Abstract
A tool structure contains a first part having an oval end section with regard to an axis of symmetry in a direction of a maximum height and an axis of symmetry in the direction of a maximum width, and a second part having a recess accommodating the end section via mutual contact surfaces. The tool structure has a clamping element for the mutual clamping of the parts and mutual contact surfaces that are restricted to in each case four spaced-apart surface sections. These surface sections are disposed symmetrically with respect to a circumference of the end section such that a center point of a straight connecting line of the starting and end points of the respective surface section is at a normal distance bfrom the axis of symmetry and at a normal distance hfrom the axis of symmetry, hbeing greater than b.
