Nodular cast iron (FCD) has high tensile strength and high hardness. However, in turning of FCD with a cemented carbide tool, the tool wear in turning of FCD becomes larger than that in turning of gray cast iron (FC). Furthermore, in high speed cutting of FCD, the progress of the tool wear increases rapidly with the increase of the cutting speed. In this study, in order to find out the effective tool materials for the high speed turning of the nodular cast iron, a ductile cast iron JIS FCD700 was turned with the various commercial tool materials at the cutting speed from 1.67m/s to 20m/s under the depth of cut 0.3 or 1.0mm and the feed rate 0.2 or 0.4mm/rev. The main results obtained are as follows: (1) In turning of FCD700, the TiN-TiCN-Al<SUB>2</SUB>O<SUB>3</SUB> TiN coated cemented carbide tool is the effective tool materials for wide range of cutting speed, and it can be adapted for the high feed rate. (2) In turning of FCD700 with the TiC added Al<SUB>2</SUB>O<SUB>3</SUB> ceramics tools, the progress of the tool wear becomes slow with the increase of TiC under the cutting speed from 1.67m/s to 5.0m/s. However, in higher speed cutting than 10m/s, the progress of the tool wear becomes fast with the increase of TiC.
