3M 7100099031 Quick Change Fibre Disc 5 Inch 60 Grit

Product Description

The 3M 7100099031 is a quick-change coated fibre disc designed for aggressive material removal on carbon steel and similar ferrous metals. Built around 3M Precision Shaped Grain abrasive technology, the 782C disc delivers higher cut rates and longer service life than conventional fibre discs. At 5 inches in diameter and rated to 12000 RPM, it is sized for standard angle grinders and disc grinders used in fabrication, maintenance, and repair environments. The stiff fibre backing and strong resin bond resist tearing under heavy load, making this disc well suited to demanding production work.

The 7100099031 is intended for tough metalworking applications including weld removal, weld blending, edge beveling, edge chamfering, and surface finish refinement on carbon steel. The quick-change attachment system allows for fast disc swaps during production runs. This disc is a fit for fabrication shops, structural steel work, pipeline work, and heavy equipment repair where removal rate and disc longevity are priorities for the grinding technician.
