Added with nano composite powder material, controlled ring structure and strengthened binder phase give the material outstanding wear resistance and toughness, with longer service life and stability.
Extra fine rich W phase even dispersion improves thermal conductivity, hot-cracking resistance and plastic deformation resistance.
Perfect Ta/Nb proportion combined with high N content gives excellent red-hardness.
Covering wide range of applications from finishing to semi-finishing, with good surface quality.
New surface treatment techniques make more stable cutting!
