The Carmex Thread Turning Holder (Internal, Right Hand) is a precision tool designed for professionals who demand reliable internal threading performance in CNC lathes and milling setups. With a 250mm overall length, a 32 mm shank, and compatibility with 27IR inserts, it delivers consistent, accurate internal threads in challenging bore geometries.

• Right-Hand Internal Threading Holder: specifically configured for right-handed threading applications to ensure proper chip flow and cutting action.
• 250 mm Overall Length (OAL): extended reach for deep internal threads and hard-to-access bores.
• 32 mm Shank Size: rigid support for enhanced stability during heavy cutting.
• 27IR Insert Compatibility: designed to accept Carmex 27IR inserts for precise threading geometry.
• U-Type Holder Compatibility: engineered to work with U-Type inserts for a secure, precise fit and fast setup.
• 1.5° Helix Angle: optimized for efficient chip evacuation and reduced cutting forces, enabling smoother operation and longer insert life.
• Screw Clamp Tooling: secure clamping mechanism that minimizes runout and improves repeatability over long production runs.

This holder translates into clean, consistent internal threads with tight tolerances across materials, from steel to stainless and certain non-ferrous alloys. The combination of long reach and sturdy shank allows you to access deep bores without sacrificing rigidity. The integrated 1.5° helix angle enhances chip flow, reduces heat buildup, and lowers cutting forces, while the screw-clamp design ensures repeatable results and quick tool changes when paired with compatible inserts. Ideal for precision machining environments where reliable internal threading is essential for accuracy and throughput.
