The invention relates to a tool turret, comprising a tool disk (1), which has at least one tool receptacle (7) for a machining tool and which is fastened to an accommodating disk (51), which can be swiveled about a support column that defines a swivel axis into positions in which the particular machining tool is in a working position, a contact surface (55) being provided on the tool disk (1), wherein said contact surface can be clamped to an accommodating surface (53) on the accommodating disk (51) by means of a clamping device. The tool turret is characterized in that the clamping device has an annular groove on one (51) of the two components (1, 51) to be clamped, said annular groove being concentric to the swivel axis and being open radially outside and having at least one inner slanted surface (81), and the clamping device has at least one compression piece (57) on the other (1) component, said compression piece penetrating the annular groove (61) under compressive force and having a wedge surface (79), which in interaction with the slanted surface (81) of the annular groove (61) produces a force component as a clamping force from the compressive force, which presses the contact surface (55) and the accommodating surface (53) against each other.
