Carmex Vertical Milling CMT Three Flute Insert (C18W141) is a precision ground-profile insert designed for vertical milling tasks such as groove milling, threading, and chamfering. Built to perform at higher machining parameters, it delivers consistent accuracy and excellent surface quality across demanding applications.

Used with compatible toolholders, this system provides a solid, repeatable clamp and straightforward setup. The same insert works for right- or left-hand threads, helping you simplify inventory and reduce changeovers. Toolholders include a Weldon shank and a coolant bore for integrated cooling and easier integration into your milling workflow.

• Ground-profile, three-flute design for groove milling: The precise geometry supports accurate grooves and threads with efficient chip evacuation and stable cutting at higher speeds.
• High-precision performance under demanding parameters: Tight tolerances and smooth surface quality reduce rework and deliver reliable results in challenging materials.
• Universal threading with ready-to-use tooling: The insert handles both right- and left-hand threads, and comes with Weldon-shank toolholders and a coolant bore for easy setup and improved life.

This combination of precision geometry, repeatable clamping, and versatile compatibility helps streamline milling workflows, reduce downtime, and achieve consistent groove cuts and threads. It’s a dependable, professional choice for engineers, machinists, and shop floor technicians seeking reliable performance from a single insert family.
