The Carmex Thread Turning Holder Standard is a precision internal threading tool built for left-hand operations, designed to deliver reliable, repeatable threads in bores and cavities. It’s ideal for shops and production lines that require consistent internal thread quality with a robust, easy-to-maintain holder.

• Application: Internal threading holder for left-hand threads, engineered to deliver accurate and repeatable results in bore threading tasks.
• Length and shank: 300 mm overall length with a 40 mm shank size for solid rigidity and compatibility with standard toolposts.
• Insert compatibility: Designed to work with 22UIL inserts, ensuring optimal engagement and predictable performance.
• Holder type: U-Type compatible design that provides secure, precise fit with corresponding inserts.
• Clamp mechanism: Screw clamp retention for reliable insert seating under cutting forces, reducing insert movement during operation.
• Helix angle: 1.5° helix angle to improve chip evacuation and lower cutting forces, contributing to smoother threading operations.

This thread turning holder combines long reach with rigid support, making it well-suited for deep internal threads where stability and precision matter most. The left-hand configuration supports specialized machining workflows, while the 22UIL insert and U-Type compatibility streamline setup and tool changes. With its screw-clamp retention and optimized chip flow, it helps maintain consistent thread quality from start to finish, even on challenging materials.
