Zusammenfassung:	A tool and a method are for at least one of gripping, expanding, and penetrating a wall of a bore. The tool has a first tool part and a second tool part arranged axially movable relative to each other. The first tool part has a solid wedge, whereas the second tool part has at least one wedge arm. The first tool part further has at least one influencing portion configured to be radially movable upon contact with the at least one wedge arm of the second tool part. The at least one wedge arm is configured to be moved axially along the solid wedge so as to be forced radially outwards and thus push the at least one influencing portion radially outwards.
