The Carmex Thread Turning Holder Through Coolant is a precision internal threading tool designed for machinists who need clean, accurate threads with efficient cooling. It accepts 22IR inserts and uses a secure screw‑clamp connection to deliver reliable performance in demanding applications.

• Through-Coolant Bore: built‑in coolant passage enhances chip evacuation and cooling, helping maintain insert life and thread quality during internal turning.
• Internal Threading Holder: engineered specifically for internal threading operations, compatible with IR (internal right‑hand) inserts for precise, repeatable results.
• Right‑Hand Configuration: optimized for right‑hand internal threading workflows to fit common manufacturing setups.
• 200 mm Overall Length: generous reach enables access to deeper bores and tight pockets without compromising rigidity.
• 25 mm Shank Size: robust shank geometry designed to integrate with standard Carmex tool holders and tooling systems.
• Screw‑Clamp Insert Retention: secure clamping mechanism minimizes insert movement, reducing tool displacement during cutting for consistent threads.

Designed for demanding internal threading jobs, this holder delivers steady rigidity, efficient cooling, and controlled insert seating to produce high‑quality internal threads. Its through‑coolant design and precise screw‑clamp interface help machinists maximize tool life, improve surface finish, and shorten cycle times in deep or confined bores.
