Description

The Carmex Vertical Milling CMT Three Flute Insert – Groove Milling – C25W35 is a precision ground indexable insert designed for vertical milling tasks that include grooves, threads, and chamfers. It’s a versatile solution for engineers, machinists, buyers, and hobbyists who need reliable performance from prototype through production.

Designed to thrive at high machining parameters while delivering a high-quality surface finish, this insert pairs with robust, accurate clamping to ensure full repeatability. The same insert works for both right-hand and left-hand threads, simplifying tooling choices. Toolholders include a Weldon shank and a coolant bore for straightforward integration and effective coolant delivery. Chamfer inserts are also available if you need to clean up edges in a single pass.

  • Precision-ground profile for repeatable accuracy: Ground profiles deliver tight tolerances and dependable performance across cycles, helping minimize rework and ensure consistent parts.
  • High-parameter milling with excellent surface finish: Ready for elevated cutting speeds and feeds, it maintains surface quality and reduces finishing work in grooving and threading operations.
  • Universal threading and reliable clamping with coolant-ready tooling: One insert handles both RH and LH threads, while its solid clamping supports repeatable results; weldon-shank toolholders with coolant bore streamline setup and coolant delivery.

This insert enables a streamlined workflow for groove milling, threading, and chamfering, delivering consistent results with fewer setup changes and less downtime. By combining precise geometry, sturdy clamping, and versatile threading capability, it helps you achieve reliable performance and higher-quality parts in both quick-turn and production environments.
