Abstract

The drill has an energy transfer piece, a drill hammer which is shaped and forms a drilling shaft (9). There is a guide (10) adjacent to the shaft with an eccentric auger (11) mounted at the end of it. When drilling, the auger is outside the hole lining tube (8), but it can be turned to fit inside and be retracted through the tube. The guide is non-rotatably connected to the shaft, while the auger is mounted at the end of the shaft, with limited rotation. The rotation angle is at least 90 deg. and pref. 180 deg.
