Carmex Vertical Milling CMT Three Flute Insert - Threading - C12I1.5ISOMT7 is a precision vertical milling insert designed for threading, grooving, chamfers and related finishing tasks. When paired with compatible CMT vertical mill-thread toolholders, it delivers repeatable performance in demanding metalworking environments. This system is ideal for engineers, machinists, and hobbyists who need reliable, versatile threading capability in a compact, easy-to-use package.

Built around ground-profile inserts for high precision and excellent surface quality, the CMT Vertical Mill-Thread solution keeps you cutting at higher parameters without sacrificing finish. A solid, accurate clamping method ensures full repeatability, while a single insert works for both right-hand and left-hand threads. The set includes toolholders with weldon shank and a coolant bore, and chamfer inserts are available to broaden your threading and finishing options.

• Three-flute geometry for efficient threading: Optimizes chip evacuation and stability, delivering clean, consistent threads even at higher cutting speeds.
• Ground-profile inserts for precision and finish: Delivers tight tolerances and superior surface quality, enabling repeatable results across jobs and materials.
• Universal threading with secure clamping and coolant options: One insert handles both RH and LH threads, with a robust clamp and a coolant bore for quick setup and effective cooling.

This combination helps you streamline setups, reduce downtime, and achieve reliable threading results across a variety of applications—from threads to grooves and chamfers—while maintaining high surface quality and long tool life.
