The Carmex Vertical Milling CMT Three-Flute Insert for Threading (Code: C18I5TRMT7) is a versatile indexable insert designed for vertical milling tasks such as threading, grooves, and chamfers. It’s suitable for engineers, machinists, and hobbyists who want dependable, precise results from a single, adaptable tool.

Its ground profile delivers high precision and an excellent surface finish even at higher machining parameters. A solid, accurate clamping system 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, and chamfer inserts are available to broaden its capabilities.

• Precision-ground profile: Delivers tight tolerances and smooth surface finishes for threading and milling tasks, even at higher speeds.
• Rigid, repeatable clamping: Ensures a stable setup and consistent results across production runs.
• RH/LH threading versatility with coolant-ready holders: The same insert works for right- or left-hand threads, and the Weldon shank with coolant bore simplifies integration into standard toolholders.

This threading insert helps you deliver precise threaded features with consistent results across parts, while enabling higher machining parameters for faster cycles. The integrated coolant bore and Weldon-shank toolholders simplify setup and maintenance, reducing downtime and enabling smoother chip control. With chamfer inserts available, you gain expanded versatility in a single, reliable system that supports a wide range of vertical milling applications.
