Product Overview:

When you are sanding metal, the belt tells the truth pretty quickly. This 3M Cubitron II sanding belt gives you a sharp, steady bite on tough surfaces, and it does not wear out in a blink. If you work on high-strength steel or hard metal, you know the grind. This one helps keep the pace sensible.

Set it in place and you will feel the smoother pull, hear less drag, and see a cleaner finish without the usual fuss.
