Product Description:

The TCMT11T308-PM 4325 is a high-efficiency triangular turning insert from Coromant, optimized for medium to continuous cutting of steel (ISO P). Built with the premium 4325 universal wear-resistant carbide grade and equipped with the reliable PM chip-breaker, this insert delivers exceptional edge strength, long tool life, and stable performance under demanding cutting conditions.

The PM chip-breaker ensures smooth cutting action, excellent chip control, and reliable operation from roughing to semi-finishing. Its advanced coating enhances resistance to plastic deformation, oxidation wear, and edge chipping, making it ideal for mass-production environments and long-duration machining.
