Introducing the Carmex Vertical Milling CMT Three Flute Insert - Threading (C25I5.5ISOMT7). This vertical milling indexable insert system is designed for families of tasks including threading, grooves, and chamfers, making it a versatile choice for engineers, machinists, tradespeople, hobbyists, and shop floor operators who value precision and efficiency.

Built around a ground-profile insert, it delivers high precision and excellent surface quality, even when pushed to demanding cutting conditions. The solid, accurate clamping ensures full repeatability across multiple parts, and the same insert can be used for both right-hand and left-hand threads. The system also supports practical integration with Weldon shank toolholders and coolant bore, and chamfer inserts are available if you need to complete finishing steps in one system.

• Versatile threading, grooving, and chamfering: A single vertical milling insert system handles a wide range of operations, reducing tool changes and streamlining setups for quicker, more efficient production.
• Ground-profile inserts for precision and surface quality: Ground profiles provide high accuracy and a smooth finish, delivering reliable performance even at higher cutting parameters.
• Bidirectional threading with rigid, repeatable clamping: The insert works for both right- and left-hand threads and features a solid clamping method that supports repeatable results across runs.

In practice, this setup helps you simplify tooling, shorten cycle times, and achieve consistent thread and chamfer quality across diverse materials. With welded-shank toolholders and an integrated coolant bore, it’s ready to fit into established workflows, reducing downtime and helping you maintain tight tolerances with confidence.
