It is proposed that the sawing tool has at least one transition region which is arranged between the at least one connecting region and the at least one functional region and which has, compared with the functional region, an increased bending stiffness in a direction orthogonal and/or parallel to a cutting plane of the saw toothing. The configuration according to the disclosure makes it possible to provide a sawing tool which has an advantageously low total weight while simultaneously having an advantageously high bending stiffness. An energy demand for an electric hand-held power tool, in particular for a battery-operated electric hand-held power tool, can be kept advantageously low. The configuration according to the disclosure makes it possible for the electric hand-held power tool to be operated for an advantageously long period with an unchanged battery capacity. An advantageously long battery life can be achieved. Challenges for the sawing tool are in particular differently designed tool receptacles of the hand-held power tool, different application materials, in particular in relation to acting cutting forces and/or torques, a permissible moment of inertia and/or an increase of moments of inertia due to carbide strips of teeth. The sawing tool is preferably configured as a jigsaw blade or as a multifunctional-tool saw blade, in particular as what is known as an OMT saw blade (oscillation multi-tool saw blade). However, in principle, the sawing tool could also be configured as some other saw blade that appears suitable to a person skilled in the art, in particular as a reciprocating saw blade. The sawing tool is preferably provided for use in a jigsaw, in particular a pendulum action jigsaw, or in a multifunctional tool that is driven in an oscillating manner. The term “provided” is intended to mean, in particular, specifically designed and/or specifically equipped. An object being provided for a particular function is intended to mean, in particular, that the object performs and/or carries out this particular function in at least one use state and/or operating state. The main body is preferably fixed to the connecting part by means of a force-fitting, form-fitting and/or materially bonded connection, for example by means of a welded connection, by means of an embossed connection, by means of an adhesive connection or by means of a toothing. The connecting part is preferably in the form of a shank, in particular when the sawing tool is configured as a jigsaw blade, or in the form of a form-fitting connecting part into which a tool receptacle of the hand-held power tool can be at least partially introduced, in particular when the sawing tool is configured as an OMT saw blade. Preferably, the connecting part is at least provided to introduce at least one force and/or at least one torque into the sawing tool. In at least one configuration, in particular when the sawing tool is configured as a jigsaw blade, the connecting part, in particular the shank, is particularly preferably formed integrally with the main body. The term “integrally” is intended to mean, in particular, formed in one piece. Preferably, this one piece is produced from a single blank, a mass and/or a molding. Preferably, the main body has a maximum thickness in particular of at most 2 mm, preferably of at most 1.7 mm, and particularly preferably of at most 1.5 mm.

The saw toothing is preferably formed differently than a serrated edge. The saw toothing is preferably configured as a set saw toothing. However, it is also conceivable for the saw toothing to have some other configuration that appears appropriate to a person skilled in the art and is in particular different than a serrated edge, for example a configuration as a milled and ground saw toothing, as a cross-ground saw toothing, as a riff saw toothing, as a knife saw toothing, as an undulating flat grind with a spacing, in particular independent of a spacing of the reduction grooves, or the like. The saw toothing can be configured in a manner introduced directly into the main body, in particular by milling, grinding or the like, or the saw toothing is configured as a strip of saw teeth which is arranged on the main body by means of a materially bonded connection, for example a welded or soldered connection or the like. It is also conceivable for the saw toothing to have a particle tipping, for example a diamond particle or corundum particle tipping or the like. The saw toothing can be formed from a material that is different than the material of the main body, or the saw toothing is formed from the same material as the main body. The saw toothing can be formed from an HCS (High Carbon Steel), from a bimetal, from a hard metal or a combination of materials. The saw toothing can be arranged on one side or on both sides of the main body. Preferably, a cutting edge of the saw toothing has, in particular when the sawing tool is configured as an OMT saw blade, a maximum extent along the cutting edge which is greater than a maximum extent of the connecting part in a measuring direction parallel to the cutting edge of the saw toothing. In this case, the main body extends along the cutting edge of the saw toothing in a transverse direction to the cutting edge of the saw toothing by at least 10 mm. Preferably, the main body is of weight-optimized configuration in the functional region.

