Carmex Vertical Milling CMT Three-Flute Insert – Threading (C18I16UNMT7) is an indexable insert system designed for vertical milling that handles threading, grooves, chamfers, and more. It’s ideal for engineers, machinists, and workshop professionals who need precise, reliable performance in a compact, versatile package.

• Ground-profile inserts for high precision threading: These inserts are ground to tight tolerances to deliver accurate thread forms and excellent surface quality, even at higher cutting parameters.
• Rigid, repeatable clamping: A solid, accurate clamping method ensures full repeatability across multiple inserts and setups, helping reduce drift and setup time.
• RH/LH threading compatibility with coolant-ready toolholders: The same insert handles right- or left-hand threads, and toolholders include a weldon shank and coolant bore; chamfer inserts are also available to expand capabilities.

This system streamlines your workflow by combining precise threading with versatile support for grooves and chamfers in a single setup. The ground-profile inserts maintain consistency under demanding speeds while the robust clamping keeps tolerances stable through production runs. With universal RH/LH compatibility, coolant-ready toolholders, and available chamfer options, you can stock fewer parts and complete more jobs with confidence—whether in a high-volume shop or a demanding maintenance environment.
