The Carmex Vertical Milling CMT Three Flute Insert – Groove Milling – C25W50 is a ground-profile, three-flute insert designed for vertical milling tasks, including grooves, threads, and chamfers. Built for high precision and excellent surface finish, it performs reliably even under demanding cutting conditions.

Engineers, shop-floor technicians, and hobbyists will appreciate its versatility and repeatable performance. The ground profile and three-flute geometry help maintain tight tolerances and consistent results across a range of applications, while the CMT Vertical Mill-Thread approach supports high machining parameters with smooth finishes.

• Ground profile for high precision: Precision-ground geometry delivers tight tolerances and excellent surface finish on grooves, threads, and chamfers, even at higher machining parameters.
• RH/LH thread compatibility and groove versatility: Use the same insert for right- or left-handed threads, and tackle grooves and chamfers with confidence—reducing tool changes and inventory while expanding capability.
• Solid, repeatable clamping with coolant-ready toolholders: The robust clamping system provides full repeatability across multiple cycles, while weldon-shank toolholders and coolant bore streamlines setup and coolant delivery for longer tool life and less downtime.

By combining a ground-profile geometry, RH/LH thread capability, and a robust, coolant-ready clamping system, this insert helps you complete complex grooves and threads faster with consistent quality. It supports higher machining parameters without compromising accuracy, reduces downtime from tool changes, and delivers reliable, repeatable results across a wide range of materials and applications.
