3M 7100099036 Quick Change Fibre Disc 782C 36 Grit 5 Inch

Product Description

The 3M 7100099036 is a 5-inch quick-change coated fibre disc designed for high-rate material removal on carbon steel. Built around 3M Precision Shaped Grain technology, this disc delivers faster cut rates and longer service life compared to conventional abrasive fibre discs. The 36-grit ceramic abrasive is bonded to a stiff fibre backing using a strong resin bond, giving the disc the structural integrity needed for demanding grinding tasks. It is rated to 12,000 RPM and sized for use with standard 5-inch disc pad face plates and hubs. Fabricators, welders, and metalworkers rely on this disc for high-volume production grinding and surface prep.

The 7100099036 is suited for heavy-duty metalworking applications in industrial and fabrication shop environments. Primary use cases include weld removal, weld blending, beveling, edge chamfering, and surface finish refinement on carbon steel workpieces. The quick-change attachment system reduces downtime during disc swaps, making it well-suited to production settings where throughput matters. Compatible 3M disc pad face plates and hubs are sold separately and must be matched to the quick-change attachment style before installation.

Installation Notes

Installation should be performed by qualified personnel familiar with angle grinder safety and abrasive product handling. Verify that the grinder's maximum RPM rating meets or exceeds the disc's 12,000 RPM rating before mounting. Power down and disconnect the grinder from its power source before changing discs. Always inspect the disc for damage prior to use and operate with appropriate eye, face, and hand protection in accordance with applicable workplace safety standards.
