The Carmex Vertical Milling CMT Three Flute Insert - Groove Milling - C10W087 is a precision indexable insert designed for vertical milling tasks such as grooves, threads, and chamfers. It’s built for engineers, machinists, and fabricators who need reliable, repeatable results across a variety of materials and applications.

Ground-profile inserts deliver exceptional precision and consistent performance, even at higher machining parameters, helping you achieve superior surface quality with fewer finishing passes. The solid, accurate clamping method ensures full repeatability from part to part, and this single insert design accommodates both right-hand and left-hand threads. The accompanying toolholders feature a Weldon shank and a coolant bore for straightforward setup and dependable coolant delivery. Chamfer inserts are also available for dedicated finishing operations.

• Precision-ground profile: Delivers tight tolerances for grooves and threads with consistent geometry and reliable repeatability across batches.
• High-parameter performance and surface quality: Optimized geometry supports higher speeds/feeds while delivering excellent surface finishes, reducing secondary operations.
• Universal threading with robust clamping: One insert handles both right- and left-hand threads, paired with solid clamping and options for Weldon shank and coolant bore; chamfer inserts are available for dedicated finishing.

Designed to streamline production, this insert helps you reduce tool changes, minimize downtime, and achieve dependable results on demanding groove and thread work. Its durable construction and precise engineering translate to consistent performance, smoother setups, and faster cycle times—so you can complete tighter tolerances with confidence on every job.
