3M 7000028184 Quick-change Disc 2 in 50 Grit Aluminum Oxide

Product Description

The 3M 7000028184 is a quick-change abrasive disc designed for use with Roloc TR Type R attaching systems. Part of the 3M 361F series, it features a 2-inch diameter and 50-grit aluminum oxide abrasive bonded to a polyester cloth backing with a YF backing weight. The coarse-grade aluminum oxide cuts efficiently on metal, weld seams, and welds during grinding and blending operations. Rated to 25,000 RPM, it handles aggressive material removal while the brown coated construction resists loading. Licensed tradespeople in metal fabrication, HVAC, and general industrial trades use this disc for surface prep and stock removal tasks.

This disc fits standard Roloc TR Type R quick-change disc holders and backup pads. It is suited for use on ferrous and non-ferrous metals in both shop and field settings. Typical applications include weld blending, deburring, edge chamfering, and surface conditioning on sheet metal, pipe, and structural components. The coarse 50-grit cut rate makes it effective where fast material removal is the priority before finishing steps.
