  • Product Image-Style 294/294A Solid Carbide, Kooltwist®, High Performance, Short Length Drill
  • Dimensional Drawing
Submicron carbide grade provides maximum wear resistance when cutting steels, stainless steels, titanium, high temperature alloys, aluminum, bronze, cast and ductile iron.
  • Coolant feeding S.C. Kooltwist high performance drills yield higher penetration compared to non-coolant fed high performance drills when drilling deep holes.
  • Stub length and 140° double split point eliminate spot drilling and reaming in many instances.
  • High helix, right hand cut.
  • Tool life is increased and peck drilling can be eliminated when used with high pressure coolant.
  • Coating adds lubricity, enhances wear resistance and prevents edge build-up.
    TiN coating is recommended for long chipping, low-carbon, ductile and gummy materials.
    TiAlN coating is recommended for short chipping, abrasive and high temperature materials.
  • Allow 1.5 x Ø of flute for chip exit up to 7/16” (11.1mm) and 1 x Ø over 7/16”.
  • Shank Ø = Cutting Ø
  • Some tool holders and stop screws with a single, central coolant hole may require a coolent groove be added to the shank end of the drill.
