The milling cutter with a feeding motion in forward and reverse mills plane surfaces of large diameter in the area of through holes and consists of a tool head 17 which can be driven in rotation by a shank 17 and in which are mounted two cutting parts so as to be radially movable and lockable in seating slots. The cutting parts are shifted by means of a rocker which is disposed so as to be rotatable about the longitudinal axis of the tool and whose steering bolts attached to its face and pointing in an axial direction engage associated recesses in the cutting parts in the manner of crank pins. |
