Carmex Vertical Milling CMT Three Flute Insert - Threading - C12N55MT7 is a vertical milling insert designed for threading, grooves, and chamfers. Its ground profile delivers high precision and excellent performance, even at higher machining parameters and with a high-quality surface finish. The solid, accurate clamping enables full repeatability, and the same insert can be used for both right-hand and left-hand threads. Toolholders with Weldon shank and coolant bore support easy setup and cooling, and chamfer inserts are available to expand capabilities.

• Ground profile for high precision: Ground profile inserts deliver tight tolerances and consistent performance for threading and grooving tasks, ensuring accurate results on every pass.
• High-parameter machining with excellent surface finish: Designed to perform at elevated speeds and feeds while maintaining a smooth, high-quality surface finish to reduce finishing work.
• RH/LH threading with solid, repeatable clamping: The same insert handles right- or left-hand threads, and a solid clamping method ensures repeatable results. Toolholders with Weldon shank and coolant bore simplify setup and cooling; chamfer inserts are available to expand capabilities.

This insert is engineered to improve throughput and consistency across a range of vertical milling applications. The precision ground profile and robust clamping translate to repeatable results and better surface finishes, while the universal RH/LH compatibility reduces the need for multiple inserts. When paired with Weldon shank toolholders and coolant bore options, setup is straightforward and cooling helps extend insert life, contributing to lower downtime and more reliable production.
