Carmex Vertical Milling CMT Multi Flute Insert - Threading - S163H1.0ISOMT8 is a vertical milling indexable insert system designed to handle threading, grooves, chamfers, and more. Built for precision and efficiency, it uses ground-profile inserts to deliver accurate, repeatable results at demanding cutting parameters and with a high-quality surface finish.

Whether you’re a design engineer, machinist, toolroom technician, or hobbyist, this system helps you achieve precise threads quickly and reliably. The same insert works for right-hand or left-hand threads, and the toolholders include a weldon shank and coolant bore for versatile, dependable operation. Chamfer inserts are also available to expand your capabilities in a single, coherent system.

• Ground-profile inserts for high precision: Delivers consistent, accurate threading and grooves with excellent performance across challenging materials.
• Solid, repeatable clamping: Ensures stable cutting and repeatable results even under high machining parameters and demanding cycle times.
• Bidirectional threading with versatile holders: Use one insert for both right- and left-hand threads; toolholders include weldon shank and coolant bore, with chamfer inserts available for expanded versatility.

This setup helps streamline your workflow by reducing tool-change frequency and inventory while delivering cleaner threads, smoother finishes, and reliable performance across a range of milling operations.
