Sandvik CoroMill 390 vs ISCAR HELIDO H490
CoroMill 390 and HELIDO H490 both machine 90-degree shoulders, but their strongest use cases differ. CoroMill 390 is a broad light-cutting shoulder platform, while H490 emphasizes double-sided inserts and productive roughing of deeper shoulders and high edges.
