Description

The Carmex SG170FW20MT8 Vertical Milling CMT Multi Flute Insert for Grooving is a precision indexable insert system paired with robust toolholders designed for threads, grooves, chamfers, and other milling tasks. Built for engineers, machinists, and hobbyists alike, it delivers repeatable accuracy and high-quality finishes even under demanding cutting conditions. Chamfer inserts are also available to expand finishing options.

  • Ground-profile inserts for precision and surface quality: The carefully ground geometry delivers tight tolerances and smooth surfaces, maintaining excellent performance at higher cutting parameters for consistent results across jobs.
  • Universal right- and left-hand threading with one insert: Use a single insert for both thread directions, reducing inventory needs and setup time so you can move between parts faster.
  • Weldon shank toolholders with coolant bore: Rugged, accurate mounting combined with integrated coolant delivery improves heat management, extends insert life, and simplifies integration into existing setups.

This system helps you streamline setups, reduce tool changes, and achieve repeatable results across demanding grooves, threads, and chamfers. With precision ground profiles, universal threading capability, and durable, coolant-ready toolholders, you can push cutting parameters confidently while maintaining high surface quality and reliable performance across a range of projects.
