3M 7100089199 Aluminum Oxide Sanding Sheets 220 Grit

Product Description

The 3M 7100089199 is an aluminum oxide abrasive sanding sheet designed for general-purpose material removal including paint stripping and rust removal on a range of surfaces. Measuring 9 inches x 11 inches and rated at 220 grit, these sheets are suited for finish sanding and surface prep work where a consistent cut and smooth result are required. Aluminum oxide abrasive is a durable, self-fracturing mineral that maintains a sharp cutting edge through the life of the sheet, making it a reliable choice for production and detail sanding tasks on metal and painted surfaces.

These sanding sheets are appropriate for use in light industrial, automotive refinishing, and general trade applications where surface preparation is a routine step. The 220 grit rating places them in the fine abrasive range, suitable for scuffing between coats, final prep before priming, and smoothing surface rust before treatment. They can also be used for general sanding tasks on a variety of substrates. The sheets are sold in a pro-pak format, providing a quantity-ready supply for shop or field use.

Installation Notes

Abrasive sheets are installed by trade professionals and skilled technicians in automotive, HVAC sheet metal, and general fabrication settings. Ensure the sanding block or tool backing pad is clean and free of debris before loading the sheet to prevent uneven wear. When sanding near electrical components or in confined spaces, power down adjacent equipment and follow applicable shop safety protocols. Wear appropriate respiratory protection when sanding painted surfaces that may contain lead-based coatings.
