A milling cutter for a wood operating machine has pairs of base plates, (20) each plate having a recess (50) to received a reducing insert. Each pair of base plates is mounted on a guide plate (24), and numerous such guide plates are installed on a common tubular shaft (10). Each foundation plate has a planetary gearbox toothed rack. The toothed racks of each pair of foundation plates engage a common pinion (84) mounted on the tubular shaft. The radial distance of each foundation plate is modified by a screw and the racks and pinion ensure that the radial adjustment is usually exactly the same for each person in the same pair of base plates.
