Carmex Thread Turning Holder Quick Change (CAT) Polygon - Internal - Right Hand - 90mm OAL - 16IR Insert - C4 Shank Size

The Carmex Quick Change CAT Polygon Thread Turning Holder is a precision tool designed for fast, repeatable internal threading on CNC lathes. Right-handed and built for CAT polygon compatibility, it delivers rapid tool changes to keep production lines moving in automotive, aerospace, and general manufacturing settings.

• CAT polygon compatibility: Polygon profile designed for seamless integration with the CAT toolholder system, ensuring secure seating and repeatable threading geometry.
• Internal thread turning capability: Specifically engineered for precise internal threading across common profiles, delivering consistent thread form.
• Right-Hand orientation: Optimized for right-hand threading operations in standard CNC setups.
• 90 mm overall length (OAL): Compact length that fits typical lathe envelopes while maintaining rigidity for accurate cuts.
• 16IR insert: Designed to accept a 16IR insert for clean chip formation and precise thread contours.
• C4 shank size: C4 shank interface ensures compatibility with compatible toolholders and turret systems.
• Quick Change mechanism: Enables rapid tool changes, reducing machine downtime and boosting productivity on threading jobs.

Use cases include high-volume automotive fastener production, precision aerospace components, and precision-milled fittings where consistent thread depth and tight tolerances matter. The holder’s robust construction and precise alignment minimize chatter and thread deviation, helping achieve a reliable fit with minimal rework. By enabling fast swaps between threading tasks, shops can optimize setups, shorten cycle times, and maximize spindle utilization while preserving tool life through controlled cutting geometry.
