Depth @ 6 x Ø

Style 293/293A
  • Coolant feeding S.C. Kooltwist® high performance drills yield higher penetration compared to non-coolant fed high performance drills when drilling deep holes.
  • Submicron carbide grade provides maximum wear resistance when cutting steels, stainless steels, titanium, high temperature alloys, aluminum, bronze, cast and ductile iron.
  • 140° double split point provides excellent chip flow over the entire cutting edge.
  • High helix, right hand cut.
  • Tool life is increased and peck drilling can be eliminated when used with high pressure coolant.
  • TiN or TiAlN coating adds lubricity and prevents edge build-up.
  • Larger sizes available see Style 292. Step constructions available up to .713" (18.1 mm).
  • Allow 1.5 x Ø up to 7/16" (11.1 mm) and over 7/16" allow 1 x Ø of flute for chip exit.
