Abstract: Drill for making a pole in the ground, whereby this drill (9) is provided with a passage (15) and whereby this drill has at the bottom a screw-shaped displacement part (11) of which the outside increases in radius upwardly, up to a diameter larger than that of the drill tube (8), characterized in that the displacement part (11) passes with its upper extremity into a cylindrical part (12) which is provided on its mantle with at least a screw blade (13) which runs in the shape of a screw in the same direction as the displacement part (11), but of which the pitch (S2) is larger than the pitch (S1) of the displacement part (11).
