3M Sanding Sheet 9x11 Aluminum Oxide 346U

In Packaging?: Yes

Damaged?: Unknown


General purpose sandpaper sheets optimized for use on all surfaces have an open-coat aluminum oxide abrasive applied to a paper backing. Aluminum oxide is a strong, sharp, and durable abrasive that penetrates the work surface and withstands heat and high speeds. Open-coat abrasives have grit on about 50% of the surface leaving space between the abrasive grains to prevent swarf from clogging the surface which keeps the workpiece cooler. The paper backing provides a smooth, flat surface to provide consistent pressure across the work surface. Compatible surfaces and substrates include paint, plastic, composites, gelcoat, fiberglass, and carbon steel.
