3M 7100044582 Quick-change Disc 100 Grit 1 Inch Roloc Tr

Product Description

The 3M 7100044582 is a Roloc TR quick-change abrasive disc designed for surface finishing, blending, and material removal on metal and other substrates. Part of the 3M 361F series, it features a 1-inch diameter with a 100-grit aluminum oxide abrasive coating on a polyester cloth backing rated for a YF backing weight. The Type R attachment system locks and releases with a quarter-turn motion, allowing fast disc swaps without tools. Rated to 30,000 RPM, this disc is suited for use with compatible high-speed die grinders and rotary tools. It is sold individually with a minimum order quantity of 50 units.

This disc is used in metal fabrication, automotive bodywork, aerospace maintenance, and general industrial applications where controlled, fine-grade surface prep is required in tight or contoured areas. The 1-inch diameter makes it well suited for detail work, weld blending, deburring, and surface conditioning in areas inaccessible to larger discs. Typical users include metal fabricators, auto body technicians, maintenance mechanics, and industrial finishing professionals working with ferrous and non-ferrous metals.

Installation Notes

Installation requires a Roloc TR-compatible mandrel mounted in a die grinder or rotary tool. Confirm the tool spindle speed does not exceed the 30,000 RPM disc rating before operation. Allow the tool to come to a complete stop before changing discs. Always wear appropriate eye and face protection and follow applicable ANSI B7 safety standards for abrasive products.
