In order to prevent depth-of-cut notch wear of a cBN tool in Inconel718 cutting, BUE extrusion behavior was focused. Turning tests were conducted to make a comparison between commercial and well-designed tools. The life time of the well-designed tool for stable BUE extrusion is roughly twice longer than that of the commercial tool. The tool with positive rake angle is effective to be stable BUE extrusion. As the results of the turning test considering rake angle, the notch wear hardly appears on the well-designed tool at 1200 m cutting length while the commercial tool fractures in a macro scale less than 1000 m.
