  • Helical point increases tool life in medium carbon tool steels, cast iron, and some nickel based materials.
  • TiN coating adds lubricity and prevents edge build-up.
  • Not intended for interrupted cuts.
  • High speed "milled" body runs 2 to 4 times gundrill feeds on conventional equipment.
  • Longer carbide yields increased regrinds and improves drill support.
  • Straight flute, right hand cut.
  • Specials available to 1.375" (35.925 mm) Ø. Request smaller sizes from grind down range.
