Carmex Vertical Milling CMT Three Flute Insert - Groove Milling - C18W12

The Carmex Vertical Milling CMT Three Flute Insert – Groove Milling – C18W12 is a precision indexable insert designed for vertical milling applications, including groove milling, threading, and chamfering. It’s built for engineers, machinists, and shops that need reliable, repeatable performance across a range of groove and thread milling tasks.

Ground-profile inserts deliver high-precision results and outstanding performance at demanding milling parameters, with a robust clamping system that ensures full repeatability. Compatible with right- or left-hand threading, it pairs with weldon shank toolholders and coolant bore options, and chamfer inserts are available to complete the setup.

• Ground-profile inserts for high precision: These inserts are manufactured with a ground profile to achieve tight tolerances and clean cutting edges, delivering consistent groove milling and threading results with less rework.
• High-parameter machining with superior surface finish: Designed to perform reliably at higher cutting speeds and feeds, maintaining a smooth surface finish and reducing cycle times for faster production.
• Universal, repeatable clamping and flexible tooling: Solid, accurate clamping ensures repeatability across multiple parts; the same insert handles both right- and left-hand threads, and compatible toolholders with Weldon shanks and coolant bores are available—the system can also accommodate chamfer inserts for complete operations.

This combination of precision, versatility, and reliable clamping helps you shorten setup times, reduce scrap, and achieve consistent groove profiles across batches—empowering you to hit tight tolerances with confidence and finish on target.
