The Carmex Vertical Milling CMT Three Flute Insert - Threading (C12I12UNMT7) is a versatile, indexable insert designed for vertical milling tasks such as threading, grooves, and chamfers. It’s built for a wide range of applications—from production work to prototyping—delivering dependable, repeatable results in a compact, easy-to-use package.

Ground-profile inserts provide high precision and excellent surface quality, even when pushed to higher machining parameters. This enables consistent thread forms and smooth finishes across batches, helping you meet tight tolerances with confidence.

  • Ground-profile inserts for precision threading: Delivers accurate thread forms and superior surface finish at higher cutting parameters for reliable, repeatable results.
  • Same insert for right- or left-hand threads: Simplifies setup and reduces tool inventory, enabling fast direction changes without changing inserts.
  • Rigid clamping with weldon shank and coolant bore: Ensures repeatable tool positioning and efficient coolant delivery, extending insert life and improving chip/mechanical control.

This system is designed to enhance your workflow by providing a complete threading solution for vertical milling. In addition to threading, it supports a range of related operations, with chamfer inserts available to further expand capabilities while maintaining consistent performance and reliability.
