NTK PVD Carbide – Precision Machine Parts – DM4

NTK PVD Carbide - Precision Machine Parts - DM4

With the conventional product, surface roughness and cutting‑edge damage were issues.
DM4 suppresses wear progression caused by elevated cutting temperatures and reduces built‑up edge, resulting in a more stable surface finish.
As a result, longer tool life was achieved, extending tool life by 1.6 times compared with the conventional product.
