Meet the Carmex Quick Change CAT Polygon Thread Turning Holder — a precision toolholder for CAT systems designed to accelerate internal threading on CNC machines. It’s built for machinists who require repeatable, accurate threads with minimal downtime across demanding automotive, aerospace, and manufacturing applications.

• CAT polygon compatibility: Designed to fit the CAT toolholder system with a polygon geometry for fast, secure tool changes on the machine table or turret.
• Internal thread turning: Specifically engineered for internal threading tasks, delivering consistent thread profiles and reliable performance across common pitches.
• 90mm overall length (OAL): Compact and rigid form that provides adequate reach without sacrificing stability during cutting.
• Right-hand orientation: Optimized for right-hand threading operations to match typical CNC setups and tooling workflows.
• 22IR insert compatibility: Accepts 22IR inserts, enabling a range of thread forms and predictable insert wear for extended tooling life.
• C4 shank size: Built with a CAT C4 shank for secure mounting in compatible toolposts and spindles, ensuring robust performance under load.
• Quick Change capability: Carmex Quick Change design allows rapid tool changes, reducing setup time and maximizing productive machining cycles.

This holder is a versatile, time-saving solution for precision threading across multiple profiles. The polygon design supports stable seating in CAT-compatible systems, while the 90mm length and C4 shank balance reach with rigidity. Use it to minimize downtime, improve thread consistency, and streamline threading operations in high-demand environments.
