3M 7000045622 Quick-change Disc 120 Grit Ceramic 1 Inch

Product Description

The 3M 7000045622 is a ceramic-abrasive quick-change disc designed for use with Roloc TR (Type R) attachment systems on right-angle grinders and die grinders. Part of the 3M 777F series, this 1-inch disc uses a ceramic abrasive grain bonded to a polyester cloth backing rated at a YF backing weight. It operates at up to 30,000 RPM and cuts at a fine 120-grit level, making it suited for light deburring, surface blending, and fine finishing passes on metal workpieces. The orange-colored disc with a white button is sold individually, with a minimum order quantity of 50 units.

This disc is intended for use in metal fabrication, maintenance, and finishing applications where a compact 1-inch format is required. The Type R quick-change system allows for rapid disc swaps without additional hardware. Typical applications include weld blending, edge deburring, and fine surface conditioning on ferrous and non-ferrous metals. It is used by metal fabricators, maintenance machinists, and industrial technicians working in tight spaces or on small workpiece features where a larger disc would be impractical.

Installation Notes

Install only on grinders fitted with a compatible Type R mandrel. Verify the grinder's rated free speed does not exceed the disc's 30,000 RPM maximum before mounting. Inspect the disc for damage before each use and do not use damaged or deformed discs. Always wear appropriate eye and face protection when operating abrasive discs.
