Rotabroach® Cutters
Rotabroach Annular tools cut clean, burr-free, round holes fast, unlike twist drills that push or hole saws that tear thru materials. Because they're hollow, they cut around the edge of the hole, so less work is required and no deforming of material or jagged edges occur. Multiple cutting teeth are precision ground instead of stamped like hole saws, give long tool life.

Rotabroach Cutters are for precision holemaking in sheet metal, frame materials, and plate stock up to ½" 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 - Rotabroach Cutters are the single answer. Patented tooth geometry also prevents chip clogging when cutting steel, sheet metal, or plastics.

Arbors fit 3/8" and 1/2" hand held drill chucks and use either spring loaded pilots or skip-proof pilots which eliminate pre-drilling operations.
