Abstract

The present invention provides a fabrication method of screwdriver bit, and particularly a fabrication method of screwdriver bit for saving material and enhancing strength. The method at least includes a step of material preparation and a step of forge forming. During the forge forming step, one end of the screwdriver bit is recessed to form a recessed hole, and the other end is formed with a necked section at the site of a toothed positioning slot. The free end of the necked section may have a head portion having the corresponding specification and form. Thus, the present invention employs direct forging on a piece of raw material for greatly saving a required amount of material, which cannot only reduce the weight, but also reduce the manufacturing cost. Moreover, the design for forming rib slots on an outer periphery of the necked section during forge forming can increase the distortion level for extending the product lifespan.
