3M 7100099292 Quick Change Fibre Disc 787C 5 Inch 36 Grit

Product Description

The 3M 7100099292 is a 5-inch quick-change coated fibre disc designed for aggressive material removal on hard-to-grind metals. Built around 3M Precision Shaped Grain, this disc delivers higher cut rates and a cooler grinding action compared to conventional fibre discs. A grinding aid is integrated into the construction to minimize heat buildup during use, making it well-suited for heat-sensitive materials. Rated to 12000 RPM, it is engineered for weld removal, blending, beveling, edge chamfering, and finish refinement in demanding fabrication and metalworking environments. Licensed trade professionals and fabricators in metal finishing and welding applications are the primary installers.

This disc is used in industrial and commercial metalworking settings where aggressive stock removal on stainless steel and high nickel alloys is required. Typical applications include weld grinding, bevel preparation, and surface blending in fabrication shops and field repair scenarios. The stiff fibre backing and strong resin bond provide durability and tear-resistance under sustained load. Compatible with 3M disc pad face plates and hubs, which are sold separately.
