The Carmex Thread Turning Holder Standard – Internal, Right-Hand is built for machinists who demand precise internal threading in deep bores. With a long reach and a robust shank, it delivers repeatable thread forms and smooth operation in demanding environments.

• Right-hand internal threading holder: Specifically configured for right-hand threading operations to provide consistent engagement and thread form.
• Overall length: 300 mm (OAL) to reach deep workpieces and long-spindle applications with ease.
• Insert compatibility: Designed to accept a 27IR insert for accurate internal thread generation and reliable surface finish.
• Shank size: 40 shank size, compatible with standard tooling and mounting systems.
• U-Type compatibility: Built to pair with U-Type inserts for secure seating and precise alignment.
• Helix angle: 1.5° helix angle that promotes efficient chip evacuation and lowers cutting forces during threading.

This holder is ideal for shop floors and job sites where deep internal threads must be produced cleanly and consistently. The combination of a long 300 mm reach, a sturdy 40 shank, and the 27IR insert capability makes it a reliable choice for automotive, hydraulic, and general manufacturing applications that require high-precision internal threads with minimal tool deflection and excellent finish each cycle.
