A hand router has a housing (12) and a tool (22) situated in the housing in a rotary drivable fashion, which it is possible to operate in the intended manner by means of a suction air flow, in particular by means of a vacuum cleaner. The hand router is particularly powerful because a radial turbine wheel (32) equipped with intake and outlet gratings (44, 48) is used as the drive. The housing (12) is made up of tube-like sections (13, 14, 15), in particular that can be grasped by an operating hand, which it is possible to connect with one another by means of flanges (36, 38).

What is claimed is: 1. A hand router (10), comprising: a housing (12); a tool (22) attached to the housing in a rotary drivable fashion, said tool being parallel to a longitudinal axis of the housing (12), wherein the tool is a drill bit or router bit operable for cutting or routing with means for

What is claimed is: 1. A hand router (10), comprising: a housing (12); a tool (22) attached to the housing in a rotary drivable fashion, said tool being parallel to a longitudinal axis of the housing (12), wherein the tool is a drill bit or router bit operable for cutting or routing with means for suction air flow; a drive disposed within the housing, wherein a suction air-drivable turbine with a radial or Pelton turbine wheel (32) is used as the drive within the housing (12), wherein said turbine is provided with means for calming air flowing in said turbine wheel (32) or flowing out of said turbine wheel (32), whereby the means for calming air are comprised of an inlet and an outlet grating (30, 26), the housing (12) being comprised of a number of tubular parts (13, 14, 15); flange means for connecting said tubular parts with one another, and wherein one of the tubular parts (14) in a lower region of the housing (12) encompasses the tool (22) concentrically, wherein the outlet grating (26) has air-conveying elements (28) configured as curved vanes, and wherein the inlet grating (30) and the outlet grating (26) each are incorporated into a motor housing (13) in a manner that reinforces the housing (12). 2. The hand router as recited in claim 1, wherein the outlet grating (26) is configured as a bearing seat for the turbine wheel (32). 3. The hand router as recited in claim 1, wherein the means for suction air flow is configured so that the suction air flow comprised of low-dust air used for driving the turbine wheel (32) is routed separately from a dust air flow so that dust-laden air sucked from a work piece does not come into contact with moving parts of the hand router or parts of the hand router that convey a driving air. 4. The hand router as recited in claim 1, wherein said housing (12) includes air inlet openings, wherein said air inlet openings are configured to allow air used for driving the turbine wheel (32) to be drawn into the housing (12) toward said turbine wheel (32), wherein said air inlet openings are disposed in the housing at a position above and spaced from the tool (22). 5. The hand router as recited in claim 1, wherein the housing (12) has a radio switch, wherein said radio switch is configured to actuate a counterpart switch, wherein said counterpart switch is configured to switch the means for suction air flow on and off, whereby the hand router is switchable on and off at the same time. 6. The hand router as recited in claim 1, further comprising a switch for adjusting an operating speed of the hand router, wherein said switch for adjusting the operating speed is configured as an operating button coupled to a throttle valve situated in the suction air flow. 7. The hand router as recited in claim 1, wherein the housing has a grip region and means for securing an operating hand against slippage.
