Carmex Left-Hand External Thread Turning Holder is a precision tool designed for external threading on a lathe. Built for machinists who need dependable performance with a 150 mm overall length and compatibility with ER/EL inserts, it delivers consistent, accurate threads.

• Left-Hand external thread turning holder: specifically oriented for left-hand threading operations on external threads.
• 150 mm overall length (OAL): long reach provides stability and access to deeper workpieces.
• 25 x 25 mm shank: compact, standard shank size for versatile mounting in toolposts and libraries.
• 22EL insert compatibility: designed to work with ER and EL insert types for a wide range of thread profiles.
• 1.5° helix angle: optimized geometry for efficient chip evacuation and smooth cutting action.
• Top clamp or screw clamp options: flexible clamping method to suit different applications and preferences.
• Top clamp design for secure engagement: ensures stable, precise clamping during threading operations.

This holder helps you achieve clean, accurate external threads with reduced setup time and improved process stability. The secure top-clamp engagement minimizes tool deflection under load, while the option to switch between clamping methods lets you tailor the setup to material, pitch, and cutting conditions. With compatibility for ER/EL inserts, you can select the right insert geometry for the job, minimizing tool wear and maximizing productivity. The 150 mm length and 25x25 mm shank deliver rigidity and reach for challenging parts, making it well-suited for industrial workshops and precision manufacturing environments.
