3M 7000045092 Quick-change Disc 1 Inch 36 Grit Aluminum Oxide

Product Description

The 3M 7000045092 is a Roloc TR quick-change abrasive disc designed for aggressive material removal in grinding, blending, and surface preparation applications. Built on a rigid cloth backing with a YF backing weight, this coated disc uses aluminum oxide abrasive at 36 grit — a very coarse grade suited for fast stock removal on metal, welds, and composite surfaces. The Type R attaching system allows fast disc swaps without tools, reducing downtime during repetitive surface work. Rated to 30,000 RPM, the disc is manufactured in the 3M 361F series and carries a brown color designation consistent with that product line.

This disc is intended for use with Roloc TR and Type R compatible disc holders on die grinders and right-angle grinders. It fits the 1-inch disc diameter category, making it well suited for tight-access work, deburring, weld seam blending, edge conditioning, and rust or scale removal in fabrication, maintenance, and repair environments. It is commonly used by metal fabricators, industrial maintenance technicians, pipefitters, and welders working on ferrous and non-ferrous metals.

Installation Notes

Install on a compatible Type R mandrel by pressing the disc onto the holder and rotating to lock. Always verify the tool RPM rating does not exceed the 30,000 RPM disc maximum before operation. Wear appropriate eye and face protection, and inspect the disc for damage before each use. Follow applicable ANSI B7 safety standards and the grinder manufacturer guidelines for abrasive disc mounting.
