  • Drilling head for an anchor
    Patent number: 7575074
    Abstract: A separate drilling head has a distal end which contacts the material to be drilled, and a proximal end which is attached to a drive mechanism. The drive mechanism drives the separate drilling head into the material. The separate drilling head is forcelockingly secured in a thin-walled hollow anchor tube, and the separate drilling head includes a hard metal cutter element, and a substantially axially-oriented, axial stop shoulder at the proximal end that passes into a circumferentially closed, outer cone.
