Description

The Carmex Drop Head Thread Turning Holder is a precision tool for external threading on lathes, built for professional workshops that demand reliability and consistent thread forms. Its drop-head design delivers enhanced access to tight work areas while keeping the cutting edge firmly aligned for clean, accurate threads.

  • Drop-head design: The drop-head geometry positions the insert at the optimal height and angle for external thread turning, improving accessibility and chip control.
  • External thread turning application: Specifically optimized for external threading tasks, providing a dedicated interface for stable, repeatable thread profiles.
  • Right-hand configuration: Designed for standard right-hand threads and conventional turning direction, ensuring compatibility with common machining setups.
  • Overall length: 150 mm (OAL) offers sufficient reach to handle long workpieces without sacrificing rigidity.
  • Insert compatibility: Uses 16ER inserts for precise, repeatable threading geometry and easy insert changes to match thread requirements.
  • Shank size: 25 x 25 mm square shank provides a robust, secure mounting in tool posts and holders.
  • Construction: Built for durability with a precision-machined body to withstand demanding threading tasks and maintain accurate alignment over time.

The result is a dependable threading solution that helps you achieve crisp external threads, minimize rework, and keep production moving. The 150 mm reach expands your capabilities on longer shafts while the 25 x 25 mm shank maintains rigidity under heavy cutting forces. With 16ER inserts, you can tailor thread pitches and diameters quickly, reducing setup time and improving overall throughput in your shop.
