The Carmex Vertical Milling CMT Three Flute Insert for Groove Milling is a precision indexable insert designed for vertical milling applications that create grooves, threads and chamfers. It’s ideal for shops and jobs that demand repeatable accuracy, high productivity, and clean, consistent finishes across a range of materials.

Ground profile inserts deliver high precision and excellent performance, even when cutting at higher parameters. This enables strong surface quality and reliable results in groove and thread milling, helping you maintain tight tolerances over long production runs. The solid, accurate clamping method ensures full repeatability between tools and setups, so you can trust consistent outcomes every cycle. The design is versatile enough to handle both right-hand and left-hand threads with the same insert, simplifying tooling and inventory. Toolholders include a Weldon shank and coolant bore, and chamfer inserts are available to expand your groove-milling capabilities.

• Precision-ground profile for consistent accuracy: Delivers exact geometry for grooves and threads, ensuring tight tolerances and smooth tool paths across multiple parts.
• High-parameter performance with repeatable clamping: Supports aggressive cutting with excellent surface finish while maintaining alignment and repeatability through multiple tool changes.
• RH/LH threading compatibility with coolant-ready holders: The same insert works for both thread directions, reducing tooling investments; Weldon-shank holders with coolant bore enable efficient cooling and chip evacuation, with chamfer inserts available for a complete groove-milling workflow.

Using this integrated groove-milling solution helps you streamline workflows, reduce setup and changeover times, and achieve repeatable, high-quality results. The combination of a precise ground profile, robust clamping, and versatile threading support translates to fewer interruptions, longer tool life, and more predictable production performance in demanding milling tasks.
