3M 7000120881 Hook Loop Abrasive Disc 7 in Aluminum Oxide

Product Description

The 3M 7000120881 is a 7-inch hook and loop non-woven abrasive disc designed for surface conditioning, finishing, and blending applications. Built around aluminum oxide abrasive material at a medium grade, it attaches and removes quickly from compatible hook and loop backup pads. The disc is flexible, conforming to contoured surfaces without losing consistent cut. It is rated to a maximum of 6,000 RPM, making it suitable for use with standard right-angle grinders and disc sanders used by metalworkers, maintenance technicians, and fabricators.

This disc fits surface preparation tasks in both commercial and industrial settings. Its non-woven construction open up the abrasive matrix, helping reduce loading when working on metals, composites, or painted surfaces. The maroon color indicates medium-grade cut, which is appropriate for general deburring, weld blending, and surface scratch removal. The SE-DH series designation and AMED specification identify it within the 3M surface conditioning product line. No vacuum holes are included, which simplifies use on standard non-perforated backup pads.

Installation Notes

Mounting and removal require only a compatible hook and loop backup pad — no tools needed for disc changes. Confirm the tool and backup pad are rated to at least the disc maximum speed of 6,000 RPM before operation. Inspect the disc for tears or separation before each use and discard damaged discs immediately. Always wear appropriate PPE including eye protection and gloves when operating abrasive discs.
