3M 7100099273 Quick Change Fibre Disc 782C 80 Grit 5 Inch

Product Description

The 3M 7100099273 is a 5-inch Quick Change coated fibre disc designed for aggressive material removal on carbon steel. Built on a stiff fibre backing with a strong resin bond, this disc uses 3M Precision Shaped Grain technology to deliver higher cut rates and longer service life compared to conventional abrasive discs. Rated at 12000 RPM, the 782C is suited for demanding metalworking tasks including weld removal, beveling, edge chamfering, and surface blending. At 80 grit, it removes material quickly while leaving a workable surface finish. Licensed tradespeople in fabrication and metal finishing rely on this disc for consistent results across high-volume applications.

This disc is intended for use on carbon steel in industrial and fabrication environments. Typical applications include weld grinding, bevel preparation, and finish blending on structural steel, plate work, and fabricated assemblies. The Quick Change mount allows fast disc swaps without additional tooling, making it practical for production environments where downtime matters. It is compatible with 3M disc pad face plates and hubs, which are sold separately.

Installation Notes

This disc is installed and serviced by metalworking tradespeople and fabricators. Before mounting, verify that the grinder RPM rating meets or exceeds the disc RPM rating of 12000. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or separation. Always use the appropriate 3M-compatible face plate and hub assembly, and ensure all guards are in place before operating.
