Meet the Carmex Vertical Milling CMT Multi Flute Insert for Grooving (SG200FW171MT8) — a vertical milling indexable insert system designed to tackle threads, grooves, chamfers, and more with a single, repeatable insert. Built for engineers, machinists, and hobbyists alike, it pairs ground-profile inserts with rigid toolholders to deliver precise results and high-quality surface finishes at elevated cutting parameters. Chamfer inserts are also available.

• Ground-profile inserts for high precision: Ground profiles provide tight tolerances and superior surface finish, ensuring accurate groove and thread forms even when you push for faster cutting.
• Universal threading insert: The same insert works for both right- and left-hand threads, reducing tool inventory and setup time while maintaining repeatable, reliable results.
• Weldon-shank, coolant-bore toolholders: Offers solid, accurate clamping with integrated coolant delivery to improve heat management and chip control during demanding grooving and threading operations.

This system supports streamlined workflows in vertical milling by combining versatile inserts with rugged, coolant-ready holders. You’ll experience consistent performance, easier changeovers, and high-quality finishes across a variety of grooves, threads, and chamfers—backed by a reliable clamping method that ensures repeatability job after job.
