Grooving wear on bounday portion of tools in machining SUS 304 is mainly caused by adhesive action between tool and work materials from 1st and 2nd reports. It may be considered that the above adhesive action is influenced by adhesion of Co in tool material and Ni in work marterial. Accordingly, in order to investigate influences of tool material on grooving wear, turning tests are performed with various carbide tools including different amount of Co, which are specially made for this study. From this study, following resuts are mainly obtained. (1) Grooving wears in case of WC-Co type carbide tools are mainly caused by high temperature after adhesive action of tool material and work material because their tool materials have not enough heat resistance. In case of WC-Co-TiC-TaC type carbide tools, grooving wears are caused by chipping after adhesion because their tool materials have not enough toughness. (2) In case of machining SUS 304 using WC-Co type carbide tools, the criterion of tool life must not be taken by flank wear but grooving wear.
