A hole forming tool comprises a cylindrically shaped body (2) having a longitudinal axis and at least one aperture at the base thereof, and at least one blade (3) extending from the base of said cylindrically shaped body, this blade or blades being arranged such that, in use, it facilitates the displacement of soil in a substantially lateral direction with respect to the longitudinal axis of the body. The blade or blades extend in a direction substantially parallel to the longitudinal axis of said cylindrical body. The blade or blades may be arranged so as to extend across the diameter of said cylindrically shaped body.
