Eine Handwerkzeugmaschine mit einem Gehäuse (12) und einem daran drehend und/oder schwingend antreibbar angeordneten Werkzeug (70), das mittels eines Saugluftstromes, insbesondere mit einem Staubsauger, bestimmungsgemäß betreibbar ist, wird dadurch besonders effektiv, dass als Antrieb eine Turbine (36) mit Turbinenrad (38) dient, die mit Mitteln zum Beruhigen der ein- bzw. ausströmenden Luft, insbesondere mit Vorleitgitter (74) und/oder Nachleitgitter, versehen ist, wobei der das Turbinenrad (38) anströmende Luftstrom in einem spitzen Winkel zur Hochachse (40) des Turbinenrads (38), insbesondere unter 50 DEG weitergeführt bzw. umgelenkt wird. A hand-held power tool, having a housing (12) and a tool (70) which is located on the housing in a way drivable to rotate and/or oscillate and is drivable as intended by means of a flow of suction air, especially with a vacuum cleaner, is made especially effective in that a turbine (36) with a turbine wheel (38) serves as the drive mechanism and is provided with means for calming the inflowing and outflowing air, in particular with an upstream baffle (74) and/or a downstream baffle, and the air flow approaching the turbine wheel (38) is carried onward or deflected at an acute angle to the vertical axis (40) of the turbine wheel (38), in particular an angle of less than 50°.
