Abstract: A removal tool includes an elongate rod. A first end of the elongate rod is to be connected to and driven by a drive device, and a second end of the elongate rod is connected integrally to the first end. A direction from the first end toward the second end, which is substantially parallel to a longitudinal center axis of the elongate rod, is defined as a first direction. Along the first direction the second end is conically tapered and formed with plural splines which obliquely extend relative to the longitudinal center axis according a twist direction, wherein the twist direction generally conforms to a direction in which the removal tool is used to unfasten a fastener. Each spline has a circumferential surface having plural first teeth which obliquely extend relative to the longitudinal center axis according to the twist direction along the first direction.
