A portable power tool, in particular a hand-held planing machine, includes at least one workpiece contact unit and at least one handle unit. The workpiece contact unit has at least one workpiece contact surface, and the handle unit has at least one main handle. The main handle has at least one maximum distance point that, in a direction extending at least substantially perpendicularly to a workpiece contact surface, has a maximum distance from the at least one workpiece contact surface. The maximum distance is less than 150 mm.

The invention provides a hand held planer (1) for planing a work piece surface comprising a planing tool (41) disposed between a first base (20) and a second base (30,31), the planer (1) being configurable so that it can be moved by hand along the work piece surface with the first base (20) leading and the first (20) and second (30,31) bases guiding the planer (1) along the work piece surface and the planing tool planing off a thickness of the work piece, wherein at least one (30,31) of the bases is an adjustable base such that at least a portion (31) thereof is removable or movable between a position that provides an operable lengthened configuration and a position that provides an operable shortened configuration such that a length of the adjustable base in guiding contact with the work piece surface is reduced or eliminated in the shortened configuration compared to the lengthened configuration.

A power planer includes a casing, a motor having rotation shaft, a power supply portion for supplying electric power to the motor, a control portion, a cutter block, and a fan. The casing has intake and discharge openings and provides an air passage from the intake opening to the discharge opening. The control portion is connected to the electric motor and to the power supply portion. The cutter block has an axis parallel to the rotation shaft, and is supported to the casing and rotatable about the axis. A blade is provided in the cutter block. The fan is provided in the casing and configured to generate air stream within the casing and flowing along the air passage in a flowing direction. The air passage includes a control portion cooling passage for cooling the latter. The fan is positioned downstream of the control portion in the flowing direction.

A portable planing machine has a rotatably mounted planing shaft in a housing. The planing shaft is driven by a drive motor. Furthermore, a fan wheel is configured to generate a cooling airflow. At least one cooling duct is integrated into the planing shaft. An outflow opening of the cooling channel is at a greater radial spacing from the rotational axis than an inflow opening of the cooling duct.
