The Carmex Vertical Milling CMT Three Flute Insert - Threading (C1814NPTMT7) is a ground-profile, indexable insert designed for vertical milling to accurately create threads, grooves, chamfers and more. Built for precision and repeatability, it excels in demanding production environments where consistent form and surface quality matter.

This tool is ideal for engineers, machinists, fabricators and hobbyists who need dependable threading capability with easy setup. It works with compatible toolholders that feature a Weldon shank and a coolant bore, and the same insert can be used for both right- and left-hand threading.

  • Ground-profile inserts for high precision: Deliver tight tolerances and superior surface finish even at higher cutting parameters, ensuring accurate thread forms and clean grooves.
  • Solid, accurate clamping for repeatable performance: Provides full repeatability from part to part and reduces downtime during tool changes, supporting consistent results.
  • One insert for both thread directions with ready-to-use toolholders: Supports right- or left-hand threads and includes toolholders with Weldon shank and coolant bore for quick setup and reliable coolant delivery.

In use, this insert helps you achieve dependable, repeatable results across a range of threading and contouring tasks. The combination of a ground-profile insert and robust clamping translates to improved part quality, less rework, and faster cycles. With a single insert that handles both thread directions and tooling that supports coolant delivery, you can simplify tooling inventory and reduce setup time—so you can focus on getting parts done right the first time.
