Blair Rotabroach cutters are for precision hole-making in plastics, mild steel, stainless steel, or aluminum up to 1/2 in. thick. They cut clean, burr-free, round holes fast—unlike twist drills that push or hole saws that tear through materials. They're hollow and cut around the edge of the hole without deforming your material or creating jagged edges. Multiple cutting teeth are precision-ground for long tool life. Wherever fast and superior-quality holes are required, a set of Rotabroach cutters is the answer. Patented tooth geometry prevents chip clogging; arbors fit 3/8 in. and 1/2 in. drill chucks and use either
