The Carmex Vertical Milling CMT Multi Flute Insert - Threading - S178F9UNMT8 is a precision, indexable insert designed for vertical milling tasks that encompass threading, grooves, chamfers and more. When paired with compatible tool holders, it offers a versatile solution for engineers, buyers, tradespeople, hobbyists, and workshop professionals seeking reliable, high-quality performance.

Built for demanding production, the ground profile delivers tight tolerances and a high-quality surface finish at elevated cutting parameters. Its solid, accurate clamping ensures full repeatability, while the same insert can handle both right-hand and left-hand threads, simplifying setup and inventory. Chamfer inserts are also available to extend the system’s versatility.

• Ground profile for high precision: Ground profile inserts deliver tight tolerances and excellent surface quality, enabling stable performance at higher machining parameters.
• One insert, right- or left-hand threads: The same insert handles both right-hand and left-hand threads, reducing stocking needs and speeding up setup with consistent results.
• Integrated toolholding with coolant bore: Toolholders include a Weldon shank and coolant bore for easy mounting, reliable coolant delivery, and extended insert life.

In practice, this system helps you streamline setups, maintain precise threads and chamfers, and sustain productivity across milling tasks. The combination of ground-profile inserts, robust clamping, RH/LH versatility, and coolant-ready toolholders supports repeatable, high-quality results and longer tool life in demanding vertical milling applications.
