Abstract

A sawing tool, in particular a saw blade, includes: at least one connection region, in particular a shaft, for forming a connection to a tool holder of a hand-held power tool; at least one main body, in particular a carrier, which is connected to the connection region and is designed in one piece; at least one set of saw teeth which is located on the main body; and a plurality of reduction grooves which are located on the main body, in particular introduced into the main body by removing material, and which have a main extension running transversely to a cutting edge of the saw teeth. The reduction grooves extend at least over more than 50% of a total transverse extent of at least one flank of the main body from the cutting edge towards a rear side of the main body, the rear side facing away from the saw teeth.

First claim

1 . A sawing tool, having comprising:
at least one connecting region configured to connect to a tool receptacle of a portable power tool; and at least one main body connected to the at least one connecting region, said at least one main body having at least one saw toothing arranged on the main body and having a multiplicity of reduction grooves arranged on the main body, said multiplicity of reduction grooves having a main extent extending transversely to a cutting edge of the saw toothing, wherein the reduction grooves extend in the direction of a rear side facing away from the saw toothing of the main body at least over more than 50% of a total transverse extent of at least one flank of the main body.

2 . The sawing tool as claimed in claim 1 , wherein the main body has at least one web bordering at least one of the reduction grooves said web extending starting from a saw-tooth root of the saw toothing in the direction of the rear side at least over more than 50% of the total transverse extent of the at least one flank of the main body.

3 . The sawing tool as claimed in claim 1 , wherein the main body has at least one web bordering at least one of the reduction grooves, said web being set back with regard to a tooth tip of the saw toothing in the direction of the flank.

4 . The sawing tool as claimed in claim 1 , wherein the reduction grooves are arranged on both sides of the main body, wherein reduction grooves are arranged on the flank and further reduction grooves are arranged on a further flank of the main body.

5 . The sawing tool as claimed in claim 4 , wherein the reduction grooves on the flank are arranged in an offset manner relative to the further reduction grooves on the further flank.

6 . The sawing tool as claimed in claim 1 , wherein at least two saw teeth of the saw toothing are assigned to one of the reduction grooves.

7 . The sawing tool as claimed in claim 1 , wherein the reduction grooves, as seen along a longitudinal extent of the main body have different maximum main extents.

8 . The sawing tool as claimed in claim 1 , wherein the reduction grooves, as seen along a longitudinal extent of the main body have different maximum transverse extents.

9 . The sawing tool as claimed in claim 1 , wherein the main body has at least one material-free region in particular in addition to the reduction grooves.

10 . (canceled)

11 . The sawing tool as claimed in claim 1 , wherein the sawing tool is a saw blade.

12 . The sawing tool as claimed in claim 1 , wherein the at least one connecting region includes a shank.

13 . The sawing tool as claimed in claim 1 , wherein the at least one main body is formed integrally with the connecting region.

14 . The sawing tool as claimed in claim 1 , wherein the multiplicity of reduction grooves arranged on the main body are introduced into the main body by material removal.

15 . The sawing tool as claimed in claim 1 , wherein the multiplicity of reduction grooves extend starting from the cutting edge in the direction of the rear side facing away from the saw toothing of the main body at least over more than 50% of the total transverse extent of at least one flank of the main body.
