3M 7100099242 Quick Change Fibre Disc 60 Grit 7 Inch

Product Description

The 3M 7100099242 is a 7-inch Quick Change fibre disc designed for aggressive material removal on hard-to-grind metals. Built with 3M Precision Shaped Grain, it delivers higher cut rates and cooler grinding temperatures compared to conventional abrasive discs. A grinding aid is bonded into the construction to further reduce heat buildup, making it well suited for heat-sensitive alloys. The disc runs at a maximum of 8600 RPM and carries a 60-grit rating. A stiff fibre backing and strong resin bond resist tearing under heavy load. Licensed HVAC techs, fabricators, and welding professionals rely on this disc for demanding production grinding tasks.

This disc is engineered for weld removal, blending, beveling, edge chamfering, and finish refinement on stainless steel and high nickel alloys in both shop and field environments. The quick-change attachment system allows for fast disc swaps without additional tooling, reducing downtime during high-volume grinding operations. It is sold individually and is compatible with 3M disc pad face plates and hubs, which are sold separately.

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on stainless steel and high nickel alloys in weld grinding, blending, and finish refinement applications.

Installation Notes

Mounting and disc changes should be performed by qualified personnel with the grinder fully powered off and unplugged. Verify the grinder RPM rating meets or exceeds the disc maximum of 8600 RPM before use. Inspect the disc for damage before each use and do not use a disc that shows signs of cracking or delamination. Always use appropriate personal protective equipment including face shield and gloves when operating grinding equipment.
