Abstract
A tip is described which extends axially along a central longitudinal axis and is configured to displace the ground when the tip is being rotated about its central longitudinal axis during a ground displacement operation for a foundation pile. The tip comprises a tip body; several spiral-shaped ribs protruding from the tip body; and several protrusions arranged to the ribs. The protrusions comprise a point which is arranged such that, during rotation of the tip about its central longitudinal axis, the point of the protrusion is ahead of the rib to which the protrusion is arranged. The tip body, the ribs and the protrusions are made as a single-piece casting.
