Tungsten Carbide Cutters Last Almost Forever
You've never seen anything like these incredible cutters. They're made of virtually indestructible tungsten carbide welded to steel shanks. They'll last for years and they won't load up, break down or overheat like ordinary steel cutters. Use on all woods, fiberglass, stone, ceramic or plastic (not recommended for use on metal). 1/8 inch shanks fit in hand drills, rotary tools and drill presses.
