The Carmex Internal Thread Turning Holder is a precision toolholder designed for accurate internal threading on CNC lathes and turning centers. Built for right-hand applications, it delivers reliable, consistent threads in demanding machining environments.

• Right-hand internal thread turning design: optimized geometry for controlled entry and stable cutting during internal threading operations.
• 140 mm overall length (OAL): extended reach combined with rigid support for precise thread forming.
• 20 mm shank size: compatible with standard tooling setups while maintaining strong, vibration-damped engagement.
• 16IR insert compatibility: accepts 16IR inserts to cover a wide range of thread profiles and pitches.
• Rigid construction with vibration damping: engineered to minimize chatter, delivering cleaner thread surfaces and longer tool life.
• Versatile threading capability: suitable for multiple internal thread profiles with interchangeable inserts for quick setup changes.

Designed for machinists seeking reliable, repeatable internal threads, this holder reduces setup time and improves surface finish. The combination of a robust build, precise geometry, and broad insert compatibility helps maintain consistent thread quality across production runs, even when faced with challenging materials or tight tolerances.
