3M 7000120660 Scotch-brite 3 Inch Coarse Conditioning Disc

Product Description

The 3M 7000120660 is a Scotch-Brite surface conditioning disc designed for cleaning, blending, deburring, and finishing on a wide range of materials. Built with a durable, non-woven fiber construction, the disc conforms to irregular and contoured surfaces without gouging, undercutting, or damaging the base material. The open web design runs cool and resists loading, allowing for extended operation without frequent disc changes. At 3 inches in diameter, this disc is sized for right-angle grinder use and is suited to metal, composite, plastics, and similar substrates. It is a go-to first-step disc for surface prep work in fabrication, maintenance, and finishing applications.

This disc is used in light industrial, fabrication, and maintenance settings where surface conditioning is required before coating, welding, or final finishing. The coarse aluminum oxide abrasive grade makes it effective at initial material removal and surface cleaning. The hook-and-loop attachment system allows fast, tool-free disc swaps, which is practical in multi-step finishing workflows. Typical users include metal fabricators, maintenance technicians, and trade professionals working on structural steel, tubing, sheet metal, and composite components.
