Carmex Vertical Milling CMT Three Flute Insert - Groove Milling - C18W20

The Carmex Vertical Milling CMT Three Flute Insert – Groove Milling is a precision, indexable insert designed for vertical milling tasks such as grooves, threads, and chamfers. It’s built to serve a wide range of metalworking needs, making it suitable for engineers, buyers, tradespeople, hobbyists, and non-technical customers who require reliable, repeatable results.

Featuring a ground-profile insert and a three-flute geometry, this solution delivers high precision and excellent performance across demanding cutting conditions. When used with compatible toolholders, it supports high machining parameters while maintaining a high-quality surface finish. The system relies on a solid, accurate clamping method to ensure full repeatability, and the same insert can handle both right-hand and left-hand threads. Chamfer inserts are also available to expand capability.

• Ground-profile precision for consistent groove and thread results: Ground profiles provide tight tolerances and stable engagement, improving accuracy on grooves and threaded features and reducing chatter.
• High-parameter performance with a superior surface finish: Designed for aggressive milling conditions, it maintains excellent surface quality even at higher speeds and feeds in groove milling and threading tasks.
• Universal RH/LH compatibility and coolant-ready tooling: The insert works for both right- and left-hand threads and pairs with toolholders that include a weldon shank and a coolant bore for fast setup and reliable coolant delivery.

This vertical milling solution simplifies setup, supports efficient production workflows, and delivers repeatable, high-quality results across grooves, threads, and chamfers. It’s a versatile choice for shops aiming to reduce downtime and keep precision consistently at the forefront of their milling operations.
