The Carmex Thread Turning Holder Standard is a precise internal-threading solution designed for machinists who demand reliable, right-hand threading performance on small to mid-size workpieces.

• Orientation: Right-hand internal threading holder for secure, accurate internal threads.
• Overall Length: 200 mm true overall length (OAL) to reach deep bore applications with stability.
• Shank Size: 25 mm shank for solid grip and compatibility with standard toolposts and turrets.
• Insert Compatibility: Designed to accept 16IR inserts for consistent cutting geometry and performance.
• U-Type Compatibility: Engineered to work with U-Type inserts, delivering a secure, precise fit in the holder.
• Helix Angle: Typical 1.5° helix angle to optimize chip evacuation and reduce cutting forces for smoother threading.
• Clamp Design: Screw-clamp construction provides rigid clamping of the insert and stable engagement during heavy threading.

This holder is ideal for engineers and machinists performing internal Thread turning in lathes or CNC machines, offering dependable guidance and consistent threads in bores where precision matters. The combination of a long reach (200 mm OAL), a robust 25 mm shank, and the 16IR insert compatibility supports a wide range of internal threading tasks, from fine pitch to larger diameter threads, with reduced cutting resistance and improved chip control. The U-Type compatibility further extends its versatility, ensuring a secure fit with compatible inserts for repeatable results across production runs.
