Description

The Carmex Vertical Milling CMT Multi Flute Insert - Threading - S170FG55MT8 is a vertical milling indexable insert designed to handle threading, grooves, chamfers, and more. It’s part of the CMT Vertical Mill-Thread family, offering ground-profile inserts for high precision and reliable performance in demanding machining. The system is built for high machining parameters and delivers a smooth, consistent finish, with solid clamping that ensures repeatable results. Chamfer inserts are also available to expand capabilities, and toolholders include a Weldon shank and coolant bore for practical setup and operation.

  • Ground-profile inserts for high precision: Delivers accurate, repeatable threading and milling results with tight tolerances across multiple operations.
  • High-parameter performance with excellent surface finish: Enables faster cutting and better surface quality, reducing secondary finishing work and increasing throughput.
  • Universal threading with robust clamping and versatile toolholders: One insert works for right- or left-hand threads, and is paired with solid clamping and coolant-bore toolholders for reliable, easy setups. Chamfer inserts are available to broaden applications.

This solution helps your shop streamline threading, grooves, and chamfers with consistent quality, improving workflow and reducing setup time. The universal RH/LH capability and strong clamping support quick tool changes, while the integrated coolant bore and Weldon-shank compatibility enhance reliability and production uptime.
