Drill bit with an exchangeable cutting portion

A drill bit which is rotatable about a drilling axis, comprising:

• a cutting section having one or more cutting segments and a first plug-connecting element;
• and
• a drill shaft section having a second plug-connecting element,
• wherein the first plug-connecting element and the second plug-connecting element form a plug connection with an outer plug-connecting element and an inner plug-connecting element, wherein the inner plug-connecting element is closer to the drilling axis than the outer plug-connecting element and the outer plug-connecting element is farther away from the drilling axis than the inner plug-connecting element in a plane perpendicular to the drilling axis,
• wherein the first plug-connecting element and the second plug-connecting element are connectable by a pin connection, wherein the pin connection has at least one receiving borehole and at least one pin element which is insertable into the at least one receiving borehole,
• wherein the at least one pin element is a loose pin element and the at least one receiving borehole passes completely through one of the first and second plug-connecting elements and passes at least partially through another of the first and second plug-connecting elements, and
• wherein the at least one receiving borehole is at least as deep as the pin element.
