3M 7100310732 Fiber Disc 36 Grit 7 in Quick Change Tn

Product Description

The 3M 7100310732 is a 7-inch fiber-backed coated abrasive disc designed for aggressive material removal on metal, weld seams, and fabricated surfaces. Running on a Quick Change TN attachment system, the disc mounts and dismounts without tools, reducing downtime during high-volume grinding operations. The abrasive material is Premium Ceramic Alumina bonded with a resinoid bond to a fiber backing, delivering consistent cut rate and extended disc life under heavy load. Rated to 8,600 RPM, it is suited for use with compatible angle grinders and disc grinders in industrial and trade fabrication settings. At 36 grit, it falls in the Extra Coarse grade range for fast stock removal.

This disc is used in metal fabrication shops, structural steel work, shipbuilding, and general welding cleanup where rapid surface conditioning or weld blending is needed. The Quick Change TN hub allows technicians to swap discs quickly on compatible backing pads without hand tools, making it practical for production-line grinding and multi-pass operations. It is appropriate for use on carbon steel, stainless steel, and other hard metals requiring aggressive initial cutting action before finer finishing steps.

Compatibility

Designed for use with Quick Change TN-compatible backing pads on angle grinders and disc grinders rated to accept 7-inch fiber discs at or below 8,600 RPM.

Installation Notes

This disc should be installed and removed by a qualified operator familiar with abrasive grinding equipment. Always power down and disconnect the grinder from its power source before mounting or dismounting the disc. Verify the backing pad is rated for Quick Change TN discs and that the grinder RPM does not exceed the 8,600 RPM disc rating. Inspect the disc for cracks or damage before each use and discard any disc showing signs of delamination or edge fraying.
