The Carmex Vertical Milling CMT Three Flute Insert for Groove Milling (C18W196) is a precision indexable insert system designed for vertical milling tasks. It’s ideal for engineers, machinists, and job shops that regularly run grooves, threads, and chamfers with dependable results.

Built around a ground-profile insert, it delivers tight tolerances and a smooth surface finish even at higher cutting parameters. The robust, accurate clamp provides full repeatability, and the same insert can be used for both right- and left-hand threads. Toolholders with Weldon shank and coolant bore extend versatility, while chamfer inserts are available to broaden applications.

• Ground-profile inserts for high precision: Ground geometry delivers tight tolerances and superior surface finish, maintaining accuracy across heavy feeds and long production runs.
• Solid, repeatable clamping at high parameters: A robust locking system minimizes runout and vibration, enabling consistent results even under aggressive machining conditions.
• RH/LH threading compatibility and versatile tooling: A single insert supports both right- and left-hand threads and works with Weldon-shank toolholders and coolant bore; chamfer inserts are available to expand capability.

Using this insert helps streamline your vertical milling workflow by delivering consistent groove and thread profiles with reduced setup time and tool changes. The ground geometry and secure clamp improve surface finish and part accuracy, while the universal threading capability lowers inventory and downtime. Pair it with compatible toolholders and chamfer inserts to tackle a wide range of parts with confidence.
