Thread Mills

Greenfield Industries High Performance Thread MillsWidia GTD (formerly Greenfield) thread mills achieve greater precision and higher speeds, opening up a whole new range of threading production options. One tool cuts both right and left hand threads in internal and external applications. You can operate at up to 40% higher feed rates and still expect up to 50% longer tool life. When using indexable thread mills, tooling and inventory costs are significantly reduced. All of which can add up to productivity increases as high as 500%.

Consider thread milling when:
  • Taper pipe threads are being produced.
  • The material is difficult to machine (e.g. high temperature alloys and heat treated materials up to 62 Rc).
  • The machine has helical interpolation and RPM greater than 6,000.
  • Thread specifications require special taps.
  • Usable threads are required to within 1 pitch of the bottom of the hole or counterbore.
