Turning grades KC5010 and KC 5025 are primarily applied in finish machining and general-purpose machining of high-temperature alloys, stainless and alloy steels. They also can be used in cast iron and nonferrous applications requiring keen cutting edges.
The company is optimizing the aluminum content in the advanced PVD TiAIN coating, which increases resistance to wear at the cutting edge. Both lab and field testing confirm that this coating enables a 50 to 100 percent increase in surface speed. At the same time, there is no loss of tool performance at conventional speeds.
KC5010 uses a 6 percent cobalt binder in the substrate, which is especially for general-purpose and finish-turning applications without heavy interrupted cuts. For more severe operations, KC5025, with 10 percent cobalt in the base material, offers added toughness to the cutting edge to cope with extreme variations in cutting loads.
