A milling tool for cyclo-palloid toothing has a holder and multiple first cutting plates. and includes a clamping portion for clamping the holder and a holder head, which projects radially compared to the clamping portion in the front end and on which there are multiple first cutting plate receptacles. The first cutting plates are fastened in the first cutting plate receptacles, and project radially outward, wherein the radially outermost points of the first cutting plates lie in each case on a common circle, the center point of which lies on the center axis of the holder. The first cutting plates are arranged at an angle to an orthogonal plane which is orthogonal to the holder center axis. Multiple first partly conical surfaces are provided on a top side of the holder head. Multiple second partly conical surfaces are provided on an end side of the holder head.
