The Carmex Vertical Milling CMT Three Flute Insert for Threading is a versatile vertical milling indexable insert system designed to handle threads, grooves, chamfers and more with a single, reliable tool. It’s ideal for engineers, machinists, buyers, tradespeople, hobbyists, and shop floor teams who need precise, repeatable results in a compact setup.

Built around ground-profile inserts, this system delivers high precision and excellent performance even at demanding machining parameters. It uses a solid, accurate clamping method to ensure full repeatability, and the same insert works for both right-hand and left-hand threads. Toolholders come with a Weldon shank and coolant bore, and chamfer inserts are available to expand capabilities.

  • Ground-profile inserts for high precision: Delivers consistent accuracy and a superior surface finish, enabling reliable threading and milling at higher speeds and feeds.
  • One insert for right- or left-hand threads: Simplifies your toolkit by eliminating the need for separate left/right inserts, reducing setup time and inventory.
  • Weldon shank with coolant bore in toolholders: Ensures secure mounting, easy setup, and effective cooling for longer tool life and cleaner chips.

This setup helps you streamline milling workflows, improve repeatability across parts, and achieve dependable results in demanding threading and chamfering applications without constant tool changes.
