The main object of the present paper is to discuss cutting temperature of the drill point in low frequency vibratory drilling of SUS304. Although many studies dealt with the drill wear in conventional drilling have been presented, there has been hitherto no study dealing with cutting temperature of the drill point in low frequency vibratory drilling of SUS304. For this reason, cutting temperature of drill point in low frequency drilling of SUS304 was chosen as a subject of our studies, that is, cutting temperature at the drill face was measured by using of some cobalt high speed steel drills which brazed a sheathed thermocouple, and the experimental results were compared with those in conventional drilling. On the other hand, cutting temperature of drill point was computed by finite element method. From this study, distribution of cutting temperature of drill point was clarified.
