The Carmex Thread Turning Holder Standard is an internal threading tool designed for right-hand operations, delivering precise, repeatable bore threads with a secure insert clamp. Built for demanding shop use, it combines long reach with rigid, reliable performance.

• Right-Hand internal threading orientation: Optimized for right-handed internal threads to ensure consistent cutting direction and thread quality.
• Internal threading capability: Specifically configured to hold U-Type inserts securely for accurate internal threading results.
• 350 mm overall length (OAL): Extended reach to access deep bores while maintaining controllable tool dynamics.
• 50 mm shank size: Robust interface with standard toolposts, providing stiffness and reduced deflection during machining.
• 16IR insert compatibility: Designed to pair with 16IR inserts for efficient material removal and clean thread profiles.
• U-Type insert compatibility: Ensures a secure, precise fit with corresponding U-Type inserts for dependable performance.
• 1.5° helix angle: Helix angle promotes effective chip evacuation and lowers cutting forces for smoother threading operations.
• Screw clamp design: Securely locks the insert in place to minimize movement and maintain repeatable results between jobs.

This holder is ideal for precision internal threading in automotive components, hydraulic fittings, instrumentation, and other engineered parts requiring reliable internal threads. With its long reach, secure clamping, and compatible insert system, you can achieve consistent thread quality, reduce cycle times, and extend insert life across a range of bore sizes.