The term “reduction groove” is intended to define in particular a recess or cutout which is arranged in particular in the main body. Preferably, the reduction grooves have been introduced into the main body by removal of material from the main body. However, it is also conceivable for the reduction grooves to have been introduced into the main body by some other method that appears appropriate to a person skilled in the art, for example by embossing or the like. Particularly preferably, the reduction grooves are arranged on both sides of the main body, wherein reduction grooves are arranged on the flank and further reduction grooves of the sawing tool are arranged on a further flank of the main body. Preferably, the reduction grooves on the flank are arranged in an offset manner relative to the further reduction grooves on the further flank. Preferably, the main body is at least partially configured in a wedge-shaped manner in at least one cross-sectional plane. Particularly preferably, the main body at least partially has a clearance angle edge. As a result, the main body can be produced in an advantageously cost-effective manner.

Preferably, in the functional region, the main body has an angled flank portion of the flank. Preferably, in the functional region, the main body has an angled further flank portion of the further flank. The angled flank portion of the flank is preferably introduced into the main body by removal of material, in particular by grinding. The angled further flank portion of the further flank is preferably introduced into the main body by removal of material, in particular by grinding. In principle, the functional region can be provided so as to provide a particularly smooth surface of the main body. As a result, friction and thus heat input into the sawing tool can be kept advantageously low. In principle, the functional region can be provided so as to provide a particularly rough surface of the main body. As a result, an areal removal of material on a workpiece, for example in a grinding manner, can be achieved in addition to a sawing function. In principle, the sawing tool may also have at least one aperture which is arranged on the main body and in the functional region and which is in particular in the form of a through-opening, and/or at least one groove which is arranged on the main body. Preferably, the cutting plane is configured as a main extent plane of the main body, in particular in the functional region. A “main extent plane” of a structural unit is intended to mean in particular a plane which is parallel to the greatest side surface of the smallest imaginary cuboid that only just completely encloses the structural unit, and which runs in particular through the center of the cuboid.

The transition region is preferably formed differently than a machine interface, in particular a shank. The connecting part is preferably configured in a cranked manner when the sawing tool is configured as an OMT saw blade. A different height and/or width of a cranked formation of the connecting part and/or a different connection of the connecting part to the main body advantageously makes it possible to provide an application-adapted sawing tool, in particular for abrasive materials or metals. It is conceivable for a cutting force of in particular 30 N to be applied in the case of abrasive materials, whereas a cutting force of in particular 100 N is applied in the case of metals. In this case, the relatively high cutting force in the case of metals gives rise in particular to a high level of friction, which leads to high torques. Preferably, the sawing tool, in particular the main body and/or the connecting part, has a coating which is in particular at least partially formed from AlTIN (3500±500 HV0.05). For metal applications, the sawing tool is preferably at least partially formed from a hard metal (HM) having a high fracture toughness. Preferably, a tooth spacing for metal applications is at least 1.2 mm. A “tooth spacing” is intended to mean, in particular, a spacing between adjacent teeth of the saw toothing. For abrasive applications, the sawing tool is preferably at least partially formed from a hard metal (HM) having a high hardness. Preferably, a tooth spacing for abrasive applications is at most 1.2 mm.

Furthermore, it is proposed that a maximum thickness of the main body in the at least one transition region corresponds at most to a maximum thickness of the connecting part. This configuration makes it possible to achieve an advantageously low total weight of the sawing tool. As a result of the configuration, an advantageously collision-free movement of the sawing tool relative to the hand-held power tool is made possible. A “thickness” is intended to mean, in particular, a material thickness of the main body, wherein the material thickness corresponds in particular to the smallest edge length of the smallest imaginary cuboid that only just completely encloses the main body. The thickness preferably extends orthogonally with respect to the cutting plane. Preferably, the maximum thickness of the connecting part is at least as great as the maximum thickness of the main body in the transition region. Particularly preferably, the maximum thickness of the main body in the at least one transition region is equal to the maximum thickness of the connecting part.

