Rotabroach cutters are for precision hole making in sheet metal, frame materials and plate stock up to 1/2 in. thick, whether mild steel, stainless steel or aluminum. These are the same tools as those used by OEMs on assembly lines for access holes and accessory equipment installations. For body shops and frame straighteners, custom building and detailing, aftermarket installations, rustproofers and undercoaters - wherever fast, rugged and superior quality holes are required.
