The Carmex Thread Turning Holder Through Coolant (Internal, Right-Hand) is a precision tool designed for internal threading on CNC lathes and turning centers. Its thoughtful design combines through-coolant capability with a secure screw-clamp interface, delivering reliable performance in deep bore applications with a 150 mm overall length.

• Through-Coolant Bore: Integrated coolant channel directs cutting fluid straight to the insert, improving cooling, flushing chips, and extending tool life.
• Internal Threading Capability: Engineered for high-precision internal threads with consistent concentricity and surface finish.
• Right-Hand Configuration: Optimized for internal right-hand threading to suit common production requirements.
• 16IR Insert Compatibility: Specifically designed to pair with internal right-hand (IR) inserts for a secure, accurate fit.
• 16 mm Shank: Sturdy 16 mm shank provides rigidity and compatibility with standard tool holders.
• 150 mm Overall Length (OAL): Long reach enables threading in deeper bores without sacrificing stability or accuracy.
• Screw Clamp Interface: Robust clamping keeps the insert firmly in place, reducing tool displacement and improving repeatability.
• Rugged, Precision-Machined Body: Built to endure demanding machining environments while maintaining alignment under load.

This holder translates into tangible benefits: cooler inserts and workpieces, cleaner internal threads, and longer tool life thanks to efficient chip evacuation and cooling. The combination of a secure screw-clamp connection and a through-coolant design minimizes runout and dislocation risks, delivering repeatable, high-quality internal threads in materials used across automotive, aerospace, and hydraulics industries. If you need a reliable internal threading solution with deep reach and precise engagement, this Carmex holder is engineered to perform.
