Abstract

The drill tool for rotary or percussive drills, has a drill head (10) with a pilot (11) and reamer (12). A guide (16), guides the drill tool relative to the casing tube (15) which surrounds the guide (16). Downward axial movement of the casing (15) and guide (16) is achieved by a cooperating drive (18, 19). The cooperating drive is achieved by a tongue and groove arrangement in the casing tube and the guide. The rotation of the guide is thus transferred to the casing tube.
