Same toolholder and insert can produce both RH and LH threads. A single insert & toolholder can produce a given thread on many diameters (External & Internal). Most inserts are double sided, having two cutting edges. Longer tool life thanks to a special multilayer coating process.

Our industry-leading assortment of indexable thread milling tools can be used with a wide range of applications. These tools were created in order to machine threading jobs on CNC milling machines (by using helical interpolation programs). They allow for improved productivity, thanks to the increased cutting speeds, and multi-tooth carbide inserts. Additionally, they can be used to lower tooling costs – as they are considerably cheaper than comparable taps and dies.


  • Each tool holder and insert can be used with right-hand and left-hand machining
  • The “prismatic” shape of the insert tail ensures exact and reliable clamping
  • The thread is produced in a single tool pass
  • Capable of threading to one pitch of a shoulder in a blind hole
  • Longer tool life thanks to to a special multi-layer coating process
  • Since lower machine power is required, a smaller machine can produce larger threads in a single operation – with less idle time, and tool changes
