Carmex Single Long Carbide Shank 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.
  • A line of carbide shank tool holders. These holders were engineered in order to provide an efficient and cost-effective solution for applications that require a long overhang.
  • Features:
  • Internal coolant bore
  • Overall holder length up to 270 mm (metric versions) / 10.5 inch (inch versions)
  • Notes:
  • When machining long overhang jobs, reduce the cutting speed and feed rate between 20-40% (exact value depends on workpiece material, thread pitch, and amount of overhang)
  • SR0390K12C can’t be used with conical inserts: 12-18 NPT / 12-18 NPTF / 12-19 BSPT
