Beschreibung der Ausführungsbeispiele Figur 1 zeigt ein Oszillationseinsatzwerkzeug mit Verformungsausnehmungen 10a in einer Seitenansicht. Das Oszillationseinsatzwerkzeug, dem Fachmann auch als„Oscillating Machine Tool" (OMT) geläufig, weist ein Segmentsägeblatt 12a auf. Auch andere, dem Fachmann als sinnvoll erscheinende Sägeblätter, wie Stichsägen oder Säbelsägen sind hierbei denkbar. Das Segmentsägeblatt 12a umfasst einen ringsegmentförmigen Grundkörper 14a mit einem Schneidbereich 16a, sowie Schneidelementen 18a (Figur 2). Alternativ sind auch andere, dem Fachmann als sinnvoll erscheinende Formen des Grundkörpers 14a, wie zum Beispiel quaderförmige, denkbar. Die Schneidelemente 18a sind in Figur 1 ausDESCRIPTION OF THE EXEMPLARY EMBODIMENTS FIG. 1 shows a side view of an oscillating insert tool with deformation recesses 10a. The oscillating insert tool, which is also known to the person skilled in the art as an oscillating machine tool (OMT), has a segment saw blade 12a, and other saw blades which appear reasonable to the person skilled in the art, such as jigsaws or reciprocating saws, are also conceivable. The segment saw blade 12a comprises a ring segment-shaped main body 14a with a cutting region 16a, as well as cutting elements 18a (FIG. 2). Alternatively, other forms of the main body 14a that appear reasonable to the person skilled in the art, such as, for example, rectangular, are also conceivable. The cutting elements 18a are shown in FIG

Wie Figur 2 zeigt, erstreckt sich der Schneidbereich 16a ringsegmentförmig um eineFor clarity, not shown. The segment saw blade 12a can be used in particular in machine tools, such as multifunction tools. As FIG. 2 shows, the cutting region 16a extends around a segment in the manner of a ring segment

Innerhalb des Schneidbereichs 16a sind die Schneidelemente 18a formschlüssig mit dem Grundkörper 14a verbunden. Die Schneidelemente 18a sind aus einem härteren Material als der Grundkörper 14a geformt und an diesen angeschweißt. Es sind in diesem Zusammenhang auch weitere, dem Fachmann als sinnvoll erscheinende Befestigungsverfahren, die eine stoffschlüssige Verbindung herstellen, wie zum Beispiel löten oder beschichten, denkbar. Pivot axis 20a and in the radial direction 22a of a tooth base 24a to a tooth tip 26a. Within the cutting area 16a, the cutting elements 18a are positively connected to the base body 14a. The cutting elements 18a are formed of a harder material than the main body 14a and welded thereto. In this connection, further fastening methods which appear meaningful to a person skilled in the art and which produce a material connection, for example soldering or coating, are also conceivable.
Von dem Zahngrund 24a erstreckt sich die Verformungsausnehmung 10a über den Schneidbereich 16a hinaus in den Grundkörper 14a. Die Verformungsausnehmung 10a reicht dabei etwa siebenmal tiefer in den Grundkörper 14a hinein, als der Schneidbereich 16a. Eine Konduktion, die durch eine, bei einem Befestigungsverfahren auftretende Erhitzung eines an der Verformungsausnehmung 10a angrenzenden Schneidelements 18a entsteht, wird durch die Verformungsausnehmung 10a eingeschränkt. Ein Bereich 28a des Grundkörpers 14a auf einer gegenüberliegenden Seite der VerformungsausnehmungFrom the tooth base 24a, the deformation recess 10a extends beyond the cutting area 16a into the base body 14a. The deformation recess 10a extends approximately seven times deeper into the base body 14a than the cutting area 16a. A conduction which results from heating of a cutting element 18a adjacent to the deformation recess 10a during a fastening process is restricted by the deformation recess 10a. An area 28a of the main body 14a on an opposite side of the deformation recess
10a erhitzt sich daher weitgehend nicht mit auf. Therefore, 10a does not heat up to a great extent.
