The Carmex Vertical Milling CMT Three Flute Insert for Groove Milling is a purpose-built, indexable insert designed for vertical milling operations. It enables grooves, threads, chamfers, and other profiles with a single, versatile solution when used with compatible toolholders. Ideal for engineers, shop technicians, and hobbyists, it delivers dependable performance across a wide range of materials and production needs.

Engineered for precision and consistency, the ground-profile insert maintains tight tolerances and a high-quality finish while you push cutting parameters. Its robust, repeatable clamping ensures consistent results across setups, helping you reduce downtime and rework.

• Ground profile for precision and surface quality: The precision-ground geometry delivers consistent accuracy and smooth finishes, enabling reliable groove milling and threading even at higher speeds and feeds.
• Robust, repeatable clamping: A solid, accurate clamping method minimizes setup variation, delivering repeatable results and faster changeovers.
• Universal threading and toolholder compatibility: One insert handles both right-hand and left-hand threads, and works with toolholders that include Weldon shanks and coolant bores; chamfer inserts are available to extend capability.

This combination helps you streamline production: fewer tool changes, simpler inventory, and reliable performance from setup to finish. The consistent geometry, secure clamping, and flexible threading options enable you to achieve precise grooves, accurate threads, and clean chamfers with less guesswork—improving throughput and part quality in everyday machining.
