- connection interface 18c has four securing elements 26c, 30c, 42c, 44c for axial securing on the quick-action clamping device and for transmitting a torque when the connection interface 18c is arranged on the quick-action clamping device.
- the securing elements 26c, 30c, 42c, 44c at least partially form the boundary edge 24c.
- the connection interface 18c has four tool assembly coding elements 28c, 46c, 48c, 50c arranged at a distance from the securing elements 26c, 30c, 42c, 44c.
- the tool assembly coding elements 28c, 46c, 48c, 50c at least partially form the boundary edge 24c.
- the tool assembly coding elements 28c, 46c, 48c, 50c are intended to interact with at least one assembly coding element of the tool holder when the connection interface 18c is arranged on the tool holder.
- the tool assembly coding elements 28c, 46c, 48c, 50c each have a projection 34c on the boundary edge 24c with an axially projecting component.
- the tool assembly coding elements 28c, 46c, 48c, 50c are each formed as a projection 34c with an axially projecting component.
- the securing elements 26c, 30c, 42c, 44c each have contact surfaces 98c running at least substantially parallel to a tool axis of rotation (not shown here). The contact surfaces 98c are intended to cooperate with the tool holder 14c, in particular the quick-action clamping device 20c, to axially secure the connection interface 18c on the tool holder 14c, in particular the quick-action clamping device 20c.
- the projections 34c each protrude from a plane defined by the contact surfaces 98c.
- the tool interface device 10c has a surface 36c surrounding the connection interface 18c.
- a main extension plane of the surface 36c is spaced apart from a main extension plane of the four securing elements 26c, 30c, 42c, 44c, the projections 34c with an axially protruding component being at least essentially completely between the main extension plane of the surface 36c surrounding the connection interface 18c and the main extension planes of the securing elements 26c, 30c, 42c, 44c.
- the main extension planes of the securing elements 26c, 30c, 42c, 44c run at least essentially parallel to their contact surfaces 98c.
