The Carmex Vertical Milling CMT Three Flute Insert with Corner Rounding (C18CR20MT7) is a high-precision, indexable insert designed for vertical milling tasks. Built for engineers, machinists, and production teams, it excels at corners, chamfers, grooves, and threading with consistent accuracy and surface quality.

• Three-flute geometry for stable corner rounding: Delivers smooth cutting action and efficient chip evacuation, producing clean corner radii even at higher feed rates and machining parameters.
• Ground profile for precision under high speeds: Tight tolerances and superior surface finish help reduce secondary finishing and maintain accuracy across demanding milling operations.
• RH/LH threading support with coolant-ready toolholders: The same insert handles both right- and left-hand threads, while toolholders include a Weldon shank and coolant bore for secure clamping and direct coolant delivery, enabling quicker setups and consistent results.

This insert is designed to simplify production workflows by combining versatile threading, grooving, and chamfering capabilities into a single, reliable solution. Its robust clamping and precise geometry help minimize setup time and rework, delivering repeatable performance and dependable results across a range of materials and applications.
