Palbit's Threaded Coupling Holder is a precision tool holder engineered for micro internal threading. For PO0403 inserts (Part No. 181113700), it delivers exceptional rigidity and secure insert retention in compact tooling setups, enabling precise thread cutting and extended tool life.

• Compatibility: Designed for PO0403 inserts, ensuring a secure fit in tight threading applications.
• Diameter: 25 mm cutter diameter for compact, accurate thread profiles.
• Micro internal threading: Specifically engineered to handle fine-detail internal threads with consistency.
• Rigidity: Exceptional rigidity to resist deflection during cutting.
• Insert retention: Secure retention reduces insert movement for repeatable results.
• Vibration reduction: Optimized geometry minimizes vibration and chatter.
• Tool life and finish: Stabilizes cutting engagement to extend tool life and improve surface finish.

By providing a rigid, clamped interface and a dedicated micro-threading design, this holder minimizes runout and vibration, delivering clean, accurate threads with tight tolerances. The compact form fits into small tooling envelopes without sacrificing stability, helping CNC engineers and machinists achieve repeatable results and longer tool life in fine-detail projects.
