Abstract

A hand-held power tool includes an SDS tool receiver and a tool housing. The SDS tool receiver includes at least one vacuuming-off channel and is configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece. The tool housing includes at least one drive unit configured to drive the exchangeable insert tool.

Claims

1. A hand-held power tool, comprising:

an SDS tool receiver including at least one vacuuming-off channel and configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece; and

a tool housing including at least one drive unit configured to drive the exchangeable insert tool.

2. The hand-held power tool as claimed in claim 1, wherein the SDS tool receiver further includes a receiver housing that defines the at least one vacuuming-off channel.

3. The hand-held power tool as claimed in claim 1, wherein:

the SDS tool receiver further includes a closure element and a main body that is adjustable between an open position and a closed position via the closure element; and

the main body is connected to the tool housing, formed onto the tool housing, or integral with the tool housing.

4. The hand-held power tool as claimed in claim 3, further comprising a clamping device disposed within the main body and configured to clamp the exchangeable insert tool.

5. The hand-held power tool as claimed in claim 3, wherein the at least one vacuuming-off channel is at least partially defined by at least one of:

(i) the main body and (ii) the closure element.

6. The hand-held power tool as claimed in claim 3, wherein:

the main body includes at least one first flute-type channel;

the closure element includes at least one second flute-type channel; and

in the closed position of the main body, the first flute-type channel and the second flute-type channel define the at least one vacuuming-off channel.

7. The hand-held power tool as claimed in claim 3, wherein the closure element includes a locking element configured to lock the closure element to the main body.

8. The hand-held power tool as claimed in claim 7, wherein the locking element includes at least one latching element and is configured to latch onto the main body.

9. The hand-held power tool as claimed in claim 7, wherein:

the locking element is configured to connect to the main body via a screw connection; and

the main body includes at least one screw thread.

10. The hand-held power tool as claimed in claim 3, wherein the closure element is pivotably mounted on the main body.

11. The hand-held power tool as claimed in claim 1, wherein the at least one vacuuming-off channel is has a tubular shape.

12. The hand-held power tool as claimed in claim 1, further comprising a vacuuming-off connection piece connected to the at least one vacuuming-off channel and configured to connect to an external vacuuming-off system.

13. The hand-held power tool as claimed in claim 1, wherein the SDS tool receiver is further configured to receive an exchangeable insert tool that has a cutting strand configured to revolve around an assigned guide unit.

14. The hand-held power tool as claimed in claim 1, wherein the hand-held power tool is a chain saw.

15. An SDS tool receiver comprising at least one vacuuming-off channel and configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece.
