3M 7000120957 Quick Change Disc 7 Inch Non-woven

Product Description

The 3M 7000120957 is a quick-change, non-woven surface conditioning disc designed for cleaning, blending, deburring, and finishing applications on a wide range of materials. Built with an open-web, non-woven fiber construction, the disc conforms to irregular and contoured surfaces without undercutting or damaging the base material. At 7 inches in diameter, it mounts to right-angle grinders and similar tools via a hook-and-loop attachment system, making disc swaps fast during multi-step finishing processes. Weighing 0.19 pounds, it is a practical addition to any metal fabrication or surface prep workflow. Licensed tradespeople and skilled fabricators working with metal, composites, and plastics rely on this disc for consistent, controlled surface conditioning.

This disc is suited for residential and commercial fabrication, maintenance, and repair environments where surface prep is a recurring task. Its conformable construction makes it effective on curved, contoured, or irregular workpiece profiles that rigid abrasives struggle to address. The open-web material runs cool and resists loading, supporting prolonged operation without frequent disc changes. It is appropriate for use on metal, composite, plastics, and other materials in light deburring, blending, and finishing stages.

Installation Notes

Installation is performed by tradspeople and fabricators familiar with angle grinder operations. Before mounting, ensure the tool is fully powered off and disconnected from its power source. Attach the disc securely to a matching hook-and-loop backing pad before initiating tool operation. Follow applicable workplace safety standards and wear appropriate personal protective equipment including eye and face protection when operating abrasive discs.
