3M Company 9003NA Aluminum Oxide Sandpaper 60 Grit 4 Pack

Product Description

The 3M COMPANY 9003NA is a 60-grit aluminum oxide production sandpaper sheet designed for aggressive material removal in woodworking and metalworking applications. Each sheet measures 9 inches x 11 inches and is sold in a 4-pack format, making it a practical restocking option for shops and job sites. Aluminum oxide is a durable abrasive mineral that fractures during use to continuously expose fresh cutting edges, maintaining consistent cut rate across the life of the sheet. This sandpaper is built for production-level sanding where speed and stock removal take priority over fine finishing.

This sandpaper is suited for both woodworking and metalworking tasks. Common applications include leveling rough lumber, removing mill scale from steel, prepping welds, and stripping old finishes from wood surfaces. The 9-inch x 11-inch sheet size fits standard hand sanding blocks and can be cut or folded to fit most hand-pad applications. It is appropriate for both residential shop use and light commercial or contractor settings where volume sanding is routine.

Installation Notes

No power tools or mechanical fastening are required for hand-sheet sanding applications. When using with a sanding block, ensure the sheet is seated flat and secure before beginning work. When sanding metal, wear appropriate eye protection and a dust mask rated for fine metallic or wood particulate. Dispose of used abrasive sheets in accordance with local waste guidelines, particularly when sanding lead-based paints or treated materials.
