Employs our super multi-layered New Super ZX Coat, which utilizes our proprietary thin-layer coating technology and advanced nanotechnology. The coating consists of thousands of alternating, nanometer-thin (1 nanometer=1 billionth of a meter) layers. Compared to conventional tools, the coating hardness has been increased by 40% and the oxidization starting temperature has been increased by 200°C. Enables more than 1.5 times the machining speed and efficiency of conventional tools. Achieves more than double the tool life of conventional tools under the same cutting conditions.