It is also proposed that the ratio of a maximum longitudinal extent of the transition region to a maximum longitudinal extent of the functional region is less than 1. This configuration makes it possible to achieve an advantageously high bending stiffness of the sawing tool with an advantageously low total weight of the sawing tool. Preferably, the ratio is in particular less than 0.5, preferably less than 0.2, and particularly preferably less than 0.1. Particularly preferably, the ratio is 4 mm/73 mm. Particularly preferably, the maximum longitudinal extent of the transition region is, in particular at least, 4 mm, in particular independently of a maximum longitudinal extent of the sawing tool. Particularly preferably, the maximum longitudinal extent of the functional region is, in particular at most, 73 mm. Preferably, a maximum longitudinal extent between an end of the functional region facing away from the connecting region and an end of the transition region facing toward the connecting region is, in particular at most, 77 mm. Particularly preferably, the sawing tool has a maximum longitudinal extent of 100 mm. Alternatively, the sawing tool may also have some other maximum longitudinal extent that appears suitable to a person skilled in the art, for example 82 mm, 91.5 mm, 100.4 mm, 152 mm, 180 mm or 250 mm. Preferably, the connecting part in the form of a shank is configured as an, in particular simple, T shank. In principle, the connecting part in the form of a shank may also have a shape other than a T shape. Preferably, the connecting part in the form of a shank has a shank length of 22 mm. In principle, the connecting part in the form of a shank may also have some other shank length that appears appropriate to a person skilled in the art.

It is also proposed that the maximum longitudinal extent of the transition region corresponds to at most 50% of a maximum longitudinal extent of a cutting region of the main body, wherein the transition region is at least partially arranged in the cutting region. This configuration makes it possible to achieve an advantageously high bending stiffness of the sawing tool, the sawing tool advantageously being configured in a weight-optimized manner. The maximum longitudinal extent of the transition region corresponds in particular to at most a third, preferably at most 20%, and particularly preferably at most 10%, of the maximum longitudinal extent of the cutting region. Particularly preferably, the maximum longitudinal extent of the transition region corresponds to at least 5% of the maximum longitudinal extent of the cutting region. Preferably, the cutting region is configured over the entire extent of the saw toothing. Preferably, the saw toothing is arranged completely in the cutting region. The saw toothing preferably has a maximum longitudinal extent which corresponds to the maximum longitudinal extent of the cutting region. Particularly preferably, the maximum longitudinal extent of the cutting region corresponds to a sum of the maximum longitudinal extent of the transition region and the maximum longitudinal extent of the functional region.

Furthermore, it is proposed that a maximum longitudinal extent of the transition region is less than 38.5 mm. This configuration makes it possible to provide an advantageously high bending stiffness of the sawing tool in a small region. This configuration makes it possible to keep the total weight of the sawing tool advantageously low. The maximum longitudinal extent of the transition region is in particular at most 20 mm, preferably at most 10 mm, and particularly preferably at most 5 mm. The maximum longitudinal extent of the transition region is in particular at least 15 mm, preferably at least 10 mm, and particularly preferably at least 4 mm.

It is also proposed that, at an end of the main body facing away from the saw toothing, the main body has a thickness, in particular due to removal of material, which corresponds at most to the maximum thickness of the main body in the at least one transition region, wherein the thickness at the end of the main body decreases toward an end of the main body facing away from the connecting region. This configuration makes it possible for the bending stiffness of the sawing tool in the functional region to be increased in an advantageously continuous manner in the direction of the transition region. As a result, the total weight of the sawing tool in the functional region can be kept advantageously low. Preferably, the sawing tool has a lower bending stiffness at the end facing away from the connecting region than at the end of the transition region facing away from the connecting region. Preferably, the bending stiffness runs in an at least substantially linear manner in a direction orthogonal to the cutting plane of the saw toothing between the end facing away from the connecting region and the end of the transition region facing away from the connecting region. The expression “at least substantially” is intended to mean, in particular, that a deviation from a predefined value is in particular less than 25%, preferably less than 10%, and particularly preferably less than 5%, of the predefined value. Preferably, a clearance angle at the flanks of the main body tapers starting from the transition region as far as the end of the main body facing away from the connecting region.

