The Carmex Single Threading Insert Holder is a precision tool that holds carbide threading inserts for external and internal threads on CNC milling machines. Built for quick, repeatable thread milling with helical interpolation, it helps engineers, machinists, and hobbyists achieve faster cycles and consistent results. As part of the Mill-Thread family, it provides a cost-effective path to threading with replaceable inserts and includes an internal coolant bore to keep cutting conditions stable. Note: SR0009H12 can’t be used with conical inserts: 12-18 NPT / 12-18 NPTF / 12-19 BSPT.

• Internal coolant bore: Keeps the cutting zone cool and controlled, reducing thermal stress and helping extend insert life for more consistent threading results.
• Indexable carbide inserts for higher productivity: Multi-tooth carbide inserts enable faster cutting speeds and longer tool life per edge, lowering per-thread costs compared with taps and dies.
• Mill-Thread family compatibility: Designed to pair with a wide range of Mill-Thread carbide inserts for both external and internal threading, delivering easy setup and repeatable, reliable results on CNC mills.

This holder supports a streamlined threading workflow, delivering reliable performance across production and job-shop environments. Its sturdy clamp and modular insert mounting support quick changeovers, helping you finish more parts per shift with consistent thread quality and predictable results.
