While wear- and deformation-resistant NL200 is intended for machining cast iron, wear-resistant NL250 is suited for semi-finishing and finishing applications. Medium and rough machining of steels and cast iron materials with light scale but no interruption can be accomplished with NL300, and NL400 handles medium and rough machining on stainless steel and exotic alloys. Fine grain NL920, with edge security on steels and stainless steels, serves rough and heavy machining applications.<br />
