Its drop-head design delivers enhanced access to tight work areas while keeping the cutting edge firmly aligned for clean, accurate threads.

- 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.
