HSS & Cobalt Steel
Specifications: Standard 3/4" Shank with flats at 90°. These Annular (Hole) Cutters are made of sturdy M-2 or Cobalt steel. They enable you to cut a burr-free hole. It penetrates rapidly, cutting only the periphery of the hole thus allowing the pilot pin to eject the center plug of steel. Cutters are interchangeable with other standard hole cutting systems.
