The Carmex Vertical Milling CMT Multi Flute Insert – Threading is a high-precision, indexable insert system designed for vertical milling applications. It handles a wide range of tasks—from threads and grooves to chamfers and finishing cuts—using a robust multi-flute design that promotes efficient cutting action and reliable chip control.

Built for a broad audience—including engineers, buyers, tradespeople, hobbyists, and DIY enthusiasts—this system emphasizes accuracy, repeatability, and ease of use. Ground-profile inserts deliver consistent performance at high machining parameters with excellent surface finish, while a solid clamping method ensures full repeatability. The same insert works for both right-hand and left-hand threads, and the toolholders feature a Weldon shank and coolant bore. Chamfer inserts are also available to expand capability.

• Ground-profile inserts for high precision: Ground profiles deliver precise, dependable performance for threading, grooves, and chamfers, even at demanding machining conditions and with superior surface quality.
• Rigid, repeatable clamping; RH/LH threading: Solid clamping enables repeatable results, and the same insert can be used for right-hand or left-hand threads for flexible, cost-effective production.
• Toolholders with Weldon shank and coolant bore: Ready-to-use tooling with secure mounting and coolant delivery, plus chamfer inserts available to expand finishing capabilities.

This system helps you complete complex milling tasks more efficiently, delivering consistent results across runs, reducing downtime, and simplifying integration into existing setups. With reliable supporting components—the ground-profile inserts, robust clamping, and coolant-enabled toolholders—you can trust this solution for precise threading, grooves, and chamfering in a wide range of materials and applications.
