Blair 111163 Rotabroach Annular Cutter
Use with Arbor 11122 or 11123, 1/4" depth of cut (D.O.C.).
Blair Rotabroach Annular Cutters cut holes up to 3 times faster and last 10 times longer than traditional twist drills or hole saws! Designed for precision holemaking in sheet metal and frame materials up to 1/2" thick, these cutters produce clean, burr-free, perfectly round holes without deforming the stock or damaging surrounding material.
Ideal for sheet metal fabrication, paintless dent repair (PDR), and rustproofing access holes, the snap-in plugs fit snugly for a professional finish. Custom builders and aftermarket equipment installers rely on these cutters for superior quality holes every time.
Crafted from M2 high-speed steel (H.S.S.) with patented tooth geometry, these precision-ground cutters prevent chip clogging and provide smooth cutting through steel, sheet metal, and plastics. Unlike hole saws and twist drills that push and tear, Rotabroach cutters slice cleanly, ensuring no jagged edges or out-of-round holes—even after hundreds of cuts.
