- Orientation: Left-hand internal threading holder, optimized for LH thread production and consistent chip flow.
- Length: 200 mm overall length (OAL) to reach deeper bore depths without repositioning.
- Shank Size: 25 mm shank to fit standard toolposts and compatible CNC setups.
- Insert Compatibility: Designed to work with 22IL U-Type inserts for precise, secure engagement in internal threads.
- Clamping: Carmex screw clamp mechanism provides reliable, repeatable toolholding with minimal runout.
- Helix Angle: 1.5° helix angle to improve chip evacuation and reduce cutting forces for smoother threading.
This holder delivers a stable, high-precision platform for internal threading operations, helping you achieve accurate thread profiles, cleaner finishes, and longer insert life. Its combination of LH orientation, extended reach, and secure U-Type insert compatibility makes it a practical choice for complex internal threads in aerospace, automotive, hydraulic, and general manufacturing applications.
