The configuration according to the invention provides a saw tool that advantageously has a low overall weight while simultaneously possessing advantageously high bending stiffness. The energy demand for electric hand-held power tools, especially those powered by batteries, can be advantageously kept low. With the configuration according to the invention, electric hand-held power tools can advantageously operate for extended periods while maintaining a constant battery capacity. Advantageously long battery runtime can be achieved. The challenges for saw tools particularly lie in the different configurations of the tool receiver in hand-held power tools, the different application materials (especially concerning the acting cutting force and / or torque), and the permissible moment of inertia and / or the increased moment of inertia due to carbide racks. Preferably, the saw tool is constructed as a trestle blade or as a multi-tool saw blade, especially as a so-called OMT saw blade (Oszillation-Multi-Tool- ). Basically, however, the saw tool can also be configured with other saw blades which appear suitable to the person skilled in the art, for example as a saber saw blade. Preferably, the saw tool is provided for use in a punch saw, in particular a curved punch saw, or in a multi-functional tool which is driven in an oscillating manner. "Provided" is to be understood in particular as being designed in particular and / or equipped in particular. An object is provided for a certain function in particular if the object fulfils and / or implements this certain function in at least one application state and / or operating state. The base body is preferably fixed on the connecting piece by means of a force-locked, form-locked and / or material-locked connection, for example by means of a soldered connection, by means of a swage connection, by means of an adhesive connection or by means of a toothed coupling connection.

The saw teeth can be introduced directly into the base body, in particular by milling, grinding or the like, or the saw teeth are configured as a saw tooth strip which is arranged on the base body by means of a material-locked connection, for example a fusion or brazing connection or the like. Furthermore, it is conceivable for the saw teeth to have a grain loading, for example a diamond grain or corundum grain loading or the like. The saw teeth can be configured from a material which is different from the material of the base body, or the saw teeth are made from the same material as the base body.

Preferably, the saw tool has a multiplicity of relief grooves arranged on the base body, especially introduced into the base body by material removal, which have a main extension running transversely to the cutting edge of the saw tooth, wherein the relief grooves especially extend from the cutting edge at least over more than 50% of the entire transverse extension of at least one side face of the base body in the direction of the end of the base body facing away from the saw tooth. Especially, the term "relief groove" is to be understood as especially a recess or a void arranged on the base body. Preferably, the relief grooves are introduced into the base body by material removal from the material of the base body. However, it is also conceivable that the relief grooves are introduced into the base body by means of other methods which appear meaningful to the person skilled in the art, for example by stamping or the like. Particularly preferably, the relief grooves are arranged on the base body on both sides, wherein a relief groove is arranged on a side face and a further relief groove of the saw tool is arranged on a further side face of the base body.

Due to the different heights and / or widths of the bends in the connector and / or due to the different attachments of the connector to the base, a saw tool that matches the application can be advantageously provided, especially for saw tools for abrasive materials or metals. It is conceivable that in the case of abrasive materials, a cutting force of particularly 30 N is applied, while in the case of metals, a cutting force of particularly 100 N is applied. Here, the relatively high cutting force in the case of metals particularly causes high friction, which leads to high torque.

[0005] It is further proposed that the maximum thickness of the base body in the at least one transition region corresponds at most to the maximum thickness of the connecting piece. With this configuration, an advantageously small overall weight of the saw tool can be achieved. With this configuration, an advantageously collision-free movement of the saw tool relative to the hand-held power tool is achieved. The "thickness" is understood to mean, in particular, the material thickness of the base body, wherein the material thickness corresponds, in particular, to the smallest edge length of an imaginary smallest cuboid that just completely surrounds the base body.

Preferably, the maximum thickness of the connecting piece is at least as great as the maximum thickness of the base body in the transition region. Particularly preferably, the maximum thickness of the base body in the at least one transition region is as great as the maximum thickness of the connecting piece.

[0006] It is further proposed that the maximum longitudinal extension of the transition region has a ratio of less than 1 to the maximum longitudinal extension of the functional region. With this configuration, an advantageously high bending stiffness of the saw tool can be achieved in the case of an advantageously small overall weight of the saw tool. Preferably, this ratio is, in particular, less than 0.5, preferably less than 0.2 and particularly preferably less than 0.1. Particularly preferably, this ratio is 4 mm / 73 mm. Particularly preferably, the maximum longitudinal extension of the transition region is, in particular, at least 4 mm, in particular independently of the maximum longitudinal extension of the saw tool. Particularly preferably, the maximum longitudinal extension of the functional region is, in particular, at most 73 mm. Preferably, the maximum longitudinal extension between the end of the functional region facing away from the connecting region and the end of the transition region facing toward the connecting region is, in particular, at most 77 mm. Particularly preferably, the saw tool has a maximum longitudinal extension of 100 mm. Alternatively, the saw tool can also have other maximum longitudinal extensions that appear suitable to the person skilled in the art, for example 82 mm, 91.5 mm, 100.4 mm, 152 mm, 180 mm or 250 mm.

