The Carmex Quick Change CAT Polygon Thread Turning Holder is a purpose-built toolholder for CNC lathes, engineered to deliver fast, repeatable internal thread turning with reliable CAT-style tool changes.
- CAT Polygon Quick-Change interface: A polygon-shaped design that mates with CAT toolholder systems for rapid, secure tool changes and minimal downtime.
- Internal thread turning capability: Specifically built to produce accurate threads inside bores and threaded holes across a range of profiles.
- Right-hand configuration: Optimized for standard right-hand threading operations in common machining setups.
- 70 mm overall length (OAL): Compact form that fits tight spaces on the turret or in crowded tooling magazines while preserving rigidity.
- 16IR insert compatibility: Accepts standard 16IR inserts, ensuring consistent seating and reliable cutting performance.
- C5 shank size: Designed to fit CAT-compatible spindles with the C5 shank specification for secure clamping and stability.
- Durable, precision-ground body: Built from high-strength tooling material with tight tolerances to maintain thread pitch accuracy over multiple passes.
- Versatile threading companion: Suitable for a wide range of threading applications in automotive, aerospace, and general manufacturing environments.
This holder helps machinists achieve precise thread quality while cutting setup and changeovers dramatically shorter. By combining a CAT polygon quick-change interface with a dedicated internal threading design, it minimizes downtime, stabilizes cutting forces, and supports consistent thread profiles across production runs. Ideal for shops that demand reliable, repeatable results in high-mix, high-volume threading tasks.
