2Sand.com sells heavily discounted Sanding Belts. We sell aluminum oxide sanding belts and silicon carbide sanding belts. Aluminum Oxide can be bought in open and closed coat. As probably the most widely used sanding abrasive, you can use aluminum oxide for most all wood working projects. Silicon Carbide is black and is mostly used for cutting stone, tile, and glass. The grits on silicon carbide are finer than the ones on the aluminum oxide. Other belts we sell include bandsaw belts, and wide belts.
