The tool life in turning of the sintered steels becomes shorter than that in turning of the melted steels such as carbon steels. In order to clarify an effective tool material for the high speed turning of the forged sintered material, the tool wear was experimentally investigated. The forged sintered material was turned with various tool materials at the cutting speed 5 m/s, the feed rate 0.2 mm/rev and the depth of cut 0.1mm. The main results obtained are as follows: (1) The abrasive wear was remarkably found on the worn surface of the coating layer in all PVD coated cemented carbide tools. (2) The wear progress of Ti75V25N PVD coated tool was slowest, because the Ti75V25N coating layer had high micro Vickers hardness and high critical load measured by the scratch test. (3) In the Al<SUB>2</SUB>O<SUB>2</SUB>-TiC ceramics tool, the tool wear decreased with the increase of the TiC contents. The wear progress of the 30%Al<SUB>2</SUB>O<SUB>3</SUB>-70%TiC ceramics tool was slowest among four ceramics tools. However, the wear progress of the 30%Al<SUB>2</SUB>O<SUB>3</SUB>-70%TiC ceramics tool was faster than that of the Ti75V25N PVD coated tool. The wear progress of both Al<SUB>2</SUB>O<SUB>3</SUB> ceramics tool and Si<SUB>3</SUB>N<SUB>4</SUB> ceramics tool was rapid.
