Carmex Vertical Milling CMT Multi Flute Insert – Grooving – SG170FW25MT8 is a high-precision, indexable tool insert designed for vertical milling tasks that include grooves, threads, and chamfers. It’s built for professionals across engineering, fabrication, and maintenance who need reliable performance in demanding machining environments.
This ground-profile insert pairs with compatible toolholders to deliver accurate cuts at high machining parameters, with a solid clamping method that ensures repeatable results whether you’re producing right-hand or left-hand threads.

• Ground-profile precision for consistent cuts: Ground profile inserts deliver high precision and excellent performance, enabling clean, accurate cuts at high machining parameters and producing high-quality surface finishes in threads, grooves, and chamfers.
• Solid, repeatable clamping for reliability: The tool’s rigid clamping method minimizes runout and tool deflection, delivering full repeatability and reducing setup time between jobs.
• RH/LH threading versatility with ready-to-use toolholders: The same insert handles both right- and left-hand threads, and toolholders include a weldon shank with a coolant bore for flexible, easy setups and fast changes.

This combination of precision geometry, secure clamping, and versatile mounting helps you complete complex milling tasks more efficiently—delivering consistent threadforms, grooves, and chamfers with fewer adjustments. It supports higher productivity by enabling faster setups, reducing rework, and expanding your tooling options on a single, reliable insert system.
