'General purpose roughing and finishing - SV325 delivers outstanding performance in moderate roughing to semi-finishing operations, especially in interrupted cuts. An advanced multi-layer caoting (TiCN/Al2O3/TiN), applied over a cobalt enriched substrate, gives SV325 a near optimum balance of toughness, surface lubricity, and resistance to metal build-up to yield excellent wear resistance thoughout its application range.'
