Features and Benefits:

Blair 11,000-SERIES ROTABROACH CUTTERS... for heavy duty use in sheet metal & materials up to 1/2" thick. 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, so less thrust is required and no deforming of stock or jagged edges occurs. Multiple cutting teeth, precision ground instead of stamped like hole saws, give long tool life. For body shops and frame straighteners, custom building and detailing, aftermarket and trailer hitch installations, rustproofers and undercoaters... wherever fast, rugged, and superior quality holes are required... Rotabroach "11,000-Series" Cutters are the single answer. Patented tooth geometry also prevents chip clogging when cutting steel, sheet metal, plastic and wood. Arbors for "11,000-Series" cutters fit 3/8" and 1/2" hand held drill chucks and use a spring loaded pilot guide or skip-proof pilots to eliminate pre-drilling operations.
