3M 09191, SandBlaster Sanding Belts 9191NA 3 in x 21 in, 7010383389, 10 per case

3M SandBlaster sanding belts are ideal for use on many surfaces, including wood, metal, and fiberglass. SandBlaster power tool abrasives were designed especially for high speed power tool sanding. This sanding belt was specially developed for surface smoothing. The heavy duty cloth backing is coated with extremely durable Cubitron mineral, which stays sharp resulting in less surface burning, a more consistent sanded surface, and a longer life, when compared to 3M’s conventional belts.
