The Carmex Thread Turning External Holder (Left-Hand) is engineered for precise external threading in CNC lathes and turning centers. With a 150 mm overall length and a 25x25 mm shank, this holder delivers rigid support and repeatable thread forms when paired with a 33UEL insert.

• Left-Hand external threading: Specifically designed for turning left-hand external threads with reliable performance.
• 150 mm OAL: Provides adequate reach for longer thread profiles while maintaining rigidity.
• 25 × 25 mm shank: Standardized, secure mounting size for stable toolholding.
• 33UEL insert compatibility: Optimized interface for secure grip and precise cutting with 33UEL inserts.
• ER/EL insert compatibility: Supports common ER and EL inserts for versatile threading options.
• U-Type insert support: Designed to accommodate U-Type inserts for specialized applications.
• 1.5° helix angle: Promotes efficient chip evacuation and smoother cutting in external threading.
• Screw clamp design: Robust clamping mechanism ensures stability and repeatable results during machining.

This holder delivers consistent, high-precision external threading with a secure, repeatable grip. Its rugged construction and 1.5° helix angle support stable cutting and efficient chip removal, helping you achieve clean, accurate threads with fewer passes. The broad insert compatibility reduces tool changes, enabling faster setups and higher productivity for production runs and precision work alike.
