The Carmex Vertical Milling CMT Three Flute Insert - Threading is a vertical milling indexable insert system designed for threading, grooves, chamfers, and a wide range of milling tasks. Built for engineers, machinists, buyers, tradespeople, and hobbyists alike, it delivers precise thread forms and clean finishes with a compact, reliable setup.

Ground-profile inserts are engineered for high precision and excellent surface quality, even when pushing parameters in demanding applications. The solid, accurate clamping method ensures full repeatability across multiple operations, and the design uses the same insert for right-hand or left-hand threads. Toolholders come with a Weldon shank and a coolant bore, and chamfer inserts are available for additional versatility.

  • Ground-profile inserts for high precision: Delivers accurate thread forms and superior surface finishes, even at higher machining parameters.
  • Solid, accurate clamping for full repeatability: Ensures consistent results with stable performance across passes and setups.
  • Universal threading capability with versatile toolholders: One insert works for both right- and left-hand threads; toolholders include Weldon shank and coolant bore, with chamfer inserts available for expanded use.

This vertical milling threading solution helps you complete threads, grooves, and chamfers efficiently with reliable, repeatable results. The combination of ground-profile inserts and robust clamping supports higher productivity and better part quality, while the universal threading capability reduces inventory complexity and downtime when changing thread directions. With the Weldon-shank toolholders and built-in coolant bore, you’ll experience smoother operations and easier maintenance across a range of milling tasks.
