The Carmex Thread Turning Holder Standard for Internal threading is engineered for precision-focused machinists who routinely create clean internal threads. This right-hand variant delivers reliable performance over a long reach, making it ideal for deep internal features on CNC lathes and manual machines.

• Right-hand internal threading holder: Optimized for clockwise threading operations with consistent engagement and control.
• Overall length: 250 mm (OAL) provides ample reach for deep internal threads while maintaining rigidity.
• Shank size: 32 mm to fit standard tool-holding systems and adapters.
• Insert compatibility: Designed to work with 22IR inserts for precise internal threading geometry.
• U-Type compatibility: Specifically compatible with U-Type inserts to ensure a secure, accurate fit and minimal runout.
• Clamp mechanism: Screw clamp threading bars enable quick, secure insert changes with stable retention during heavy cuts.
• Helix angle: 1.5° helix angle engineered to improve chip evacuation and reduce cutting forces for smoother operation.
• Product line context: Part of Carmex’s internal-threading family, with left-hand and right-hand variants available to match your threading direction.

This holder supports consistent, repeatable internal-threading results, helping you reduce tool deflection and achieve cleaner threads. The long reach combined with a secure screw-clamp system minimizes setup time and downtime, while the 1.5° helix angle enhances chip flow to extend insert life. Ideal for precision work on components like housings, valves, and other assemblies requiring accurate internal threads.
