The Carmex Vertical Milling CMT Three-Flute Insert for Threading is an indexable cutting insert designed for vertical milling, enabling threads, grooves, and chamfers with precision.

Built for engineers, buyers, tradespeople, and hobbyists, this solution emphasizes high-precision threading and reliable performance. Ground-profile inserts in the CMT Vertical Mill-Thread line deliver excellent results at higher machining parameters and a smooth surface finish, while a solid, accurate clamping method ensures full repeatability. The same insert handles both right-hand and left-hand threads, and the toolholders include a weldon shank and coolant bore; chamfer inserts are also available.

• Ground-profile inserts for high precision: Precise, ground profiles ensure consistent form and tight tolerances for threading and grooves, delivering reliable results even at higher speeds and loads.
• Solid, repeatable clamping: The robust clamping method provides accurate repeatability across cycles, helping reduce rework and keep production moving smoothly.
• RH/LH threading compatibility with ready-to-use tooling: The insert works for both right- and left-hand threads, and toolholders include weldon shank and coolant bore, with chamfer inserts available to simplify setup and workflow.

By combining ground-profile precision, repeatable clamping, and universal threading capability, this insert helps you achieve consistent thread quality and reliable performance in vertical milling applications. The weldon-shank toolholders with coolant bore streamline integration, and chamfer inserts extend your capability without adding extra tooling.
