3M 7100063976 Scotch-brite Sc-dh Disc 48 Inch Non-woven Ao

Product Description

The 3M 7100063976 is a Scotch-Brite SC-DH Surface Conditioning Disc built for cleaning, blending, deburring, and finishing operations in professional fabrication and surface prep environments. At 48 inches in diameter, this non-woven disc uses an aluminum oxide (AO) abrasive mineral bonded into an open-web fiber construction. The open web runs cool under load and resists clogging, extending usable life during multi-pass finishing work. The disc mounts via a hook and loop attachment system designed for right-angle tool use. Licensed tradespeople, fabricators, and industrial maintenance techs working with metal, composite, or plastic substrates will find this a reliable first-step abrasive.

This disc is suited for surface conditioning tasks on flat, irregular, and contoured workpieces across a range of base materials including metal, composites, and plastics. The conformable non-woven construction follows surface contours without undercutting or damaging the substrate, making it appropriate for both preparatory and finishing stages. Typical applications include weld blending, mill scale removal, light deburring, and pre-coat surface prep in manufacturing, fabrication shop, and maintenance environments. The hook and loop system supports fast disc changes during multi-step finishing sequences, reducing downtime between abrasive grades.
