Planing head consists of a body connected to slides movable relative to the body, to the front vertical surface of which a hinged board with a cutter holder is connected by means of a rotary joint. A second hinged board with a second cutter holder is connected to the rear vertical surface of the slides by means of a second rotary joint, which is mirror-symmetrical to the hinged board with a cutter holder connected to the front vertical surface of the slides.
