The Carmex Vertical Milling CMT Three Flute Insert - Corner Rounding (C18CR13MT7) is a precision indexable insert designed for vertical milling tasks. It’s ideal for engineers, machinists, hobbyists, and buyers who need reliable corner radii, chamfers, grooves, and threading work in a single, replaceable module.

Built for demanding environments, this insert uses a ground profile for high precision and excellent surface quality, even at higher machining parameters. Its solid, accurate clamping delivers full repeatability from part to part, and the same insert can be used for right- or left-hand threads. Toolholders include a Weldon shank and coolant bore for quick setup and efficient cooling, with chamfer inserts also available to expand capability.

• Ground profile for precision and surface quality: Delivers consistent geometry and smooth finishes, enabling precise radii and high-quality surfaces at demanding machining parameters.
• Solid, repeatable clamping: Provides reliable tool seating and repeatable results across multiple parts and tool changes with minimal runout.
• One insert for both right- and left-hand threads: Simplifies tooling, reduces inventory, and speeds setup by supporting threading in both directions.

This combination of accuracy, reliability, and versatility helps you streamline your vertical milling workflows, achieve repeatable corner rounding and chamfering results, and maintain consistent part quality across batches with fewer tool changes and less downtime.
