NTK PVD Carbide – Precision Machine Parts – ST4
NTK PVD Carbide - Precision Machine Parts - ST4
Conventional tools suffered from unstable dimensional accuracy and surface finish, resulting in unstable machining.
ST4, featuring superior coating adhesion and enhanced surface smoothness, suppresses built-up edge (BUE), a common issue in stainless steel machining. As a result, it delivers stable dimensional accuracy and improved surface quality.
This performance leads to a 1.3 times longer tool life.
