<p>A method and device for drilling, particularly percussion drilling or rotary percussion drilling a hole in soil or rock material and fixing an anchoring in the hole. To this end, a drilled hole is made by a drill bit mounted on a drill rod. The drill rod, on the rear side facing away from the drilling surface of the drill bit, is surrounded at a distance from the drill bit by an anchoring element whose outside dimension exceeds, at least in part, the circumference of the drilled hole made by the drill bit.</p> |
