Featuring a Super ZX multi-layered coating, Sumitomo Electric Carbide's AC510U and AC520U grades are suited for roughing, finishing and medium-cut machining of super alloy materials. The coating consists of thin layers of TiAlN and AlCrN alternately stacked to 1,000 layers, resulting in high speed capabilities and great wear resistance.
