The Carmex Thread Turning Holder Standard is a precision internal threading toolhead designed for right-hand operations, built to deliver consistent, repeatable internal threads. Optimized for use with 22IR inserts and a 170 mm overall length, it provides a sturdy 20 mm shank for reliable performance in deep or challenging bores.

• Right-Hand Internal Threading: Configured for right-hand internal threads to suit common machining setups and ensure predictable cutting direction.
• 170 mm Overall Length: Extended reach that enables access to deep or hard-to-reach features without sacrificing rigidity.
• 20 mm Shank Size: Standard shank dimension designed for compatibility with common toolposts and holders.
• 22IR Insert Compatibility: Designed to accept 22IR inserts for precise seating and stable cutting geometry.
• U-Type Insert Ready: Built to work with U-Type inserts, enabling secure, quick insert changes.
• 1.5° Helix Angle: Helix angle optimized to improve chip evacuation and reduce cutting forces for smoother threading operations.
• Screw Clamp Retention: Screw-clamp design provides secure retention of the insert, supporting repeatable accuracy job after job.

In practice, this holder delivers clean, accurate internal threads with dependable repeatability. The 1.5° helix angle aids chip flow, helping to minimize built-up heat and maintain a stable cutting environment. The combination of 170 mm reach, a 20 mm shank, and compatibility with 22IR and U-Type inserts means you can tackle deeper bores and varied internal threading tasks with confidence and efficiency. The screw-clamp retention ensures the insert stays precisely in place, reducing downtime and setup adjustments between operations.
