Carmex Vertical Milling CMT Three Flute Insert - Threading - C12I1.0ISOMT7 is a vertical milling indexable insert designed for precise threading, grooves, and chamfers. It’s aimed at engineers, machine shops, tradespeople, and serious hobbyists who need reliable, repeatable results in vertical milling operations.

With a ground profile built for high precision, this insert delivers excellent performance at elevated machining parameters and helps achieve a high-quality surface finish. The solid, accurate clamping enables full repeatability, and the same insert can be used for both right-hand and left-hand threads. Toolholders include a Weldon shank and coolant bore, and chamfer inserts are available to expand your capabilities.

• Ground-profile inserts for precision and surface quality: Meticulously ground geometry provides accurate threading, grooves, and chamfers with consistent results and a high-quality finish.
• One insert for right- or left-hand threads: Simplifies inventory and setup by using a single insert for both thread directions.
• Robust clamping with coolant-ready toolholders: Solid, repeatable clamping complements a Weldon shank and coolant bore, delivering reliable performance and easier coolant management.

This combination supports efficient, repeatable vertical milling operations, helping you maintain tight tolerances, reduce downtime, and improve overall workflow from setup to part finishing.
