A tool magazine includes at least one tool carriage movable along a circulation path. The tool holders each have tool pot sockets to which the tool pots are mountable. The tool holders are disposed pivotably about a pivot axis with respect to the at least one tool carriage. The tool pot sockets include a first and second tool pot sockets. An angle is created in a pivoting direction about the pivot axis between a first tool pot mounted to the first tool pot socket and a second tool pot mounted to the second tool pot socket. The turning device turns each of the tool holders about the pivot axis at a position on the circulation path. The tool pot stopper positions each of the tool pots and stops one of the first tool pot and the second tool pot at a pivotable location in the pivoting direction.
