The Carmex Quick Change CAT Polygon Thread Turning Holder is a purpose-built internal threading tool holder designed for CNC lathes. Built for machinists who demand rapid tool changes without sacrificing thread accuracy, it excels in automotive, aerospace, and general manufacturing environments.

• CAT polygon interface: Secure, fast-change compatibility with the CAT toolholder system for minimized downtime.
• Internal threading capability: Optimized for precise internal thread turning across diverse pitch profiles.
• Right-hand orientation: Designed for standard right-handed threading operations in turning centers.
• 70 mm overall length (OAL): Compact, rigid form that fits tight machine envelopes while maintaining stiffness.
• 16IR insert compatibility: Accepts a 16IR insert, enabling a wide range of thread forms and finishes.
• C4 shank size: Sized to integrate smoothly with CAT interface tooling for stable mounting.
• Rugged, precision-minded construction: Engineered to preserve accuracy under high-speed threading conditions.

This holder delivers tangible productivity gains: faster tool changes reduce non-cutting downtime, while its precise internal threading delivers consistent bore threads across profiles, reducing scrap and rework. The combination of a compact 70 mm length, 16IR insert compatibility, and a robust C4 shank makes it a versatile solution for a wide range of threading tasks, from fine pitches to deeper bore threads. Rely on this Carmex holder when you need repeatable, high-quality threads and efficient changeovers in demanding manufacturing environments.
