3M 7000121098 Scotch-brite Sc-dh Surface Conditioning Disc 7 in

Product Description

The 3M 7000121098 Scotch-Brite SC-DH is a 7-inch non-woven surface conditioning disc designed for right-angle grinder use with a hook-and-loop attachment system. Built from durable open-web nylon fiber impregnated with aluminum oxide (AO) abrasive, it is used for cleaning, blending, deburring, and finishing on metal, composite, plastic, and other materials. The open-web construction runs cool and resists loading, extending disc life during prolonged operation. Licensed tradespeople, fabricators, and finishing technicians working on contoured or irregular surfaces rely on this disc where a rigid abrasive would gouge or undercut the base material.

The SC-DH disc suits residential and commercial metalworking, fabrication, and surface prep applications. Its conformable non-woven fiber construction allows it to follow contours and irregular profiles without damaging underlying material. The hook-and-loop attachment makes it easy to swap discs quickly during multi-step finishing sequences. It is suitable for use on steel, aluminum, composite panels, plastics, and similar substrates where a controlled, consistent surface condition is required before priming, coating, or further finishing steps.
