As a result, an optimum suction effect is also achieved there, if advantageously e.g. a vacuum cleaner is connected to the dust discharge port.
- the dust removal, in particular a suction so it is optimal even in areas of the tool room, which are far away from the inlet opening.
- the flow cross section may increase, for example, in stages. However, it is advantageous if the flow cross-section increases substantially continuously. It is possible that the flow cross-section increases linearly. But it is also possible that the flow cross section in the direction of the inlet opening is not linear, for example exponentially, to.
- the tool has on its side facing the dust removal channel wings or other air entrainment means for generating or accelerating the air flow. As a result, the tool can still contribute to a greater extent to the flow in the dust discharge channel.
- the top wall is advantageously substantially flat. This creates a good flow behavior. It is understood that the respective walls can also have, for example, air guide ribs, channels or the like.

- the cover wall 36 is expediently flat, which allows optimum flow behavior.
- the dust removal channel 62 is limited by the side wall / peripheral wall 38. However, there is a gap between the peripheral wall 38 and the side edge 28 of the tool 21 through which air can flow into the dust discharge channel 62. This inflowing air flows through the air-permeable seal 48, in this case the brush 49, through and past the lower end side of the side wall / peripheral wall 38 into the dust discharge channel 62.
- the air passage openings 66 are provided on the tool 21, through which air can flow into the dust discharge channel 62.

- a rotational direction of the tool 21 corresponds to a flow direction of the dusty air flow 65, which increases its flow.
- the dust air flow 65 is shown as an arrow indicating the flow direction of the dust air flow 65.
- the cover wall 36 may advantageously be a plate component, for example of plastic, which is screwed to the inside to form an upper wall of the tool space 26 to the hood body.
- the cover wall 36 may also form an integral part of the hood body 29.
- the seal 48 or brush 49 is permeable to air. This makes it possible that supply air 67 through the bristles of the brush 49 can flow and past the front, free side of the peripheral wall 38 in the dust discharge channel 62, said supply air flows into the annular gap between the peripheral wall 38 and the side edge of the tool 21 and through the air passage openings 66 on the tool 21.
- the peripheral wall 38 is advantageous in this innovative concept insofar as it laterally delimits the dust removal channel 62 and thus enables optimum flow in the direction of the inlet opening 63.
- the supply air 67 can still flow freely, so that no flow-preventing negative pressure is created.
