The Carmex Thread Turning External Holder is designed for precise left-hand external threading, delivering stable performance in demanding machining environments.

With a robust screw-clamp design and broad insert compatibility, it adapts to various threading needs, including ER and EL inserts, as well as U-Type inserts, for versatile external threading applications.

• Configuration: Left-hand external thread turning holder with a secure screw-clamp system for reliable cutting participation.
• Dimensions: 200 mm overall length (OAL) and a 40x40 mm square shank for rigid, stable mounting.
• Insert Compatibility: Accepts 22UEL inserts, with support for ER and EL inserts and U-Type inserts to cover multiple thread profiles.
• Clamping System: Durable screw clamp provides consistent grip and minimizes tool runout during performance.
• Chip Evacuation: 1.5° helix angle promotes efficient chip flow, improving cutting efficiency and reducing heat buildup.
• Construction: Built for rigidity and long-term reliability to maintain precision across extended machining runs.

In practice, this holder delivers predictable, repeatable thread quality on external threads while simplifying setup and tool inventory. The left-hand configuration is ideal for specific threading workflows, and the combination of 200 mm OAL and 40x40 shank delivers solid engagement in tool posts. The screw-clamp design, along with the 1.5° helix angle, supports cleaner cuts, better surface finishes, and longer insert life by aiding chip evacuation and reducing resistance. With support for 22UEL, ER/EL, and U-Type inserts, it provides flexible, ready-to-use options for a range of external threading tasks.
