Carmex Thread Turning External Holder with Screw Clamp is a precise left-hand toolholding solution designed for external thread turning on lathes and CNC machines. It’s engineered to securely accept 11EL inserts, delivering stable, accurate threading performance.

• Left-Hand Design: Optimized for left-handed external threading applications to match specific machining setups.
• 100 mm Overall Length (OAL): Provides the reach and rigidity needed for consistent cutting geometry in tight or long-turning jobs.
• 10 x 10 mm Shank Size: Standard square shank for secure seating in compatible tool holders and fixtures.
• Screw Clamp Mechanism: Robust clamping that minimizes runout and allows reliable insert changes.
• 11EL Insert Compatibility: Specifically designed to securely hold 11EL inserts for external thread turning.
• ER/EL Insert Compatibility: Flexible support for ER and EL insert styles, enabling versatile threading options.
• U-Type Insert Support: Precisely engineered to accommodate U-Type inserts for enhanced alignment and performance.
• 1.5° Helix Angle: Features a gentle helix angle to aid chip evacuation and improve cutting efficiency.
• Robust Construction & Rigidity: Built to withstand demanding turning operations with stable, vibration-free performance.

This holder delivers tangible benefits in real-world threading tasks: sharper, more consistent thread profiles, reduced deflection under load, easier insert indexing and changes, and smoother chip flow even at higher feed rates. It’s well-suited for machinists who need reliable left-hand external threading tooling that works seamlessly with common Carmex inserts and standard 10x10 shank setups, helping you finish parts to spec with less downtime and greater confidence.
