a quick-change coated fibre disc engineered for aggressive stock removal on hard-to-grind metals. Built with 3M Precision Shaped Grain, this 5-inch disc operates at up to 12,000 rpm and delivers higher cut rates and cooler grinding temperatures compared to conventional fibre discs. A grinding aid is bonded into the disc to reduce heat buildup, making it well suited for heat-sensitive alloys. Stiff fibre backing and a strong resin bond provide durability and resistance to tearing under heavy-load applications. Licensed tradespeople and fabricators in metal fabrication, welding, and finishing work install and operate this disc.

This disc is designed for weld removal, blending, beveling, edge chamfering, and finish refinement on stainless steel and high nickel alloys. The quick-change attachment system allows for fast disc swaps on compatible disc pad face plates and hubs, reducing downtime during production grinding and finishing operations. It is sold individually and fits into workflows where frequent disc changes and consistent cut performance are required on alloy and specialty metals.

Installation Notes

Mounting and operation of abrasive discs must be performed by personnel familiar with angle grinder safety practices. Ensure the grinder is powered off and unplugged before mounting or removing the disc. Verify that the grinder's rated speed meets or exceeds the disc's maximum operating speed of 12,000 rpm before use. Inspect the disc for cracks or damage before each use and never operate a damaged disc.
