A hand plane, especially a hand plane machine, is provided with an adjusting and indicating arrangement for the planing depth. A wedge which is located before the tool element of the hand plane machine is adjustably fixed to an inclined base surface of the housing and constitutes the contact surface of the hand plane machine. A part of the wedge projects beyond the forward edge of the housing and is provided at its upper side with a scale. By means of the housing edge, the displacment of the wedge and consequently the adjustment of the planing depth can be read from the scale. The hand plane is of simple structure and good stability with respect to the adjustment, wherein the wedge can be fastened to the housing for example through screwing.
An electric hand plane has a wedge-shaped body having a lower wedge surface adapted to rest on a workpiece and an upper wedge surface, a plane housing supported on the upper wedge surface of the wedge-shaped body and having a counter-surface, a device for producing a clamping force between the upper wedge surface of the wedge-shaped body and the counter-surface of the housing, and a single handle operative for cancelling the clamping force during an adjustment and also for displacement of the wedge-shaped body, and a gear mechanism means arranged so that the handle displaces the wedge-shaped body relative to the plane housing via the gear mechanism means by rotation.
