The Carmex Vertical Milling CMT Three Flute Insert - Threading - C12I3.0ISOMT7 is a vertical milling indexable insert designed to handle threading, grooves, chamfers, and other precise milling tasks. As part of the CMT Vertical Mill-Thread family, these ground-profile inserts deliver high precision, excellent performance, and a high-quality surface finish, even when operated at demanding machining parameters.

  • Ground profile inserts for high precision and excellent performance: Precise, ground profiles ensure consistent thread forms and grooves with a smooth surface finish, enabling reliable results across a range of threading and chamfer operations.
  • One insert for right- or left-hand threads: Simplifies procurement and setup by using a single insert for both thread directions, reducing downtime and inventory complexity.
  • Solid clamping with Weldon shank and coolant bore (Chamfer inserts available): Solid, accurate clamping enables full repeatability, while toolholders with Weldon shank and a coolant bore support longer tool life and better chip control; chamfer inserts are available to expand versatility.

This solution helps engineers, machinists, and shops streamline threading and chamfering workflows with a reliable, repeatable insert that performs well at higher machining parameters. By combining precision inserts, a universal thread direction option, and practical toolholding features, it supports consistent results, faster setup, and clearer process planning.
