ABSTRACT:
A connection point (1) between two tool parts is proposed which are joined by means of a threaded spindle (7) oriented in longitudinal direction of the tool parts. The threaded spindle has two oppositely threaded sections (13, 15) which interact with two threaded areas (17, 19) in the tool parts. The connection point (1) is distinguished in that at least one end area of the threaded spindle (7) has a shoulder (63), the outside diameter of which is smaller that the interior diameter of the associated threaded area (17).
