The Carmex Quick Change (CAT) Polygon Thread Turning Holder is a precision external tool designed for CNC threading jobs. Built for shops that demand fast, repeatable thread cutting, it leverages a CAT-compatible polygon interface for rapid tool changes and reliable performance.

• CAT polygon interface: Polygon-shaped holder that integrates with standard CAT toolholder systems for fast, reliable tool changes in busy machining environments.
• External, right-hand geometry: Specifically configured for external thread turning in right-hand operations to deliver clean starts and consistent thread form.
• 50 mm Overall Length (OAL): Compact, balanced reach that fits into tight tooling envelopes without sacrificing rigidity.
• 16ER insert compatibility: Accepts 16ER inserts for robust cutting performance and predictable chip control during threading passes.
• C4 shank size: Built to the C4 shank standard, providing secure seating and stable cutting under load.
• Quick Change capability: Designed to enable rapid tool changes, reducing downtime and boosting machine uptime.
• Thread turning versatility: Precision-engineered to produce accurate threads across a wide range of profiles, minimizing rework and improving first-pass yields.

For automotive, aerospace, and general manufacturing environments, this holder delivers tangible productivity gains: faster changeovers, consistent thread quality, and fewer interruptions during high-volume threading work. The polygon geometry and CAT interface contribute to reduced chatter and steadier cuts, while compatibility with 16ER inserts and a rigid C4 shank support dependable performance across diverse thread forms. When precision and efficiency matter, this holder helps you achieve reliable, high-quality threads each run.
