Style 296
  • Submicron carbide tipped coolant fed construction provides maximum wear resistance when cutting alloy steels, tool steels, free machining stainless steels, aluminum casting, bronze, cast iron and some nickel base high temperature alloys.
  • Stub length and self-centering 135° helical point eliminate the need for spot drilling.
  • Body diameter reduced to eliminate galling.
  • TiN coating adds lubricity and prevents edge build-up.
  • Heavy web, slow spiral for maximum feed rates and chip flow.
  • Request intermediate sizes from grind down range.
  • Right hand spiral, right hand cut.
  • Reduced shank diameter. See below.
  • Same style drill available with standard size shanks, see Style 297.
