The Carmex Vertical Milling CMT Three Flute Insert - 90° Chamfering (C18C90MT7) is a precision indexable insert built for vertical milling tasks such as threads, grooves, and chamfers. Designed for engineers, machinists, and shops, it delivers accurate 90-degree chamfers and repeatable results with a compact, reliable design.

Its ground profile provides high precision and excellent performance, even when cutting at demanding parameters and delivering a high-quality surface finish. The solid, accurate clamping method enables full repeatability, and the same insert can be used for both right-hand and left-hand threads. The system accommodates toolholders with Weldon shanks and coolant bores, and chamfer inserts are also available for expanded capabilities.

• Ground profile for precision: Ground geometry delivers consistent dimensions for high-precision vertical milling and chamfering, with excellent surface quality at speed.
• One insert for RH and LH threads: The same insert handles both right- and left-hand threads, increasing flexibility and reducing setup time and tool changes, even at high machining parameters.
• Solid clamping with coolant-ready toolholders: The secure, repeatable clamping combined with Weldon-shank and coolant-bore toolholders ensures reliable performance and effective heat management during heavy-duty milling.

This insert provides a reliable, versatile solution for vertical milling applications, helping you complete jobs faster with consistent chamfer and thread quality. Its thoughtful combination of precision geometry, flexible threading capability, and robust tooling compatibility supports efficient setup, reduced downtime, and repeatable results across production runs.