Die Verformungsausnehmung 10a ist tropfenförmig ausgebildet. Es sind jedoch auch alle anderen, dem Fachmann als sinnvoll erscheinende Formen, wie beispielsweise schlitz- förmig oder zackenförmig denkbar. The deformation recess 10a is drop-shaped. However, all other forms that appear appropriate to the person skilled in the art, such as, for example, slit-shaped or jagged, are also conceivable.
In der Figur 3 ist ein weiteres Ausführungsbeispiel der Erfindung gezeigt. Die nachfolgenden Beschreibungen beschränken sich im Wesentlichen auf die Unterschiede zwischen den Ausführungsbeispielen, wobei bezüglich gleichbleibender Bauteile, Merkmale und Funktionen auf die Beschreibung des ersten Ausführungsbeispiels der Figuren 1 bis 3 verwiesen werden kann. Zur Unterscheidung der Ausführungsbeispiele ist der Buchstabe a in den Bezugszeichen des Ausführungsbeispiels in den Figuren 1 bis 3 durch den Buchstaben b in den Bezugszeichen des Ausführungsbeispiels der Figur 4 ersetzt. Be- züglich gleich bezeichneter Bauteile, insbesondere in Bezug auf Bauteile mit gleichenFIG. 3 shows a further exemplary embodiment of the invention. The following descriptions are essentially limited to the differences between the embodiments, with respect to the same components, features and Functions can be made to the description of the first embodiment of Figures 1 to 3. To distinguish the embodiments, the letter a in the reference numerals of the embodiment in Figures 1 to 3 by the letter b in the reference numerals of the embodiment of Figure 4 is replaced. With regard to the same named components, in particular with regard to components with the same
Bezugszeichen, kann grundsätzlich auch auf die Zeichnungen und/oder die Beschreibung des ersten Ausführungsbeispiels in den Figuren 1 bis 3 verwiesen werden. Figur 3 zeigt eine zackenförmige Verformungsausnehmung 10b, die sich ausgehend von einem Schneidbereich 16b in einen Grundkörper 14b erstreckt. In principle, reference numbers may also be made to the drawings and / or the description of the first exemplary embodiment in FIGS. 1 to 3. FIG. 3 shows a tooth-shaped deformation recess 10b, which extends from a cutting region 16b into a base body 14b.
Figur 4 zeigt ein weiteres Ausführungsbeispiel der Erfindung mit einem Lochsägeblatt 30c aus dem Bereich der Lochsägeeinsatzwerkzeuge. Das Lochsägeblatt 30c weist einen hohlzylinderförmigen Grundkörper 14c auf. Der Grundkörper 14c weist einen Schneidbereich 16c auf, in dem das Material des Grundkörpers 14c härter ist als außerhalb des Schneidbereichs 16c. Die unterschiedliche Materialhärte ist auf ein Härtungsverfahren zurückzuführen, bei welchem der Schneidbereich 16c erhitzt wird. Figure 4 shows a further embodiment of the invention with a hole saw blade 30c from the field of Lochsägeeinsatzwerkzeuge. The hole saw blade 30c has a hollow cylindrical base body 14c. The main body 14c has a cutting region 16c in which the material of the main body 14c is harder than outside the cutting region 16c. The difference in material hardness is due to a curing process in which the cutting region 16c is heated.
Der Grundkörper weist ferner Verformungsausnehmungen 10c auf, die durch den Schneidbereich 16c in den Grundkörper 14c hineinreichen. Eine Konduktion durch die Verformungsausnehmungen 10c hindurch ist nicht möglich. Ein Verzug des Grundkörpers 14c bei einem Härtungsverfahren wird damit im Wesentlichen vermieden. The base body also has deformation recesses 10c, which extend through the cutting region 16c into the base body 14c. Conduction through the deformation recesses 10c is not possible. A distortion of the body 14c in a curing process is thus substantially avoided.
