Abstract: A wood-planing and finishing machine in which a cutting tool is secured to a knife stock through a mounting plate. The mounting plate is mounted on the inclined mounting surface of the knife stock in such a manner that the tilting angle of the former, and therefore its vertical position, can be adjusted by means of a wedge member. The degree of projection of the tool increases when the upper end of the mounting plate is tilted upwardly, and decreases when it is tilted downwardly. The mounting plate is secured by the wedge member against tilting and vertical movements resulting from a resisting force acting on the tool during operation.
