The Carmex Thread Turning Holder Through Coolant is a precision internal threading tool designed for machinists who demand reliable, repeatable internal threads. Built for versatility, it supports both right-hand (IR) and left-hand (IL) threading when paired with the respective inserts, and it leverages through-coolant cooling to maintain cutting performance.

• Thread direction versatility: Internal threading capability for both right-hand (IR) and left-hand (IL) operations, accommodating a wide range of bore-threading tasks.
• Through coolant bore: Integrated coolant passage enhances chip evacuation and cooling, helping to control heat and extend insert life during long or deep cuts.
• Screw clamp insert retention: Robust screw-clamp mechanism securely mounts IL/IR inserts, reducing tool movement and improving cutting stability.
• Dimensional spec: 150 mm overall length (OAL) with a 16 shank size, designed for stable engagement in deep internal threading applications.
• Insert compatibility: Engineered to work with 16IL inserts and IR equivalents, ensuring a precise, secure fit for consistent thread quality.
• Durable, precise construction: Built to withstand demanding internal threading workloads while maintaining tight tolerances for repeatable results.

In practice, this holder delivers clean, accurate internal threads across a variety of materials, with dependable chip control and insert life thanks to through-coolant cooling. The combination of screw-clamp retention and IR/IL insert compatibility reduces tool displacement during cuts, helping you achieve reliable thread quality and improved productivity in production or precision machining environments. The 150 mm length and 16 shank size provide a stable platform for deep or challenging bore threads, making this Carmex tool an dependable choice for internal threading jobs that require consistency and versatility.
