3M 7000045979 Roloc Tr 2 in Quick-change Disc Aluminum Oxide

Product Description

The 3M 7000045979 is a Roloc TR quick-change abrasive disc designed for surface conditioning, blending, and finishing on metal and other hard substrates. Built on a non-woven construction with aluminum oxide abrasive at a medium grade (density 6), this disc mounts quickly to any Roloc TR-compatible right-angle die grinder or finishing tool. At 2 inches in diameter and rated to 22,100 RPM, it handles tight access areas and contoured surfaces where larger discs cannot reach. It is well suited for deburring, weld blending, and light stock removal in fabrication and HVAC sheet metal work.

This disc is used in light industrial, fabrication shop, and field service environments where fast disc changes and consistent surface finish matter. It is appropriate for use on mild steel, stainless steel, aluminum, and similar metals. The 2-inch format fits compact Roloc TR tool heads, making it useful for detail work around fittings, flanges, and weld joints. HVAC technicians, pipefitters, and sheet metal workers commonly use this disc size for spot finishing and seam cleanup during installation or rework.

Installation Notes

Installation is performed by a trained technician or skilled trade worker using a Roloc TR-compatible die grinder. Inspect the disc for damage before mounting and confirm the tool spindle speed does not exceed the 22,100 RPM disc rating. Always wear appropriate PPE including eye protection and gloves when operating abrasive discs. Ensure the workpiece is secure and the tool is fully powered down before changing discs.
