The Carmex Vertical Milling CMT Three Flute Insert for Groove Milling is a ground-profile, indexable insert designed for vertical milling tasks. It pairs with dedicated toolholders to tackle a wide range of operations — from threads and grooves to chamfers — giving shops a single, versatile solution for multiple milling needs. This system is built for engineers, machinists, and hobbyists alike who value precise, repeatable results in a compact setup.

Ground-profile inserts provide high precision and excellent performance, even under demanding cutting conditions. They are designed to work at high machining parameters while delivering a high-quality surface finish. The clamping method is solid and accurate, enabling full repeatability across production runs. An added advantage is that the same insert can be used for both right-hand and left-hand threads, simplifying inventory. Toolholders come with a Weldon shank and a coolant bore, and chamfer inserts are available to complete groove milling applications.

• Ground-profile inserts for high precision: Delivers consistent geometry and repeatable results in threads, grooves, and chamfers, reducing rework and improving part quality.
• Ready for high-parameter milling: Optimized for aggressive feeds and speeds while maintaining excellent surface finishes and reliable performance.
• Versatile threading with repeatable clamping: One insert handles both right- and left-hand threads; compatible toolholders with Weldon shank and coolant bore; chamfer inserts available to extend capability.

This milling solution supports efficient workflows by combining precision, durability, and flexibility in one compact package. It helps you finish jobs faster with fewer adjustments, improves consistency across parts, and provides a dependable foundation for groove, thread, and chamfer milling tasks.
