Abstract
A soil shaft-cutting tool has a shaft (2) with a coaxial central axis (1) with a cutter for the removal of soil in the lower part (12) of the shaft. The upper part of the shaft has a connector (6) to the shaft drive. The lower part of the shaft has cutter blades connected to a helix (21,22). The distance between the cutter and the drill axis decreases with increasing height of the cutting edge along the axis.
