Carmex Vertical Milling CMT Groove Milling insert (C12W171) is a precision vertical milling solution designed for indexable inserts and corresponding tool holders that tackle a wide range of tasks—from grooves and threads to chamfers. Built for engineers, machinists, and shops that demand reliable, repeatable results, this system delivers consistent performance across materials and applications with straightforward setup and operation.

• Ground profile for precision: Tight tolerances on the insert geometry ensure repeatable cuts and stable performance, reducing part variation and finishing passes.
• High-speed, high-parameter milling: Engineered to thrive at elevated cutting parameters while delivering a smooth surface finish, helping you boost throughput without compromising quality.
• Versatile, reliable tooling: One insert handles both right- and left-hand threads, and the toolholders include a weldon shank with coolant bore; chamfer inserts are available for quick, accurate feature completion.

This system is designed to streamline your workflow: the solid, accurate clamping delivers full repeatability, enabling quick setups and minimal tool changes. With ground-profile inserts built for precision and performance, you can trust it to produce consistent grooves, threads, and chamfers that meet tight tolerances and high-quality standards, time after time.
