Carmex Thread Turning Holder Quick Change (CAT) Polygon - Internal - Right Hand - 60mm OAL - 16IR Insert - C4 Shank Size

Engineered for precision threading in CNC environments, the Carmex Thread Turning Holder Quick Change (CAT) Polygon delivers fast, reliable internal thread turning with CAT-compatible tooling. It's designed for machinists who demand repeatable thread quality and minimal setup downtime across automotive, aerospace, and general manufacturing applications.

• CAT Polygon Compatibility: Fits the CAT toolholder system for seamless integration and rapid tool changes without removing the holder from the spindle.
• Internal Thread Turning: Specifically optimized for internal thread profiles, delivering accurate, consistent threads in bores, housings, and fittings.
• Right-Hand Configuration: Optimized for right-hand threading operations to match common production requirements.
• 60 mm Overall Length (OAL): Compact reach provides stable engagement in tight cavities while maintaining balance in the cut.
• 16IR Insert Compatibility: Designed to accept 16IR inserts for efficient, repeatable thread forming and finishing.
• C4 Shank Size: C4 shank interface ensures secure seating and reliable transfer of cutting forces in CAT setups.
• Quick Change Design: Time-saving tool-change capability reduces non-cutting downtime and accelerates workflow on busy machining cells.

This holder is a versatile solution for throughput-focused shops that machine a variety of threaded components—from automotive fasteners to aerospace fasteners and precision hydraulic fittings. The polygon geometry combined with CAT compatibility provides stable cutting, improved chip evacuation, and consistent thread depth and pitch across profiles, helping machinists achieve repeatable results part after part. Use cases include internal thread milling in housings, threaded bores for connectors, and any application requiring reliable, repeatable internal threads with minimal setup effort.
