The Carmex Vertical Milling CMT Three-Flute Insert for Threading is a versatile vertical milling insert designed to tackle threads, grooves, chamfers, and more with a single, repeatable platform. When paired with compatible toolholders, it delivers reliable threading performance across a range of materials and applications.

Ideal for engineers, machinists, shop floor technicians, and hobbyists who demand precision and repeatability, this system uses ground-profile inserts for high accuracy and excellent surface quality at elevated cutting parameters. Its solid, accurate clamping ensures full repeatability, and the same insert can be used for right-hand or left-hand threads. Toolholders come with a Weldon shank and a coolant bore, and chamfer inserts are also available to extend the same platform into additional tasks.

• Ground-profile precision: Delivers tight tolerances and consistent performance for threads, grooves, and chamfers, supporting high-precision results with a smooth surface finish.
• High-parameter performance: Designed to run at higher speeds and feeds while maintaining excellent surface quality and tool life, boosting productivity.
• RH/LH threading with solid clamping: One insert covers both right- and left-hand threads with a robust clamping method, plus toolholders featuring Weldon shank and coolant bore for quick setup and reliable coolant delivery.

This system helps streamline your workflow by enabling fast setup, reliable repeatability, and versatile capability from threading to chamfering—all with a single, replaceable insert. It’s a reliable choice for consistent results, reduced downtime, and easier integration into existing vertical milling setups.
