Designed for precision internal threading, the Carmex Thread Turning Holder Standard – Internal, Right Hand (300 mm OAL) delivers dependable performance for machinists and production environments. It’s engineered to pair with U-Type inserts for a secure, accurate fit and repeatable internal threads.

• Right Hand internal threading configuration: Optimized for clockwise internal threading operations, delivering predictable cut direction and chip flow.
• 300 mm Overall Length (OAL): Extended reach handles deep bores and long-threading operations while preserving rigidity.
• 40 Shank Size: Robust shank enhances rigidity and stability under cutting loads for consistent results.
• 22UIR insert compatibility: Specifically designed to accept 22UIR internal threading inserts for precise, reliable performance.
• U-Type holder compatibility: Built to securely seat U-Type inserts, ensuring accurate alignment and reduced runout.
• 1.5° helix angle: Helix angle improves chip evacuation, lowers cutting forces, and supports smoother threading operations.
• Screw clamp mechanism: Secure insert retention minimizes movement during high-speed or heavy-cut threading tasks.
• Internal threading application: A purpose-built tool holder tailored for producing clean, precise internal threads in a variety of metals.

This holder is ideal for shops performing internal threading in components like housings, fittings, and housings with deep bores. The combination of long reach, secure clamping, and efficient chip evacuation helps maximize tool life and thread quality, making it a reliable choice for both job shops and production environments.
