The Carmex Thread Turning External Holder with screw clamp is engineered for precise external threading on lathes. Designed for left-hand setups and paired with standard ER/EL inserts, it delivers stable, repeatable results in demanding machining environments.

• Left-hand external thread turning holder: optimized for left-handed threading operations to match specific machining workflows.
• 150 mm overall length (OAL): extended reach and rigidity for stable cutting in tight or hard-to-reach areas.
• 10x10 mm square shank: compact, compatible interface with a wide range of tool posts and setups.
• Insert compatibility: ER and EL inserts: versatile support for common external threading inserts to cover a broad set of applications.
• 11EL insert compatibility: specifically designed to accommodate 11EL inserts for external threading needs.
• U-Type insert capability: designed to work with U-Type inserts for optimized performance and accuracy.
• 1.5° helix angle: gentle helix angle promotes efficient chip evacuation and smoother cutting action.
• Robust screw-clamp mechanism: secure, repeatable grip minimizes tool runout and maintains rigidity during heavy cuts.

This holder delivers reliable stability for external thread turning, helping you achieve consistent thread profiles and clean finishes. The combination of ER/EL insert compatibility, the 11EL option, and U-Type support gives you versatile setup choices without swapping tools. The 1.5° helix angle supports effective chip control, reducing heat buildup and wear, while the rigid construction and secure clamping ensure repeatable results across multiple parts. Ideal for precision threading tasks in mechanical, automotive, and hydraulic components where clean, accurate external threads matter.
