3M 7010326789 Quick-change Disc 36 Grit 2 in Ceramic

Product Description

The 3M 7010326789 is a 2-inch ceramic coated quick-change abrasive disc designed for aggressive material removal on metal and composite surfaces. Built on a polyester cloth backing with a YF backing weight, this disc uses Premium Ceramic Alumina abrasive at 36 grit — a very coarse grade suited for rapid stock removal, weld blending, and surface conditioning. The maroon disc is rated to 25,000 RPM and attaches via the Roloc TR (Type III) quick-change system, allowing fast disc swaps without tools. It is part of the 3M 984F series and is installed by metal fabricators, welders, HVAC sheet metal technicians, and industrial maintenance trades.

This disc is intended for use with TR-compatible right-angle grinders and die grinders in both shop and field environments. At 2 inches in diameter, it suits tight-access grinding, deburring, and surface prep on ductwork, pipe ends, structural steel, and fabricated metal components. The very coarse 36-grit cut rate makes it most effective for initial material removal passes rather than finish work. Sold as a single disc per package.

Installation Notes

Installation requires a Roloc TR-compatible mandrel or holder mounted to a die grinder or right-angle grinder. Ensure the tool is powered off and disconnected from the air supply or electrical source before mounting or removing the disc. Inspect the disc for damage before each use and confirm the tool's free-speed RPM does not exceed the disc's 25,000 RPM rating. Eye protection and appropriate PPE are required during operation per standard shop safety practice.
