Carmex Thread Turning Holder Screw Clamp - External - Left Hand - 170mm OAL - 16EL Insert - 32x32 Shank Size

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.
