ABSTRACT:
This disclosure relates to a planer provided with means for reducing the noise emitted by the blade-retaining shaft. The blades have a cutting edge projecting from the rotary surface of the shaft. Ahead of each blade with respect to the shaft direction of rotation there is arranged a deflecting surface which deflects the air flow over the cutting edge and has a free edge whose distance from the axis of rotation of the blade-retaining shaft is smaller than that of the cutting edge.
