  • Patent number: 10882099
    Abstract: A tool manufacturing method includes the steps of preparing a cylindrical blank, dividing the blank into sections, changing an outer diameter of one of the sections, and shaping the sections to complete a tool. During the shaping step, the section whose outer diameter is changed is shaped into a symmetrical polygon for serving as a head portion of the tool and shaping another section to obtain a polygon with alternate concavities and convexities thereon for serving as an engaging portion of the tool. Accordingly, the progressive execution of the method prevents the deterioration of the blank made of a high carbon content metal material, allows the tool to keep good mechanical properties, increases the manufacturing efficiency, and reduces manufacturing costs.
