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 leveling or moderate stripping. 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.