[0007] It is further proposed that the maximum longitudinal extension of the transition region corresponds to at most 50% of the maximum longitudinal extension of the cutting region of the base body, wherein the transition region is arranged at least partially in the cutting region. With this configuration, a favorably high bending stiffness of the saw tool can be achieved, wherein the saw tool is favorably configured weight-optimized. The maximum longitudinal extension of the transition region in particular corresponds to at most one third, preferably at most 20% and particularly preferably at most 10% of the maximum longitudinal extension of the cutting region. Particularly preferably, the maximum longitudinal extension of the transition region corresponds to at least 5% of the maximum longitudinal extension of the cutting region. Preferably, the cutting region is configured over the entire extension of the saw blade. Preferably, the saw blade is arranged completely in the cutting region. Preferably, the saw blade has a maximum longitudinal extension which corresponds to the maximum longitudinal extension of the cutting region. Particularly preferably, the maximum longitudinal extension of the cutting region corresponds to the sum of the maximum longitudinal extension of the transition region and the maximum longitudinal extension of the functional region.

[0008] It is further proposed that the maximum longitudinal extension of the transition region is less than 38.5 mm. With this configuration, a favorably high bending stiffness of the saw tool can be provided in a small region. With this configuration, the overall weight of the saw tool can be favorably kept small.

The maximum longitudinal extension of the transition region in particular is at least 15 mm, preferably at least 10 mm and particularly preferably at least 4 mm.

[0009] It is further proposed that the base body has a thickness on an end of the base body facing away from the saw blade, in particular due to material cut-out, which corresponds to at most the maximum thickness of the base body in the at least one transition region, wherein the thickness on the end of the base body decreases towards the end of the base body facing away from the connecting region. With this configuration, the bending stiffness of the saw tool in the functional region towards the transition region can be favorably continuously increased. Thereby, the overall weight of the saw tool in the functional region can be favorably kept small. Preferably, the saw tool has a smaller bending stiffness on the end facing away from the connecting region than on the end of the transition region facing away from the connecting region. Preferably, the bending stiffness extends at least substantially linearly in the direction orthogonal to the cutting plane of the saw blade between the end facing away from the connecting region and the end of the transition region facing away from the connecting region. “At least substantially” in particular is to be understood as a deviation from a predefined value of at most 25%, preferably at most 10% and particularly preferably at most 5% thereof. Preferably, a free angle on the side of the base body tapers from the transition region up to the end of the base body facing away from the connecting region.

[0010] It is further proposed that the saw tool has at least one, in particular protrusion, which is produced in at least one functional region by material removal on the base body, which at least substantially extends parallel to the cutting edge of the saw blade. With this configuration, a favorably high bending stiffness of the saw tool in the functional region can be achieved. Thereby, the bending stiffness can be increased point by point on the base body. Preferably, the at least one protrusion has a main extension axis. Preferably, the main extension axis of the at least one protrusion extends at least substantially parallel to the cutting edge of the saw blade. Preferably, the at least one protrusion is configured as a web. The at least one protrusion is in particular provided for increasing the bending stiffness in a direction orthogonal to the cutting plane of the saw blade. Preferably, the at least one protrusion is arranged inside the recess.

[0011] It is further proposed that the at least one transition region has a maximum thickness on the end of the at least one transition region facing away from the saw blade, in particular due to material removal, which is smaller than the maximum thickness of the at least one transition region on the end of the at least one transition region facing towards the saw blade. With this configuration, the overall weight of the saw tool can be advantageously kept small. An advantageously material-saving profile on the base body can be provided, thereby achieving the durability of the saw tool. With this configuration, the saw tool can advantageously be simply and collision-free slid on the at least one guide roller of the hand-held power tool, in particular of the spike saw. Preferably, the base body has at least one shoulder and / or at least one chamfer on the end of the at least one transition region facing away from the saw blade. The at least one shoulder and / or the at least one chamfer is in particular provided for guiding the saw tool on the at least one guide roller of the hand-held power tool, in particular of the spike saw. It is particularly preferred that the maximum thickness of the base body on the end of the at least one transition region facing away from the saw blade is preferably at most 1.5 mm and particularly preferably at most 1.7 mm.

[0012] It is further proposed that the base body is made of an alloy having at least a quenched and tempered steel and nickel. With this configuration, a favorably high bending stiffness of the saw tool can be achieved. With this configuration, a favorably high breaking strength of the base body can be achieved. Preferably, the base body is heat treated. Thereby, the material properties of the base body in terms of high bending stiffness can be advantageously influenced. Preferably, the base body is produced from a sheet. Preferably, the sheet is configured as a strip.

