The Carmex Single Threading Insert Holder SR0029J30 is a precision tool holder designed for carbide external and internal threading inserts. Built for CNC milling machines and using helical interpolation, it delivers fast, accurate thread milling across a wide range of applications.

This holder is part of the Mill-Thread family and features an internal coolant bore to keep the cutting edge cool and promote clean chip evacuation. By using multi-tooth carbide inserts, it achieves higher cutting speeds and longer tool life, helping you complete threading jobs faster while significantly reducing tooling costs compared with traditional taps and dies. Compatibility notes apply for conical inserts and certain insert configurations, so be sure to verify which inserts are suitable for SR0029J30.

• Internal coolant bore for improved cooling: Direct cooling at the cutting edge minimizes heat buildup, extends insert life, and supports consistent performance during high-speed threading.
• Indexable carbide inserts for faster threading: Multi-tooth carbide inserts enable higher cutting speeds, longer life per insert, and reduced downtime between tool changes— boosting productivity.
• Mill-Thread compatible threading tool holder: Specifically designed for CNC milling with helical interpolation, delivering reliable, repeatable thread profiles and lowering per-thread tooling costs compared with taps and dies.

Designed to integrate seamlessly into CNC threading workflows, this holder helps you achieve precise, repeatable threads with less tooling expense and downtime. Its robust design and compatibility with the Mill-Thread insert family support efficient setup, consistent results, and improved overall production performance on threading jobs.
