The Carmex Vertical Milling CMT Multi Flute Insert - Threading (S169H20UNMT8) is a versatile, indexable insert system designed for vertical milling applications. It’s ideal for engineers, buyers, tradespeople, hobbyists, and non-technical users who need reliable threading, grooves, chamfers, and more from a single setup.

With ground-profile inserts, this system delivers high precision and excellent performance even at demanding cutting parameters. The solid, accurate clamping method ensures full repeatability, and the same insert can be used for both right-hand and left-hand threads. Toolholders include a Weldon shank and coolant bore for integrated coolant delivery, and chamfer inserts are available to expand capabilities.

  • Ground-profile inserts for high precision: Delivers tight tolerances and superior surface finish at higher machining parameters for accurate threads, grooves, and chamfers.
  • Universal threading with repeatable clamping: One insert handles both right- and left-hand threads with a robust clamp, reducing setup time and ensuring consistent results.
  • Toolholders with Weldon shank and coolant bore: Easy integration with standard machines and coolant systems, plus the option to add chamfer inserts for expanded operation.

This integrated vertical milling solution helps you streamline workflows, cut down changeovers, and achieve reliable, repeatable results across a range of features. Built for durability and consistent performance, it supports efficient manufacturing with confidence in every pass.
