Abstract

The disclosure relates to a sawing tool, in particular a saw blade, comprising: at least one connection part, which at least partly forms a connection region for connecting to a tool receptacle of a hand-held power tool; at least one main body, in particular one single-piece main body, which is connected to the connection part; at least one array of saw teeth, in particular one array of set saw teeth, which is arranged on the main body; and at least one functional region, in particular one reduction groove region, which is arranged on the main body and on which the array of saw teeth is at least partly arranged. According to the disclosure, the sawing tool has at least one transition region, which is arranged between the at least one connection region and the at least one functional region and which has increased flexural stiffness, in comparison to the functional region, in a direction orthogonal and/or parallel to a cutting plane of the array of saw teeth.

First claim

1 . A sawing tool, in particular a saw blade, comprising:
at least one connecting part which at least partially forms a connecting region configured to connect to a tool receptacle of a hand-held power tool; at least one main body which is formed integrally with the connecting part; at least one set saw toothing which is arranged on the at least one main body; and at least one functional region which is arranged on the at least one main body in the form of a reduction groove region on which the at least one set saw toothing is at least partially arranged, wherein at least one transition region is arranged between the at least one connecting region and the at least one functional region and which has, compared with the at least one functional region, an increased bending stiffness in a direction orthogonal and/or parallel to a cutting plane of the at least one set saw toothing.

2 . The sawing tool as claimed in claim 1 , wherein a maximum thickness of the at least one main body in the at least one transition region corresponds at most to a maximum thickness of the at least one connecting part.

3 . The sawing tool as claimed in claim 1 , wherein a ratio of a maximum longitudinal extent of the at least one transition region to a maximum longitudinal extent of the at least one functional region is less than 1.

4 . The sawing tool as claimed in claim 1 , wherein:
a maximum longitudinal extent of the at least one transition region corresponds to at most 50% of a maximum longitudinal extent of a cutting region of the at least one main body; and the at least one transition region is at least partially arranged in the cutting region.

5 . The sawing tool as claimed in claim 1 , wherein a maximum longitudinal extent of the at least one transition region is less than 38.5 mm.

6 . The sawing tool as claimed in claim 1 , wherein:
at an end of the at least one main body facing away from the at least one set saw toothing, the at least one main body has a thickness, due to removal of material, which corresponds at most to a maximum thickness of the at least one main body in the at least one transition region; and the thickness at the end of the at least one main body decreases toward an end of the at least one main body facing away from the connecting region.

7 . The sawing tool as claimed in claim 1 , wherein at least one elevation is generated by removal of material on the at least one main body in the at least one functional region and runs at least substantially parallel to a cutting edge of the at least one set saw toothing.

8 . The sawing tool as claimed in claim 1 , wherein, at an end of the at least one transition region facing away from the at least one set saw toothing, the at least one transition region has a maximum thickness, due to removal of material, which is smaller than a maximum thickness of the at least one transition region at an end of the at least one transition region facing toward the at least one set saw toothing.

9 . The sawing tool as claimed in claim 1 , wherein the at least one main body is formed from an alloy, which comprises at least heat-treatable steel and nickel.

10 . A method for producing a sawing tool, comprising:
forming at least one main body integrally with at least one connecting region; forming at least one set saw toothing on the at least one main body; forming at least one functional region on the at least one main body by removal of material to form a reduction groove region; and forming at least one transition region between the at least one connecting region and the at least one functional region, wherein the at least one set saw toothing is arranged at least partially on the at least one functional region, and the at least one transition region has, compared with the at least one functional region, an increased bending stiffness in a direction orthogonal and/or parallel to a cutting plane of the at least one set saw toothing.
