This paper describes a basic machinability of hardened steel in precision cutting. High accuracy and high efficiency machining of micro parts such as a contact probe for a current inspection of semiconductor has been demanded. For its realization, it is essential to understand the micro cutting phenomenon such as the surface texture, the tool wear with small depth of cut and low cutting speed. In this study, the precision cutting experiments of a carbon tool steel (SK105) by cermet and ultra-fine grained carbide tools were carried out with an ultra-precision cutting machine. It was found that the feed rate, the cutting speed and the edge sharpness of tool significantly influence the surface finish.
