Kennametal KCK20B and KCKP10 grades increase productivity in cast iron, compacted graphite cast iron machining

Kennametal has introduced the KCK20B and KCKP10 indexable milling grades for machining cast iron alloys, including grey cast iron, ductile cast iron, and compacted graphite cast iron. According to the manufacturer, both grades enable higher productivity and consistent, repeatable performance during roughing, semi-finishing, and finishing operations.

Available for many of the company’s indexable milling product lines, the new grades come with a golden top layer for fast, easy wear identification.

The new grades were created using high-power impulse magnetron sputtering (high-PIMS) technology that creates a smooth insert surface and optimal layer adhesion for reducing flank wear. The new coating technology also increases cutting edge strength.

While KCK20B delivers higher productivity in roughing and semi-finishing operations, KCKP10 is applicable for finishing operations, but also works well for profiling and copy milling cast iron and steels up to 45 HRC.

Both grades are suitable for wet or dry cutting.
