3M 7100100982 Roloc Fibre Disc 787C 2 Inch 60 Grit

Product Description

The 3M 7100100982 is a 2-inch coated abrasive fibre disc in the 787C series, designed for rapid stock removal on hard-to-grind metals. Built around 3M Precision Shaped Grain, the disc delivers higher cut rates and a cooler grinding action compared to conventional fibre discs. A built-in grinding aid controls heat buildup, making this disc well suited for heat-sensitive alloys. The Roloc attachment system locks the disc onto compatible backup pads without tools. At 60 grit and a rated speed of 30000 RPM, it is sized for aggressive material removal in a compact format. Metalworkers, fabricators, and maintenance technicians are the primary installers.

This disc is intended for weld removal, blending, beveling, edge chamfering, and finish refinement on stainless steel and high nickel alloys. The stiff fibre backing and strong resin bond resist tearing under sustained load, supporting heavyweight grinding tasks in both shop and field environments. Its 2-inch diameter makes it practical for tight access areas and detail work on fabricated assemblies where larger discs cannot reach.

Compatibility

Designed for use with Roloc-compatible backup pads and angle grinders or die grinders rated for 2-inch discs at a minimum of 30000 RPM.

Installation Notes

Installation is performed by metalworking and fabrication professionals. Confirm the grinder speed rating meets or exceeds the 30000 RPM disc rating before mounting. Inspect the disc for damage before each use and discard any cracked or torn discs. Always wear appropriate personal protective equipment including eye protection and gloves when operating grinding equipment.
