The Carmex Vertical Milling CMT Three Flute Insert is a precision indexable insert designed for groove milling and vertical mill-thread applications. It’s ideal for engineers, machinists, and shops that demand accurate groove cuts, clean threads, and dependable, repeatable results.

Ground-profile inserts deliver high precision and excellent performance, even at higher cutting parameters, with a smooth surface finish. The solid, accurate clamping method ensures full repeatability across jobs, while the same insert accommodates both right- and left-hand threads. Toolholders include a Weldon shank and a coolant bore, and chamfer inserts are available for finishing touches.

• Ground-profile inserts for precision: Tight tolerances and excellent surface finish enable reliable groove and thread milling, even at higher machining parameters.
• Solid, repeatable clamping: Secure seating reduces runout and delivers consistent results across parts and operators.
• Three-flute design for versatile cutting: Efficient material removal for grooves and threads, with one insert usable for right- or left-hand threads and compatible with Weldon shank toolholders and coolant bore for improved chip control.

This combination helps you speed up setups, maintain consistent quality across lots, and keep workflow flowing with fewer tool changes—delivering dependable performance for both practical manufacturing tasks and precision finishing.