[0013] Furthermore, a method for producing a saw tool is proposed. By means of the configuration according to the application, it is advantageously possible to produce a saw tool having a small overall weight, in particular a lightweight saw tool compared to a saw tool without a reduction groove. Thereby, it is possible to provide a saw tool having an advantageously small overall weight with simultaneously advantageously high bending stiffness. Particularly preferably, in at least one method step, the blank of the base body is formed by stamping from a sheet. Substantially, the blank can then or simultaneously be reshaped in a reshaping process. Preferably, in at least one method step, the introduction of at least one reduction groove, in particular of all reduction grooves, takes place 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 additionally, in at least one method step, the base body is machined in the functional region by means of a pressing process. Furthermore, alternatively or additionally, the base body in the functional region is machined in at least one method step as a result of a material-coating machining process, in particular additively by means of a 3D printing method, in particular for increasing the bending stiffness.

In particular, in order to meet the principles of action explained here, the saw tool according to the application and / or the method according to the application can have a number which deviates from the numbers of the individual elements, components and units and method steps mentioned here. Furthermore, within the value ranges specified in the present disclosure, values which lie within the mentioned limits should also be considered as being disclosed and as being arbitrarily usable.

[0043] The saw tool 10a has a base body 16a which is connected to the connecting piece 12a. The base body 16a is configured in one piece. The base body 16a is composed of an alloy (at least with quenched and tempered steel and nickel). The base body 16a is heat treated. The base body 16a is manufactured from sheet material. The sheet material is configured as strip material. In the present case, the base body 16a has a maximum thickness of 1.5 mm. Basically, the base body 16a has a maximum thickness of at most 2 mm.

In the present case, the base body 16a and the connecting piece 12a are configured in one piece.

[0044] The saw tool 10a has overlapping saw teeth 18a arranged on a base 16a. The saw teeth 18a differ from the construction of a wave-shaped grinding disc. The saw teeth 18a are constructed as overlapping saw teeth 18a. However, it is also conceivable that the saw teeth 18a have different configurations, which would be meaningful to those skilled in the art, especially different from the construction of a wave-shaped grinding disc, such as a configuration as milling and grinding saw teeth, a configuration as cross-grinding saw teeth, a configuration as riff saw teeth, a configuration as tool saw teeth, a graduated wave-shaped wedge grinding disc, or a configuration like the like. The saw teeth 18a can be directly incorporated into the base 16a, especially by milling, grinding, or similar constructions, or the saw teeth 18a can be constructed as saw teeth strips arranged on the base 16a by means of material-locking connections, such as welded connections or brazed connections, or the like. Furthermore, it is conceivable that the saw teeth 18a have a grain-loaded configuration, such as diamond grain-loaded or diamond grain-loaded, or the like.

The transition region 22a is arranged between the connecting region 14a and the functional region 20a. Relative to the functional region 20a, the transition region 22a has an increased bending stiffness in a direction orthogonal to the cutting plane of the saw teeth 18a. The cutting plane is configured as the main extension plane of the base body 16a in the functional region 20a. The transition region 22a is arranged between the connecting region 14a and the functional region 20a. The transition region 22a directly adjoins the connecting region 14a. The maximum thickness of the base body 16a in the transition region 22a is at most equivalent to the maximum thickness of the connecting piece 12a. The thickness extends orthogonally to the cutting plane. The maximum thickness of the connecting piece 12a is at least as great as the maximum thickness of the base body 16a in the transition region 22a. The maximum thickness of the base body 16a is in the transition region 22a the same as the maximum thickness of the connecting piece 12a. The transition region 22a and the connecting region 14a are arranged without overlap with one another. The transition region 22a directly adjoins onto the functional region 20a. The transition region 22a and the functional region 20a are arranged without overlap with one another. The connecting region 14a and the functional region 20a are arranged without overlap with one another. In the transition region 22a, an attachment point 24a of the saw tool 10a is arranged. In the present case, the base body 16a is materially bonded to the connecting piece 12a at the attachment point 24a. The transition region 22a is configured differently than a machine interface, in particular a shank.

[0047] The maximum longitudinal extension 26a of the transition region 22a has a ratio of less than 1 to the maximum longitudinal extension 28a of the functional region 20a. In the current case, this ratio is less than 0.1. In the current case, this ratio is 4 mm / 73 mm. In the current case, the maximum longitudinal extension 26a of the transition region 22a is less than 38.5 mm.

To achieve different rigidities, it is conceivable to adjust the length of the attachment at the attachment point 24d between the connector 12d and the base 16d, wherein the length of the attachment is measured parallel to the longitudinal axis of the saw tool 10d. This advantageously provides a saw tool 10d that varies depending on the application. Alternatively or additionally, it is conceivable to adjust the inclination angle of the bend 80d, the material thickness in the transition region 22d, and / or the shaping of the connector 12d and / or the base 16d at the attachment point 24d, in order to achieve different rigidities. Essentially, different rigidities can be additionally or alternatively achieved by means of a gap in the edge region of the attachment point 24d.
