Abstract
The self-undercut anchor with carbide tip is designed to create a drill hole and enlarging the lowermost end of said drill hole by means of a carbide tip or cutting portion. The carbide tip or cutting portion is positioned in such a way so as to not obstruct the setting of the anchor by means of the spreading lamellae. Once said lamellae have been positioned properly and forced downward, the self-undercut anchor is set in place.
