Carmex Twin Threading Insert holders

For Carbide External/Internal Threading Inserts

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.
  • The tool holders that belong to this line of products use two threading inserts, resulting in improved productivity.
  • Features:
  • Internal coolant bore
