This paper describes the adhesion of cutting tools at high temperatures from the results of empirical cutting data and fundamental test on the adhesion between cutting tool tips and work materials. The adhesive tests were run in vacuum except where noted by means of the Vickers hot hardness testing machine. In consequence, we found that the critical temperature for adhesion was affected by the chemical composition of ceramics and kinds of metals and that the strength of the interface between ceramic tips and metals was weaker than in the case of carbides and this fact was recognized as one of the reasons why the crater wear and built up edge in ceramics were less than in carbides.
