3 X 21 Inch Silicon Carbide Sanding Belts, 8 Pack

Works great on concrete fast shipping

On fiberglass, these silicon carbide belts last much longer than less expensive box store alternatives. They remove a lot if material, yet do not heat up the worked surface. I am on one belt on a job that would have already gone through several cheap ones, and there is still plenty of bite left. Well worth the added cost.

I was working on repairing my front stairs and needed belt grinding belts to finish concrete. These belts worked great .
