The invention relates to a machine tool for introducing bores into a workpiece, said machine tool comprising a machine frame, a drilling tool holder which is arranged on the machine frame and has at least one tool spindle, and a workpiece carrier which is arranged on the machine frame, the boring tool holder and the workpiece carrier being displaceable in relation to each other in a direction of displacement. A longitudinal direction of the at least one tool spindle is oriented transversally in relation to a horizontal plane, and the drilling tool holder is arranged on the machine frame in such a way that it can be pivoted in relation to the workpiece carrier, so that inclined bores can be introduced into the workpiece.
