Norton 9 in. x 11 in. 320 Grit Aluminum Oxide Sandpaper Sheet

The Norton 9 in. x 11 in. 320 Grit Aluminum Oxide Sandpaper Sheet is engineered for superior surface preparation and finishing. Featuring premium heat-treated aluminum oxide abrasive grains, this sanding sheet delivers an aggressive cut and extended life compared to standard abrasives. The specialized grain treatment allows it to stay sharp under heavy use, making it ideal for tough sanding applications. Built with a fiber-reinforced, latex-saturated paper backing, this sheet provides exceptional tear resistance while remaining flexible enough for folding. The non-pigmented, water-based stearate open coat prevents clogging and loading without transferring dye to the workpiece, making it suitable for wood, fiberglass, composites, carbon steel, and non-ferrous metals.
