Abstract (en)

[origin: WO2013053811A2] The invention relates to a tool system comprising a tool holder and a shank tool, the tool holder having a tool receiving opening with a first and a second diameter region which lead into one another via a transition section (narrowing) and a tool shank of the shank tool has a first and a second cross-sectional region which lead into one another via a transition section. To achieve a design for a tool system of this type that is optimised in terms of wear, the transition sections of the shank tool and the tool holder are interspaced in the direction of the central longitudinal axis of the shank tool to form a repositioning area.
