What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims: 1. A dust catcher comprising a contact element configured to catch abraded material that is produced by a power tool during operation on a workpiece, said contact element comprising a guide device for guiding the power tool for operation on the workpiece, the contact element forming a housing that encloses a dust container and having an aspiration area and a suction extraction area, both of the aspiration area and suction extraction areas having contact surfaces for resting upon the workpiece, and a hand grip connecting the aspiration area and the suction extraction area, the hand grip forming a gap with the workpiece, the gap being of a sufficient size for an operator's finger to wrap around the handgrip. 2. A dust catcher comprising a contact element configured to catch abraded material that is produced by a power tool during operation on a workpiece, said contact element comprising a guide device for guiding the power tool for operation on the workpiece, the contact element forming a housing that encloses a dust container, and comprises an upper opening and a lower opening through which a drill bit of said power tool is passed, the contact element having an aspiration area adjacent the upper and lower openings and a suction extraction area, both of the aspiration area and suction extraction areas having contact surfaces for resting upon the workpiece, and a hand grip connecting the aspiration area and the suction extraction area, the hand grip forming a gap with the workpiece, the gap being of a sufficient size for an operator's finger to wrap around the handgrip. 3. The dust catcher as set forth in claim 1, wherein said contact element further includes a, telescoping rod and a ring embracing the telescoping rod that acts as a depth stop. 4. A dust catcher as defined in claim 1, wherein said contact element has at least one connection means for connecting a vacuum cleaner. 5. A dust catcher as defined in claim 1, wherein said contact element includes a unit which is configured for visualizing a working point of the power tool. 6. A dust catcher as defined in claim 1; and further comprising a measurement unit for determining a spacing of a working point of the power tool from a characteristic feature of the workpiece. 7. A dust catcher as defined in claim 2, wherein the upper opening comprises a sealing lip of rubber. 8. A dust catcher as defined in claim 1, wherein said contact element includes an inclination sensor unit for detecting a rotary position of said contact element. 9. A dust catcher as defined in claim 1, wherein said contact element has one contact face provided with at least one nonslip liner. 10. A dust catcher as defined in claim 1, wherein said handgrip element has a curved surface ergonomically adapted to a palm of a hand. 11. A dust catcher as defined in claim 1, wherein said contact element has an edge configured to be overlapped by a user's hand. 12. A dust catcher as defined in claim 2, wherein the upper opening and the lower opening each have a diameter large enough for said drill bit to pass. 13. A guide device as defined in claim 1; and further comprising a spring mechanism for generating a contact pressure of said contact element on the workpiece. 14. A guide device as defined in claim 1; and further comprising a depth stop for limiting a freedom of motion of the power tool in a working direction. 15. The dust catcher as defined in claim 6, wherein the measurement unit is embodied as a laser distance measuring device. 16. The dust catcher as defined in claim 9, wherein the at least one nonslip liner comprises several rubber cushions. 17. The dust catcher as defined in claim 7, wherein the sealing lip of rubber of the upper opening is configured to cause an underpressure to draw air into the lower opening. 18. The dust catcher as defined in claim 1; and further comprising a unit for illuminating a work area of the power tool embodied as a light-emitting diode with a lens system.
