The plane head for the hand-held planing machine includes a cylindrical base body (11) made from a group of identical stamped sheets (18) arranged axially next to each other and each provided with a punched hole (150) so as to form a base body cavity (15); a planing knife (14) protruding radially beyond an outer surface of the base body (11) from a longitudinal groove (13) and fixed therein by a form-fitting connection or form-locking connection so that the planing knife cannot be radially dislodged from the base body; and a chuck wedge (16) received in the base body cavity (15) so that the planing knife (14) is clamped in the base body (11) by centrifugal force during rotation of the plane head. To provide strength and safety from action of wood chips the chuck wedge (16) is held releasably, radially movable, in the base body cavity (15), the base body cavity (15) and the chuck wedge (16) are shaped to conform to each other so that the chuck wedge bears with a clamping surface (161) on the planing knife (14) and is braced on opposing surfaces of the base body cavity (15) facing opposite to each other in a rotation direction of the planing head. The chuck wedge (16) is formed so that it is clampable against a bottom surface (152) of the base body cavity (15) to produce a spring force acting on the planing knife. |
