3M 7100075692 Psa Disc 5 in 220 Grit Ceramic Film

Product Description

The 3M 7100075692 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface finishing and fine material removal. Part of the 3M 775L Series, this disc features a ceramic abrasive mineral bonded to a flexible film backing. The very fine 220-grit cut makes it suited for light stock removal, blending, and prep work on wood, composites, and finished surfaces. The film backing provides a consistent, flexible cut that conforms to contoured surfaces. No vacuum holes are included. Each unit ships individually; minimum order quantity is 250 discs.

This disc is intended for use with random orbital sanders in both shop and field applications. The PSA mount allows fast disc changes without mechanical fasteners. The 775L Series purple ceramic discs are a common choice for finish sanding operations in woodworking, automotive body prep, and light metalworking environments. The flexible film backing reduces the risk of chatter marks on flat and slightly curved workpieces, making this disc appropriate for final surface prep stages prior to coating or finishing.

Installation Notes

Ensure the sander backing pad is clean and free of debris before applying the PSA disc; contamination reduces adhesion and shortens disc life. Press the disc firmly and evenly onto the pad before use. Operate the sander at the speed recommended by the tool manufacturer for the workpiece material. Worn or glazed discs should be replaced promptly to maintain consistent cut rate and surface quality.
