Abstract

The invention relates to a self-drilling injection anchor (1), in particular an integral injection anchor, with a continuous flight on the circumferential-wall side and a drill bit arranged at one end and having allocated cutting edges (7, 8), and a centre passage (3), running in the axial direction and ending in the area of the drill bit, for supplying a flushing medium or the like; in order to obtain as simple a design as possible, it proposes that the cutting edges (7, 8) be formed as welding beads on the annular surface (6) surrounding the passage orifice (5). <IMAGE>
