Carmex Vertical Milling CMT Three Flute Insert – Groove Milling – C12W08 is a precision vertical milling insert system designed for grooves, threads, chamfers and more. Built for shops and professionals, it pairs a robust three-flute insert with versatile toolholders to deliver consistent, repeatable results in demanding setups.

Engineered for high-precision groove milling, this system uses ground-profile inserts that maintain tight tolerances and smooth surface finish even at elevated cutting parameters. A solid, accurate clamping method ensures full repeatability, while a single insert can handle both right- and left-hand threads, reducing setup time and inventory needs.

  • Ground-profile precision: Delivers high-precision groove and thread forms with excellent surface quality, even under high machining parameters.
  • Reliable clamping and versatility: Solid, accurate clamping ensures full repeatability; the same insert works for right- or left-hand threads to simplify setups.
  • Integrated tooling options: Toolholders include Weldon shank and coolant bore, with chamfer inserts available for streamlined, all-in-one groove and chamfer work.

This combination of precision, flexibility, and practical tooling means faster setups, fewer tool changes, and more consistent results across parts. You can push cutting parameters higher for productivity without sacrificing surface quality, while maintaining tight tolerances on grooves and threads. The Weldon-shank compatibility and coolant capability help keep heat under control and align with your existing machining workflow.
