Parting tool

1. A parting tool, comprising:

a carrier blade having a receiver for fixing to a tool spindle of a power tool that is configured for being driven oscillatingly about a longitudinal axis of said tool spindle, said carrier blade further having a toothing portion carrying a finite, geometrically determined toothing, wherein said toothing is disposed at a distance from said receiver at one end of said carrier blade and is configured to be advanced perpendicularly in relation to the longitudinal axis;

wherein said toothing is configured in a non-uniform manner along the toothing portion, the toothing portion comprising a middle region and two end regions adjoining said middle region, each of said end regions comprising strengthened corner teeth, wherein said strengthening of said corner teeth is effected by at least one feature selected from the group consisting of a tooth depth, a tooth pitch, a transition flank, a tooth tip, a tooth gullet, said feature being different from a corresponding feature provided on said middle region so as to strengthen said corner teeth;

said toothing is configured substantially straight;

said toothing having tooth depth comprises rounded tooth gullets having radii being smaller in said middle region than in said end regions; and

said corner teeth have a tooth depth being smaller than a tooth depth of adjacent teeth of the toothing; and

said toothing portion further has a variable tooth pitch, said middle region having a larger tooth pitch than a tooth pitch of said end regions.

2. The tool of claim 1 , wherein said toothing portion has a variable tooth pitch, said middle region having a larger tooth pitch than a tooth pitch of said end regions.

3. The tool according to claim 1 , wherein said toothing portion has a variable tooth pitch, said middle region having a smaller tooth pitch than a tooth pitch of said end regions.

4. The tool according to claim 1 , wherein said corner teeth are provided with transition flanks, said transition flanks being flatter than flanks provided on adjacent teeth.

5. The tool according to claim 1 , wherein said corner teeth have tooth tips that are configured broader than tooth tips provided on adjacent teeth.

6. The tool according to claim 1 , wherein said toothing has a set.

7. The tool according to claim 1 , further comprising an offset between said receiver and said toothing portion.

8. The tool according to claim 7 , wherein said receiver and said toothing portion both comprise flat parts extending in parallel but offset from each other.

9. The tool according to claim 1 , wherein said receiver comprises a positive-closure element mated to said tool spindle so as to allow a form-fit connection thereto.

10. The tool according to claim 1 , wherein said receiver is configured as a receiving opening configured for fitting onto said drive spindle.

11. The tool according to claim 1 , wherein said carrier blade is composed of a plurality of metal components secured one to another.

12. The tool according to claim 1 , wherein said toothing comprises a coating configured for at least increasing strength or minimizing wear.

13. The tool according to claim 1 , wherein said toothing of said toothing portion is configured substantially arcuate.

14. A parting tool, comprising:

a carrier blade having a receiver for fixing to a tool spindle of a power tool that is configured for being driven oscillatingly about a longitudinal axis of said tool spindle, said carrier blade further having a toothing portion carrying a finite, geometrically determined toothing, wherein said toothing is disposed at a distance from said receiver at one end of said carrier blade and is configured to be advanced perpendicularly in relation to the longitudinal axis;

wherein said toothing is configured in a non-uniform manner along the toothing portion, the toothing portion comprising a middle region and two end regions adjoining said middle region, each of said end regions comprising strengthened corner teeth;

said toothing is configured substantially straight;

said toothing having tooth depth comprises rounded tooth gullets having radii being smaller in said middle region than in said end regions said corner teeth have a tooth depth being smaller than a tooth depth of adjacent teeth of the toothing; and

said toothing portion further has a variable tooth pitch, said middle region having a larger tooth pitch than a tooth pitch of said end regions.

15. A power tool comprising a housing, having a tool spindle that can be driven in rotary oscillation about a longitudinal axis thereof and has a fastening for receiving a parting tool, said parting tool comprising:

a carrier blade having a receiver for fixing to said tool spindle, said carrier blade further having a toothing portion carrying a finite, geometrically determined toothing, wherein said toothing is disposed at a distance from said receiver at one end of said carrier blade and is configured to be advanced perpendicularly in relation to the longitudinal axis;

wherein said toothing is configured in a non-uniform manner along the toothing portion, the toothing portion comprising a middle region and two end regions adjoining said middle region, each of said end regions comprising strengthened corner teeth;

said toothing is configured substantially straight;

said toothing having tooth depth comprises rounded tooth gullets having radii being smaller in said middle region than in said end regions said corner teeth have a tooth depth being smaller than a tooth depth of adjacent teeth of the toothing; and

said toothing portion further has a variable tooth pitch, said middle region having a larger tooth pitch than a tooth pitch of said end regions.
