3M 7000120780 Scotch-brite Sc-dh Disc 27 Inch Non-woven

Product Description

The 3M 7000120780 is a Scotch-Brite SC-DH Surface Conditioning Disc built for right-angle grinder use in cleaning, blending, deburring, and finishing applications. The disc measures 27 inches in diameter and features a durable non-woven fiber construction that conforms to irregular and contoured surfaces. Its open-web abrasive material runs cool during extended use and resists loading, helping maintain consistent cut performance across multiple passes. The hook-and-loop attachment system allows fast disc changes, making it well suited for multi-step finishing workflows. The abrasive type is aluminum oxide (AO). This disc is used by metalworkers, fabricators, and finishing technicians across industrial and trade settings.

The SC-DH disc is designed for use on metal, composite, plastics, and similar materials where surface prep or finishing is required without gouging or undercutting the base material. It is a practical first-step tool in surface conditioning sequences, including weld blending, light deburring, and prep work before coating or inspection. The large 27-inch diameter makes it appropriate for wide flat surfaces or large contoured workpieces where full coverage and consistent finishing are priorities. Minimum order quantity is 2 discs per purchase.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source.

Secure the hook-and-loop backing firmly before operating to prevent disc separation during use. Wear appropriate PPE including eye protection and gloves when operating abrasive discs.