It is also proposed that the sawing tool has at least one elevation which is generated in particular by removal of material on the main body in the at least one functional region and which runs at least substantially parallel to a cutting edge of the saw toothing. This configuration makes it possible to achieve an advantageously high bending stiffness of the sawing tool in the functional region. As a result, the bending stiffness can be increased in a punctiform manner on the main body. Preferably, the at least one elevation has a main extent axis. The main extent axis of the at least one elevation preferably runs at least substantially parallel to the cutting edge of the saw toothing. The at least one elevation is preferably configured as a web. The at least one elevation is in particular provided for increasing the bending stiffness in the direction orthogonal to the cutting plane of the saw toothing. The at least one elevation is preferably arranged within a reduction groove.

Furthermore, it is proposed that, at an end of the at least one transition region facing away from the saw toothing, the at least one transition region has a maximum thickness, in particular 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 saw toothing. This configuration makes it possible to keep the total weight of the sawing tool advantageously low. A contour which advantageously protects the material can be provided on the main body, as a result of which a longevity of the sawing tool is achieved. This configuration makes it possible for the sawing tool to slide over at least one guide roller of the hand tool, in particular of the jigsaw, in an advantageously simple and collision-free manner. Preferably, the main body has at least one shoulder and/or at least one bevel at the end of the at least one transition region facing away from the saw toothing. The at least one shoulder and/or the at least one bevel is in particular provided for guiding the sawing tool on the at least one guide roller of the hand tool, in particular of the jigsaw. Particularly preferably, the maximum thickness of the main body in the at least one transition region at the end of the at least one transition region facing away from the saw toothing is preferably at most 1.5 mm, and particularly preferably at most 1.7 mm.

It is also proposed that the main body is formed from an alloy, which comprises at least heat-treatable steel and nickel. This configuration makes it possible to achieve an advantageously high bending stiffness of the sawing tool. This configuration makes it possible to achieve an advantageously high breaking strength of the main body. The main body is preferably heat-treated. As a result, the material properties of the main body with regard to a high bending stiffness can be advantageously influenced. The main body is preferably manufactured from a sheet metal. The sheet metal is preferably in the form of a strip material. A method for producing a sawing tool is also proposed. By means of the configuration according to the disclosure, it is advantageously possible to produce a sawing tool with a low total weight, in particular a sawing tool that is light compared with a sawing tool without reduction grooves. As a result, it is possible to provide a sawing tool which has an advantageously low total weight while simultaneously having an advantageously high bending stiffness. Particularly preferably, a blank of the main body is punched out of a sheet metal in at least one method step. In principle, the blank may be shaped subsequently or at the same time in a shaping process. Preferably, in at least one method step, at least one reduction groove, in particular all the reduction grooves, is/are introduced as a result of a material-removing machining process, for example grinding, milling or the like. Preferably, in at least one method step, the material thickness in the functional region is reduced as a result of a material-removing machining process, for example grinding, milling or the like. Alternatively or in addition, in at least one method step, the main body in the functional region is processed by embossing. Furthermore, in at least one method step, the main body in the functional region is alternatively or additionally processed as a result of a material-applying processing process, in particular additively by means of a 3D printing process, in particular to increase the bending stiffness.

It is not the intention here for the sawing tool according to the disclosure and/or the method according to the disclosure to be limited to the use and embodiment described above. In particular, the sawing tool according to the disclosure and/or the method according to the disclosure may, in order to perform a function described herein, have a number of individual elements, components and units, and method steps, that deviates from a number stated herein. Furthermore, where value ranges are stated in this disclosure, it is also the intention for values lying within the stated boundaries to be disclosed and usable as desired.
