Description

Carmex Internal Thread Turning Holder, Right-Hand, is a precision tool holder engineered for professional machining tasks that require accurate internal threading. With a 350 mm overall length and a 50 shank size, it delivers dependable reach and rigidity for deep or dense internal threads.

  • Configuration: Right-Hand internal threading holder designed for reliable internal thread production in a range of materials.
  • Length and shank: 350 mm overall length (OAL) with a 50 shank size for compatibility with standard tool systems.
  • Insert compatibility: Optimized for 22IR inserts to provide secure seating and consistent cutting performance.
  • Retention method: Screw clamp design to hold inserts firmly in place for reliable operation and quick changes.
  • Mounting compatibility: Built to work with U-Type inserts, offering flexibility without sacrificing stability.
  • Helix angle: 1.5° helix angle to improve chip evacuation and reduce cutting forces during threading passes.
  • Construction focus: Precision-engineered for stable performance, smooth engagement, and durable long-term use in production environments.

This holder is ideal for machinists and contract manufacturers performing internal thread milling and threading tasks in molds, housings, and precision assemblies. The combination of long reach, secure insert retention, and a small helix angle translates to cleaner threads, smoother tool action, and extended insert life. Use cases include deep internal threads, finishing passes on challenging materials, and setups where a reliable internal threading solution with quick insert changes is essential.
