Carmex Vertical Milling CMT Three-Flute Insert for Threading is a versatile vertical milling indexable insert system designed to handle threading, grooves, chamfers and more. It’s ideal for engineers, shop floor technicians, and hobbyists who need reliable, repeatable results with a clean, high-quality finish. The ground-profile inserts deliver exceptional precision and surface quality at demanding cutting parameters, while a solid, accurate clamping method ensures full repeatability. The same insert works for right- or left-hand threads, and the toolholders include a Weldon shank with coolant bore; chamfer inserts are also available to expand capabilities.

  • Ground profile inserts for high precision: Tight tolerances and consistent thread geometry deliver repeatable, high-quality finishes even at higher speeds and feeds.
  • Solid, accurate clamping for full repeatability: Robust seating minimizes runout and ensures reliable results across multiple parts and setups.
  • Universal threading capability: The same insert supports both right- and left-hand threads, with toolholders featuring Weldon shank and coolant bore for secure mounting and effective cooling.

This system helps streamline workflows by delivering precise thread milling and chamfering with dependable results, reducing setup time and downtime between jobs. The combination of ground inserts, reliable clamping, and universal threading capability makes it well-suited for a broad range of applications—from production runs to custom projects—so you can finish parts confidently and efficiently.
