Carmex Vertical Milling CMT Three Flute Insert - Threading - C12I20UNMT7 is a vertical milling indexable insert designed for threading, grooves, and chamfers. With its three-flute design, it is suited for a wide range of users—from engineers and buyers to tradespeople and hobbyists—delivering precise, repeatable results in vertical milling operations.

  • Ground-profile inserts for high precision: Precision-ground profiles deliver consistent threading, grooves, and chamfers with reliable performance in vertical milling applications.
  • High-parameter machining with excellent surface quality: Built to perform at higher machining parameters while maintaining a smooth, high-quality surface finish on workpieces.
  • Reliable clamping and universal threading: Solid, accurate clamping enables full repeatability; the same insert handles right-hand or left-hand threads, and the toolholders include a Weldon shank with a coolant bore. Chamfer inserts are available to expand your capability.

This insert is designed to streamline your workflow by providing precise, repeatable threading and chamfering capability in vertical milling. Its universal RH/LH threading, robust clamping, and coolant-bore toolholders help reduce setup time and integration effort, letting you move from part to part with confidence using the same insert.
