Abstract: In friction drilling technique, friction is developed in between work material and rotating tool. In this method, friction heat is generated. Also, material heat is generated and due to this, tool was penetrated without formation of chip and hence this method is classified as a chip less hole making method. One of the issues faced in friction drilling process is excessive wear of tool. To address this issue in the context of copper plate, two different materials of H13 steel tool and HSS tool with two combinations (straight and conical profile) were investigated and compared. For this process, CNC 3 axis machine was used for drilling hole on a 3mm thick copper plate. This study validated that HSS straight profile tool displayed lesser wear of 0.093μm at 50mm/rev feed rate and 3000rpm spindle speed.
