NTK PVD Carbide TBP/TBPA-BM - Poppet valve - DM4
With conventional products, surface roughness caused by progressive wear was a major issue.
In contrast, DM4 suppresses heat-induced tool damage even under high-temperature cutting conditions, improving surface finish quality.
As a result, tool life was extended by 1.75 times.
