3M 7000119242 Psa Disc 6 in 100 Grit Silicon Carbide 125 Pack

Product Description

The 3M 7000119242 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface preparation, finishing, and material removal in trade and industrial applications. Built on a lightweight A-weight paper backing with a silicon carbide abrasive layer, this disc delivers consistent cut at 100 grit — a fine grade suited for smoothing, blending, and prep work on wood, composites, and non-ferrous metals. The gray disc measures 6 inches in diameter with no vacuum holes, and the package contains 125 discs. It carries the 3M 426U series designation and is part of the 3M coated abrasives line used widely in finishing shops, fabrication facilities, and field service applications.

This disc is designed for use with random orbital sanders accepting 6-inch PSA-style discs. The pressure-sensitive adhesive backing allows for quick, tool-free attachment and removal directly to the sander pad. It is well suited for residential and commercial finishing work including cabinetry, trim carpentry, composite panel work, and light metal finishing. The flexible paper backing conforms to slightly contoured surfaces, making it useful in both flat-surface and mild-profile applications. Installers and finishing tradespeople will find the 125-disc pack format practical for ongoing production work.

Installation Notes

Power down and unplug the random orbital sander before changing discs. Peel the paper liner from the PSA backing and press the disc firmly onto a clean, dry sander pad to ensure full adhesive contact. Avoid applying discs to worn or contaminated pads, as poor adhesion can cause disc separation during use. Dispose of spent discs per local waste guidelines for coated abrasives.
