Carmex Thread Turning Holder Quick Change (CAT) Polygon - Internal - Right Hand - 90mm OAL - 16IR Insert - C5 Shank Size

Carmex Quick Change (CAT) Polygon Thread Turning Holder is designed for machinists who need fast, reliable internal threading with CAT toolholders. This right-handed holder delivers precise, repeatable threads while minimizing downtime on CNC turning operations.

• CAT polygon compatibility: specifically engineered polygon profile that integrates seamlessly with the CAT quick-change system for rapid tool changes.
• Internal thread turning capability: optimized geometry and insert interface for clean, accurate internal threads across multiple profiles.
• Right-hand orientation: designed for standard right-hand threading operations on CNC lathes and turning centers.
• 90mm overall length (OAL): compact, rigid form that maintains stability during heavy cut cycles.
• 16IR insert interface: accepts 16IR carbide inserts to produce consistent thread quality and finish.
• C5 shank size: compatible with common CAT toolholders and fixture setups for secure mounting.
• Precision-engineered body: tightly machined components ensure concentricity and long-term durability in demanding environments.

This holder reduces setup and tool-change time by leveraging Carmex's Quick Change concept, helping machinists boost throughput without compromising thread accuracy. The polygon CAT interface keeps alignment repeatable from setup to setup, so every job—whether automotive fasteners or aerospace fittings—delivers consistent thread profiles. The 90mm length and solid construction minimize vibration and chatter, extending tool life and reducing scrap in high-volume production. With the 16IR insert system, you can select high-quality carbide inserts for various thread pitches, enabling precise threads on shafts, housings, and fittings with fewer passes.
