Carmex Vertical Milling CMT Threading inserts and tool holders are designed to tackle a wide range of operations—threads, grooves, chamfers, and more—on vertical milling centers. It's built for engineers, machinists, and technicians who need precise, dependable results in demanding applications.

Key advantages include ground profile inserts for high precision, the ability to operate at high machining parameters with a high-quality surface finish, and a solid, accurate clamping method that enables full repeatability. The same insert can be used for right-hand or left-hand threads, and toolholders come with a Weldon shank and a coolant bore. Chamfer inserts are also available to expand your toolkit.

  • Ground-profile inserts for high precision: Ground profile inserts deliver consistent thread forms and smooth finishes, even under demanding cutting conditions.
  • Solid clamping for repeatable, bidirectional threading: A robust clamping method ensures repeatable results and supports both right-hand and left-hand threads with a single insert.
  • Weldon shank toolholders with coolant bore: Integrated coolant delivery and quick mounting through Weldon shanks simplify setup and help manage chip cooling in daily use.

With this vertical milling threading system, you gain a reliable, adaptable solution that supports consistent results, smoother workflows, and confident job setups. The combination of ground-profile inserts, solid clamping, and Weldon-shank toolholders with a coolant bore makes it easy to tackle threading, grooves, and chamfers across a variety of materials in a single, integrated package.
