The Carmex Vertical Milling CMT Three Flute Insert - Groove Milling - C25W40 is a ground-profile, indexable cutting insert designed for vertical milling applications such as grooves, threads, and chamfers. It works with compatible toolholders to deliver precise, repeatable results in demanding milling tasks.

With a single insert capable of right- or left-hand threading and a solid clamping method, this solution supports high-speed machining and consistent surface finishes. Toolholders include a Weldon shank and coolant bore, and chamfer inserts are available to expand versatility.

• Ground profile for precision and finish: The precision-ground form delivers tight tolerances and a smooth surface finish on grooves, threads, and chamfers, even at higher cutting parameters.
• One insert for right- and left-hand threads: Simplifies stocking and setup, reducing downtime and allowing quick task changes without swapping inserts.
• Secure clamping with Weldon shank and coolant bore: Robust, repeatable holding ensures consistent results across cycles, while coolant-capable toolholders help manage heat and extend insert life.

This combination helps you streamline vertical milling workflows, cut more parts per shift, and achieve reliable, repeatable results across a range of groove, thread, and chamfer operations. The universal RH/LH threading capability reduces inventory complexity, while the coolant-ready, Weldon-shank option supports efficient setups and longer tool life. When paired with chamfer inserts, you gain expanded capability without sacrificing precision or repeatability, making it a dependable choice for precision machining environments.
