The tool life in turning of the sintered materials such as sintered steel becomes shorter than that in turning of the melted steels such as carbon steel. In order to clarify the effective tool materials for the turning, the tool wear etc. in the turning of the sintered iron material was experimentally investigated. The sintered iron material was turned with the various tool materials at the cutting speed 5.0m/s. The main results obtained are as follows: (1) In the PVD/CVD coated cemented

And, the wear progress of the Si3N4 ceramics tool became slower than that of the TiVN PVD coated cemented carbide tool. (3) The main wear mechanisms of the ceramics tools were the abrasive wear.
