Carmex Thread Turning Holder Standard - Internal - Left Hand - 300mm OAL - 16IL Insert - 40 Shank Size

The Carmex Thread Turning Holder Standard for Internal Threading is built for shops that demand dependable, precise internal threads from a left-hand approach. With a 300 mm overall length and compatibility with U-Type inserts, this holder delivers consistency across challenging internal threading jobs.

• Left-Hand Internal Threading: Specifically configured for left-hand internal thread production to match your machining setup and threading requirements.
• 300 mm Overall Length (OAL): Long reach that helps access deep cavities and through-holes while maintaining rigidity.
• 40 Shank Size: Robust shank diameter designed for stable clamping on standard tool posts and holders.
• 16IL Insert Compatibility: Engineered to accept the 16IL insert family for reliable wear and consistent thread geometry.
• U-Type Holder Compatibility: Designed to pair with U-Type inserts for secure, precise fit and repeatable performance.
• 1.5° Helix Angle: Helix angle optimized for efficient chip evacuation and reduced cutting forces during threading.
• Screw Clamp Design: Secure, quick-clamp mechanism that minimizes insert movement during cutting.

With this Carmex Thread Turning Holder, you can achieve clean, accurate internal threads in through-holes and blind openings, even in materials that generate difficult chips. The long reach and rigid interface help maintain straight, true threading, while the 1.5° helix angle improves chip evacuation for smoother operation and cooler tools. The left-handed configuration and U-Type insert compatibility give you flexible options for complex projects, reducing setup time and increasing throughput in production environments. This holder is ideal for machinists who value repeatability and efficiency in internal threading tasks, from aerospace and automotive components to precision assemblies.
