Use as a general-purpose grade for non-ferrous materials.

                                                                                  N Non-Ferrous

                                                                                  Application: The KC5010 grade is ideal for finishing to general machining of most workpiece materials at higher speeds. Excellent for machining most steels, stainless steels, cast irons, non-ferrous materials, and super alloys under stable conditions. It also performs well machining hardened and short chipping materials.
