ABSTRACT:
A tool for removing shavings from wood has a rotary main body portion provided with recesses extending inwardly from the peripheral surface and receiving elongated plate-like holders for flat blades made of sheet steel. Each blade is formed with openings for locating pins on the respective holder, and each holder is urged toward an internal surface of the body portion by a spring-biased wedge. Strip-shaped guide members are adjustably connected with the holders and are slidable in grooves machined into the internal surfaces of the body portion. A blade can be removed or inverted by moving the respective wedge away from the holder and by thereupon moving the holder axially of the body portion so that the blade can be lifted off the locating pins. The holders and the guide members have cooperating surfaces along which the holders can slide to thereby move the cutting edges of the blades toward or away from the axis of the body portion.
