Abstract

A power cutting tool includes at least one cutting strand, and at least one guide unit that is configured to guide the cutting strand. The power cutting tool further includes at least one coding unit which has at least one coding element that is configured to encode at least one coupling interface of the guide unit.

First claim

The invention claimed is:

1. A power tool system, comprising:
at least one power-tool parting device including:
at least one cutting strand;
at least one guide unit configured to guide the cutting strand and including at least one coupling interface; and
at least one coding unit including at least one coding element configured to code the at least one coupling interface of the guide unit; and

a portable power tool configured to at least one of form-close couple and force-close couple to the at least one power-tool parting device,
wherein the coding element includes an RFID chip.

2. A portable power tool comprising:
a coupling device configured to at least one of form-close couple and force-close couple to a power-tool parting device, said parting device including:
at least one cutting strand;
at least one guide unit configured to guide the cutting strand and including at least one coupling interface; and
at least one coding unit including at least one coding element configured to code the at least one coupling interface of the guide unit,
wherein the coding element includes an RFID chip.

3. A power-tool parting device, comprising:
at least one cutting strand;
at least one guide unit configured to guide the cutting strand and including at least one coupling interface; and
at least one coding unit including, at least one coding element configured to code the at least one coupling interface of the guide unit,
wherein the coding element includes an RFID chip.

4. The power-tool parting device as claimed in claim 3 , wherein, to enable coding the at least one coupling interface, the coding element further includes an extension extending substantially parallelwise in relation to a cutting plane of the cutting strand.

5. The power-tool parting device as claimed in claim 3 , wherein the coding element, as viewed in a cutting plane of the cutting strand, projects axially beyond the guide unit.

6. The power-tool parting device as claimed in claim 3 , wherein the coding element, at least in a partial region, as viewed along a direction that is at least substantially parallel to a cutting plane of the cutting strand, has a greater maximum width extent than at least one of:
a maximum width extent of the guide unit; and
a maximum width extent of the cutting strand.

7. The power-tool parting device as claimed in claim 3 , wherein to enable coding of the at least one coupling interface, the coding element extends at least substantially transversely in relation to a cutting plane of the cutting strand.

8. The power-tool parting device as claimed in claim 3 , wherein the coding element includes an extension that, at least in a partial region, as viewed along a direction that is at least substantially perpendicular to a cutting plane of the cutting strand, has a greater maximum thickness extent than at least one of:
a maximum thickness extent of the guide unit; and
a maximum thickness extent of the cutting strand.

9. The power-tool parting device as claimed in claim 3 , wherein the coding element includes an extension that, at least in a partial region, as viewed along a direction that is at least substantially perpendicular to a cutting plane of the cutting strand, has a lesser maximum thickness extent than at least one of:
the maximum thickness extent of the guide unit; and
the maximum thickness extent of the cutting strand.

10. The power-tool parting device as claimed in claim 3 , wherein the coding element, as viewed in a cutting plane of the cutting strand, extends at least substantially transversely in relation to a central axis of the guide unit.
