The Carmex Thread Turning External Holder (Right-Hand, 100 mm OAL) is a precise, robust tool holder designed for external thread turning on lathes and CNC turning centers. Built for reliability, it uses a secure screw-clamp system and is compatible with ER/EL inserts and U-Type configurations, making it a versatile choice for demanding threading jobs.

• Right-Hand external threading: optimized for producing right-hand threads with clean, repeatable results.
• 100 mm overall length: extended reach for better access on larger workpieces and improved rigidity.
• 10x10 mm shank: standard, compatible with a wide range of tool posts and turrets.
• ER and EL insert compatibility: supports common external threading inserts for versatile thread pitches and finishes.
• U-Type insert support: designed to accommodate U-Type inserts for precise alignment and stable cutting.
• 11ER insert optimized: compatible with 11ER geometry to deliver consistent chip formation and surface finish.
• Screw-clamp retention: quick, secure locking that minimizes runout and stabilizes cutting forces.
• 1.5° helix angle: enhances chip evacuation and improves cutting efficiency during longer runs.
• Robust construction: engineered for rigidity and dependable performance under sustained threading operations.

This tool holder is ideal for job shops and manufacturing environments that require accurate external thread turning on a range of parts—from shafts to housings. The combination of a solid screw-clamp mechanism, compatible insert options (ER/EL and U-Type), and a precise 1.5° helix angle helps you achieve consistent thread leads, better surface finish, and shorter cycle times. Use cases include external threading of metric and inch threads on small to medium-sized parts, with reliable repeatability across multiple setups. When selecting inserts, pairing the 11ER geometry with the 100 mm OAL holder ensures stable cutting conditions and predictable performance across common thread pitches.
