3M 7000000751 Quick-change Disc 2 in Medium Roloc Tr

Product Description

The 3M 7000000751 is a 2-inch non-woven aluminum oxide quick-change disc rated for surface conditioning and finishing work. The disc mounts via a Roloc TR (Type III) attaching system for fast one-handed attachment and removal on compatible right-angle tools. It carries a medium grade cut and is rated to a maximum of 25,000 RPM. The maroon non-woven construction allows it to conform to irregular surfaces while resisting loading, making it well-suited for blending, deburring, and light surface prep on metal and similar substrates. Licensed tradespeople and fabricators in HVAC, plumbing, and general metalwork use this disc for cleaning weld areas, prepping fittings, and removing light oxidation before assembly.

This disc is intended for use in light to medium surface conditioning applications on ferrous and non-ferrous metals. Typical install scenarios include preparing pipe and fitting surfaces before brazing or mechanical joining, cleaning heat exchanger components, and deburring sheet metal edges. The 2-inch diameter is well matched to confined areas and smaller angle grinders or die grinders where access is limited. Each package contains one disc, with a minimum order quantity of 25 discs.

Installation Notes

This disc is installed and removed by a licensed or qualified tradesperson using a compatible Roloc TR mandrel on a die grinder or right-angle grinder. Ensure the tool is powered down and disconnected from its air or electrical supply before changing discs. Do not exceed the 25,000 RPM maximum speed rating. Wear appropriate eye and face protection during all grinding and surface conditioning operations per applicable safety standards.
