The Carmex Thread Turning Holder Through Coolant is a precision internal threading bar built for machinists who demand reliable performance in deep or restricted cavities. Designed to work with internal right-hand (IR) and left-hand (IL) inserts, this holder delivers consistent, high-quality threads with through-coolant efficiency.

• Tool Type: Screw Clamp Threading Bar with through-coolant capability for effective chip evacuation and edge cooling during internal threading.
• Compatibility: Supports internal right-hand (IR) and internal left-hand (IL) inserts, enabling both R and L threading applications in a single holder.
• Insert Fit: Optimized for 16IR inserts, ensuring a secure, precise interface between bar and insert.
• Shank Size: 32 mm shank for strong, stable engagement and reduced tool deflection during cutting.
• Overall Length: 250 mm (OAL) to reach deep internal threads and hard-to-access features.
• Clamp Mechanism: Robust screw clamp provides a secure, repeatable connection that minimizes insert movement and chatter.
• Coolant Through: Built-in coolant bore supports through-coolant delivery, improving chip evacuation and cooling at the cutting edge.

Equipped for demanding internal threading tasks, this holder helps you achieve cleaner threads, longer insert life, and more consistent performance across a range of materials. The combination of through-coolant efficiency, a secure screw-clamp interface, and compatibility with IR/IL inserts makes it a versatile choice for both routine and precision internal threading operations in production or repair environments.
