The Carmex Thread Turning External Holder (Left Hand, 170 mm OAL) is a precision tool holder designed for external threading tasks in professional machining environments. Built to work with ER/EL inserts and U-Type inserts, it delivers reliable grip, consistent cutting performance, and robust rigidity for demanding thread turning operations.

• Left-Hand Variant: Optimized for left-handed external threading applications, ensuring correct cutting direction and chip flow.
• Overall Length (OAL): 170 mm, providing ample reach and rigidity for demanding cuts.
• Shank Size: 32 × 32 for compatibility with standard modular tooling systems.
• Insert Compatibility: Supports ER and EL inserts; accommodates U-Type inserts for precise thread geometry.
• Insert Type: 33UEL insert compatibility to achieve proven external thread profiles.
• Helix Angle: 1.5° helix for efficient chip evacuation and smoother cutting action.
• Clamping: Screw clamp external holder delivering secure, repeatable grip on the insert assembly.
• Construction: Robust, rigid design engineered to minimize deflection and maintain accuracy during threading.

With this external thread turning holder, you can expect repeatable, accurate thread profiles, reduced chatter, and longer tool life across external threading operations. The 1.5° helix angle enhances chip flow, while insert compatibility (ER/EL and U-Type) offers flexibility to address a range of thread forms and pitches without tool changes. The left-hand configuration integrates smoothly into standard machining setups, enabling efficient setup and quicker changeovers for high-mix production or batch threading tasks.
