Carmex Thread Turning Holder Screw Clamp - External - Right Hand - 200mm OAL - 27ER Insert - 40x40 Shank Size

The Carmex Thread Turning External Holder with Screw Clamp is a precision tool holder designed for right-handed external threading on lathes and CNC machines. This right-hand variant offers a robust combination of length, size, and insert compatibility to deliver clean, reliable threads—with a separate left-hand variant available if your setup requires it.

• Right-Hand configuration: Optimized for external threading with right-handed cutting action.
• 200 mm OAL: Provides ample reach for deep or long-threading operations while maintaining rigidity.
• 40x40 shank size: Square shank designed for secure engagement and stability in the tool holder.
• 27ER insert compatibility: Specifically suited for 27ER external threading inserts to achieve precise thread profiles.
• ER and EL insert compatibility: Supports both ER and EL insert types for versatile threading applications.
• U-Type insert accommodation: Specially designed to accommodate U-Type inserts for optimized performance in external threading.
• 1.5° helix angle: Enhances chip evacuation and cutting efficiency for smoother operation and better surface finish.
• Screw Clamp mechanism: Secure, repeatable grip on inserts to reduce runout and improve reliability.
• Robust construction: Built for stability and rigidity during demanding machining tasks.

Designed for machinists who demand consistent, accurate external threads, this holder delivers stable toolholding, repeating results, and improved productivity. The secure screw-clamp design minimizes insert movement, while the combination of 1.5° helix angle and compatible ER/EL/U-Type inserts supports efficient chip flow and extended insert life. Ideal for production threading on CNC lathes and manual machines alike, it helps you achieve precise thread profiles on components such as fittings, fasteners, and hydraulic connectors with fewer adjustments and downtime.
