Cutting edges featuring the coating offer the potential for a significant increase in cutting speed during boring, even when dry machining, says Mapal. For instance, machining is possible at 300 m/min, thus offering a considerable boost in productivity. At the same time, the cutting edges achieve longer tool life, as recent trials showed: when machining GJL25, tool life was tripled in comparison with the existing PVD cutting material HP455.
The entire standard Mapal product range of indexable blades for ISO boring tools is available with the latest HC7 cutting material series.
