The Carmex Vertical Milling CMT Three Flute Insert - Threading - C18G55MT7 is a versatile vertical milling insert designed for threading, grooves, chamfers, and a variety of precision milling tasks. It’s engineered for a wide range of applications, making it suitable for professionals, technicians, and hobbyists who value reliable performance and consistent results.

Ground profile inserts deliver high precision and excellent performance, even at demanding machining parameters and with superior surface quality. The solid, accurate clamping method ensures full repeatability, and the same insert can be used for right‑hand or left‑hand threads. Toolholders feature a Weldon shank and a coolant bore, and chamfer inserts are also available to expand its capability.

  • Three-flute design for efficient threading: Optimized geometry supports steady cutting and effective chip control, helping you complete threaded operations quickly with consistent results.
  • Ground profile for precision and surface quality: Precision-ground inserts maintain tight tolerances and deliver smooth finishes, even at higher machining parameters.
  • RH/LH compatibility with secure, repeatable clamping: The same insert handles both right- and left-hand threads with a solid clamping system that ensures repeatable results across setups.

This combination of precision engineering and versatility helps you streamline workflows, reduce rework, and achieve reliable thread quality across a range of materials. With straightforward setup, dependable performance, and compatible toolholders, you can trust the Carmex CMT insert to deliver consistent results in demanding threading, grooving, and chamfering tasks.
