3M 7100007040 Scotch-brite Roloc Disc 4 Inch 12000 Rpm

Product Description

The 3M 7100007040 is a Scotch-Brite Roloc Surface Conditioning Disc designed for grinding, blending, finishing, deburring, and cleaning metal and other surfaces. It uses a non-woven fiber construction that conforms to irregular and contoured workpiece profiles, reducing the risk of gouging or over-cutting. The disc mounts via the Roloc quick-change attachment system, which allows fast, tool-free disc swaps during multi-step finishing operations. At a 4-inch diameter and rated to 12000 RPM, it fits standard right-angle grinders and die grinders equipped with a Roloc-compatible mandrel. Metalworkers, fabricators, and maintenance technicians are the primary users of this disc.

This disc is suited for light to moderate metal surface preparation tasks including weld blending, edge deburring, surface scale removal, and pre-paint or pre-coat finishing. The open-web fiber structure resists loading, meaning it sheds swarf and debris rather than clogging, which helps maintain a consistent cut rate and finish quality across the life of the disc. It performs on steel, stainless steel, aluminum, and similar metals. The quick-change backing makes it practical for production environments where operators rotate through multiple abrasive grades or product types in sequence.

Installation Notes

Mounting and disc changes should be performed with the grinder powered off and unplugged or air supply disconnected. Verify the grinder spindle speed does not exceed the 12000 RPM rating of the disc before operation. Inspect the disc for damage before each use and discard any disc that shows tears, delamination, or backing separation. Follow applicable ANSI and OSHA abrasive wheel safety standards when operating grinding equipment.
