Appts. has a frame with separate, vertically adjustable table frames and a vertically swingable, circulating cutting tool. The frame has, to swing the cutting tool by 0 - 180 degrees, an electric motor with a flanged-on, eccentric disc, which is power connected with the cutting tool housing lying above the plates via a connecting rod and a rod with a toothed section arranged on the pivot bearing. On the side of the frame opposite the motor is arranged a pair of rods, one being connected with the pivot bearing or the housing so that, during the swinging of the housing and the cutting tool around the pivot bearing, a plate lying between the table frames can be lifted and moved backwards or forwards to provide the square or rectangular material section at a radius of 3 degrees - 20 degrees.
