A suction device for a power tool (10a, 10b) comprising a dust container (12a-12c); a suction head (14a-14c) to be placed on a work piece (16a-16b), wherein the dust container (12a-12c) is integrated in the suction head (14a-14c); a bearing unit (46a-46c, 48a) by which the suction head (14a-14c) with the integrated dust container (12a-12c) is supportable on a housing (26a-26b) of the power tool (10a, 10b) such that when the bearing unit is fixedly supported on the housing, the suction head (14a-14c) with the integrated dust container (12a-12c) is displaceable relative to the housing along a working direction (24a-24c) of the power tool, and also including a suction duct which directs air flow from the suction head into the housing, and wherein the suction head (14a-14c) includes an opening through which a tool bit (32a, 32b) drivable by the power tool is capable of being guided in at least one operating state of the power tool. 2. The suction device as recited in claim 1, characterized by a suction unit (18a-18b) integrated in the power tool (10a, 10b) for producing a vacuum in the suction head (14a-14c). 3. The suction device as recited in claim 2, wherein the suction device (18a 18b) includes a cooling fan (20a, 20b) of the power tool (10a, 10b). 4. The suction device as recited in claim 1, characterized by an additional unit (22a-22c) that includes the bearing unit (46a-46c, 48a) for supporting the suction head (14a-14c) on a housing (26a, 26b) of the power tool (10a, 10b) and is capable of being detachably retained on the power tool (10a,10b). 5. The suction device as recited in claim 4, wherein the additional unit (22a-22c) is retainable on the power tool (10a, 10b) using a snap-in connection. 6. A suction device as recited in claim 4, wherein a filter (44a) is mounted on said bearing unit (46a, 48a). 7. A suction device as defined in claim 4, wherein the bearing unit is formed by guide rods (46a-46c, 48a). 8. The suction device as recited in claim 1, wherein the bearing unit (46a-46c, 48a) includes a depth stop. 9. The suction device as recited in claim 1, wherein various dimensions can be selected for the opening (30a'-30c') by selecting from replaceable portions of the suction head that have different dimensions. 10. The suction device as recited in claim 1, wherein the opening (30a-30c) forms one end of a funnel-shaped receiving area that tapers in the working direction (24a-24c). 11. The suction device as recited in claim 1, wherein an air stream is capable of being introduced into the dust container (12a) through a duct section (82a) of the suction head (14a) in a circumferential direction of the dust container (12a). 12. A suction device as recited in claim 1, wherein the suction head (14a-14c) has a suction part (34a-34c) which forms a single unit (72a-72c) with the dust container (12a-12c). 13. A suction device as recited in claim 12, further comprising a second unit (22a-22c), wherein said single unit (72a-72c) is detachably retained on said second unit (22a-22c). 14. A suction device as recited in claim 13, wherein said second unit (22a, 22c) is capable of being detachably retained on the power tool (10a, 10b). 15. A suction device as recited in claim 13, wherein said single unit (72a-72c) can be fixed by a snap-in connection (68a) at a side of said second unit (22a-22c) facing the work place. 16. A suction device as recited in claim 12, wherein air and removed material which are suctioned up through openings (30a, 30a-30c) in the suction part (34a-34c) are introduced perpendicularly to the working direction (24a) via a duct section (82a) into the dust container (12a-12c). 17. A suction device as recited in claim 1, wherein the suction head (14a-14c) has a suction part (34a-34c) which forms with the dust container (12a-12c) a one-piece unit. 18. A suction device as recited in claim 1; further comprising connecting means for removably connecting the suction head with the integrated dust container to the bearing unit. 19. A suction device as defined in claim 18, wherein said connecting means comprise a lever with a hook. 20. A suction device as defined in claim 1, and further comprising connecting means for removably connection the suction head with the integrated dust container to the suction duct.
