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.

Submicron carbide grade provides maximum wear resistance when cutting tool steels, titanium, cast aluminum, bronze, cast iron, plastics, and other abrasive materials.

• Coolant feeding S.C. Koolcarb double margin drills provide excellent hole straightness and smoother finish.
• 125° four facet web thinned point starts best into a larger point angle.
• Carbide body increases penetration rate over gundrills for use on machining centers.
• Smaller diameters available to 0.1181” (3.0 mm), larger diameters and step constructions available up to 0.9483” (25.0 mm).
• Straight flute, right hand cut.
• Allow 2.5 x Ø up to 1/4” (6.35mm), 2 x Øup to 7/16” (11.1mm) and over 7/16” allow 1.5 x Ø of flute for chip exit.
