The Carmex Screw Clamp Thread Turning External Holder (Left Hand) is built for precise external threading on lathes and CNC machines, delivering reliable rigidity and repeatable results in LH operations.

• Left-hand external thread turning holder: Specifically engineered for left-handed threading applications with correct helix direction for efficient cutting.
• 170 mm overall length (OAL): Extended reach that maintains stiffness and stable engagement during longer threading passes.
• 32 x 32 mm shank: Compact, standardized shank size for versatile mounting in common tool posts and turrets.
• Supports 16EL inserts: Optimized to securely seat 16EL external thread turning inserts for consistent, precise results.
• ER/EL insert compatibility: Broad compatibility with ER and EL inserts, enabling a range of thread profiles and finishes without changing holders.
• U-Type insert compatibility: Designed to accommodate U-Type inserts for enhanced stability and accuracy in external threading.
• 1.5° helix angle: Helix angle tuned for efficient chip evacuation and smoother cutting action, reducing built-up edge and heat buildup.
• Robust screw clamp design: Secure, repeatable seating that minimizes tool deflection and promotes consistent thread quality.
• Rugged construction: Heavy-duty build engineered to withstand demanding machining environments and deliver long tool life.

This LH Carmex holder provides practical, real-world benefits: steadier cuts, fewer reworks, and the flexibility to switch between insert types (16EL, ER/EL, and U-Type) as project needs evolve. Ideal for precision external threading on automotive, mechanical, and general engineering components, it pairs a dependable clamping mechanism with a thoughtful geometry that supports clean chip flow and extended insert life. For shops prioritizing reliability and consistent thread accuracy, this holder is a strategic, long-term investment.
