Abstract
A method for integrally forming a drilling tip on a wire nail, in particular in order to produce a screw with the aid of a pair of pinching jaws, provides for the bulge formed by the displaced material during the integral forming of the drilling tip to be sheared off the drilling tip along the entire length of the cutting edges of the drilling tip produced and to be left connected to the drilling tip only along the longitudinal side edges of the latter by a predetermined breaking point.
