Abstract

Method for making a form-fitting connection between a tool insert and a tool holder of a rotatingly driven tool, wherein the tool holder has bearing surfaces by which forces or torques are transmitted to the tool insert, wherein the tool insert is made from a material harder than that of the tool holder and by sintering a green compact of powder. A sintered green compact for the tool insert is used as a hob, by which the bearing surfaces in tool holders are manufactured by punching or press-forming.
