Blair Rotabroach cutters are ideal for heavy duty use in sheet metal and other materials up to 1/2" thick. Blair 11,000 series cutters have multiple cutting teeth to extend the life of the cutter as well as a more precise cut every time. Annular tools that cut clean, burr-free, and round holes fast.. unlike twist drills that push or hole saws that tear through materials. Because they’re hollow, there’s no dead zone as with a twist drill. That means less thrust is required which eliminates jagged edges and deformities.
