The Carmex Single Threading Insert Holder is a precision tool holder designed for carbide external and internal threading inserts. It is part of the Mill-Thread family and is built to enable threading on CNC milling machines using helical interpolation, delivering accurate threads with increased productivity.

• Internal coolant bore: Helps manage cutting temperatures and maintain insert life for consistent thread quality during demanding milling work.
• Mill-Thread compatible design: Specifically engineered to hold Mill-Thread carbide inserts, enabling quick setup and reliable threading on CNC mills.
• Cost-effective replaceable inserts: Reduces tooling costs by allowing use of affordable, replaceable carbide inserts instead of single-use taps and dies, with less downtime when changes are needed.

Using this holder, you can streamline threaded features across a wide range of parts—from fasteners to housings—by swapping worn inserts rather than entire tools. The internal coolant path helps sustain performance during high-speed milling, while the sturdy, carbide-ready construction resists wear in busy production environments. The result is consistent thread quality, shorter cycle times, and lower overall tooling costs, helping your CNC mills stay productive and cost-efficient.
