Abstract: An earth displacement drill is provided including a drill tube which can be driven for rotary movement and a boring tip connected thereto, wherein the boring tip has a cylindrical part which adjoins the drill tube and has at least two helical strips uniformly distributed around the circumference, which climb upwardly at a shallow angle, with the flat side of the strips preferably extending substantially parallel to the radius at the relevant position and in particular only over a fraction of the circumference of the cylindrical part. The boring tip also has a tapering part located beneath the cylindrical part and having at least two arched surfaces which are uniformly distributed around the tapering part. These arched surfaces expediently extend approximately parallel to the vertical and preferably more steeply than the helical strips.
