3M 7000136529 Scotch-brite 7 Inch Surface Conditioning Disc

Product Description

The 3M 7000136529 is a non-woven surface conditioning disc designed for right-angle grinders and sanders using a hook-and-loop attachment system. Built on an open-web fiber construction, the disc conforms to irregular, contoured, and complex surfaces without gouging or undercutting the base material. It is well suited for cleaning, blending, deburring, and finishing operations across metal, composite, plastic, and other substrates. The open-web structure allows heat to dissipate during use and resists loading, extending disc life across multi-step finishing workflows. At 7 inches in diameter, it is a standard size for angle grinder applications in fabrication and maintenance environments.

This disc is used in fabrication shops, maintenance facilities, and manufacturing environments where surface conditioning is a routine part of the workflow. It performs in both light industrial and trade settings, including metalworking, composite repair, and general surface prep. The hook-and-loop mount makes it practical for multi-step processes where disc changes between grades need to happen quickly. It is appropriate for use on a wide range of materials, making it a versatile option for technicians and fabricators working across different substrates in a single session.
