3M 7100099246 Quick Change Fibre Disc 787C 7 Inch 60 Grit

Product Description

The 3M 7100099246 is a 7-inch Quick Change coated fibre disc designed for aggressive material removal on hard-to-grind metals including stainless steel and high nickel alloys. Built around 3M Precision Shaped Grain technology, this 60-grit disc delivers higher cut rates and a cooler cut 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 alloys. The disc is backed by a stiff fibre backing and a strong resin bond for durability and tear resistance. It is rated to 8600 RPM. Metalworking professionals and fabricators are the primary installers and users of this disc.

This disc is intended for heavy-duty metalworking applications including weld removal, weld grinding, beveling, blending, edge chamfering, and finish refinement. It is particularly effective on stainless steel and high nickel alloy workpieces where heat control and consistent cut rate are critical. The quick-change attachment style allows fast disc swaps, supporting high-volume production and job-site efficiency. Compatible disc pad face plates and hubs are sold separately.
