The Carmex Thread Turning External Holder (Right Hand, 150 mm OAL) is a precision tool holder engineered for reliable external threading on lathes. Designed for machinists who demand consistent thread forms and stable performance, this holder pairs a robust clamping system with versatile insert compatibility to deliver crisp, repeatable results.

• Right-Hand external thread turning holder: optimized for turning external threads with correct handedness to match your lathe setup.
• 150 mm overall length (OAL): extended reach for long-thread applications while maintaining rigidity.
• 25 x 25 mm shank: square shank size for secure seating in standard toolposts and holders.
• 16ER insert compatibility: designed to accept ER-style inserts for accurate external threading profiles.
• ER/EL insert compatibility: supports multiple insert families to cover a range of thread pitches and materials.
• U-Type insert support: accommodates U-Type inserts for precise seating and stable cutting performance.
• 1.5° helix angle: engineered to improve chip evacuation and cutting efficiency, enhancing surface finish.
• Robust screw-clamp mechanism: ensures secure retention and minimal runout during demanding machining operations.
• Durable construction: built to withstand the rigors of production environments while delivering repeatable results.

This tool holder is ideal for manufacturers, job shops, and engineers who thread shafts, studs, or similar external features. The combination of a secure clamp, compatible insert ecosystem, and a thoughtful helix angle translates to smoother cutting, reduced downtime, and higher consistency across parts. Use it with ER/EL inserts and U-Type inserts to tailor your threading profiles to the material and thread pitch you’re producing, all while maintaining alignment and rigidity from setup to finish.
