Carmex Thread Turning Holder Through Coolant - Internal - Left Hand - 200mm OAL - 22IL Insert - 25 Shank Size

The Carmex Thread Turning Holder Through Coolant is a precision internal threading solution built for left‑hand operations. Designed for machinists who demand dependable performance in through‑coolant environments, it delivers clean, accurate internal threads with consistent surface finish.

• Through coolant design: integrated coolant bore ensures efficient chip evacuation and enhanced cooling during internal threading, helping maintain tool life and consistent results.
• Internal threading holder: optimized for internal threads with left‑hand threading applications, providing reliable alignment and rigid support.
• Compatibility: engineered to work with IL (internal left‑hand) inserts and IR (internal right‑hand) inserts for flexible threading tasks.
• Dimensions: 200 mm overall length (OAL) with a 25 mm shank size, offering a balanced balance of reach and rigidity for demanding cavities.
• Secure clamping: screw clamp mechanism ensures a secure, vibration‑resistant connection between the holder and the insert, reducing the risk of tool displacement.
• Robust construction: built to withstand the rigors of high‑temperature threading operations while maintaining precision and repeatability.

This holder is ideal for manufacturing and prototyping environments where precise internal threads are required in challenging materials. The through‑coolant feature, combined with a secure screw‑clamp interface and compatibility with IL/IR inserts, supports reliable tool life, reduced cycle times, and higher quality thread finishes across a range of applications.
