Abstract

In a process for driving in a self-boring, self-piercing, thread-shaping or thread-cutting screw (1), an axial percussion effect (6) is added to the rotary drive (7) during the hole boring step. During the thread-shaping step, the axial percussion effect is stopped and only the rotary drive remains.
