The tip of a self-drilling screw is shaped with a point and flute that resembles a drill bit. A notched area in the tip behaves as a reservoir to receive chips or filings as the material is carved away by the screw (when drilled). Thanks to this specialized tip, the self-drilling screw allows assemblers to skip the initial step of drilling a pilot hole.
