A rotatingly drivable cutting head with at least one cutting insert, which has a cutting profile tool for radial engagement into a workpiece, the one axis of which is in the rotational axis of the cutting head, wherein cutting head and workpiece are moved axially and in the rotational direction with respect to each other, wherein the cutting insert is detachably attachable on a holding element of the cutting head, wherein further the holding element and with it the cutting insect is radially movable between a working position and a releasing position, and with locking means for positioning the cutting insert in the working position and shifting means for shifting the cutting insert from the working position into the releasing position and vice versa, wherein the cutting insert has an axis which runs parallel to the rotational axis in a distance, the cutting insert is attachable on the holding element in at least two rotational positions in an angular distance when it is rotated around its axis, and in every rotational position, a cutting profile tool is in the working position on the cutting insert.
