Beschreibung
Zusammenfassung:	A hand held power tool includes: a motor room housing a motor that drives an output shaft; a bevel gear including interconnected pinion and crown gears, wherein the pinion gear is connected to a pinion shaft drivingly connected to the output shaft and the crown gear is drivingly connected to a tool holding shaft; a gear housing that delimits a fluid tight gear space around the bevel gear; a bearing, around the pinion shaft and close to the pinion gear, which delimits a confined space around the pinion shaft and within the gear space; and a fluid tight axial sealing, around the pinion shaft inside the confined space of the gear space, which seals off the gear space from the motor room. At least one fluid conveying opening is arranged to put the confined space of the gear space in fluid contact with the rest of the gear space.
