Es sind Kreissägeblätter zum Sägen von Holz bekannt geworden, die am Umfang mindestens zwei in Schlitzen angeordnete Seitenschneiden aufweisen. Die radiale Erstreckung dieser Schlitze geht bis in die Zone, in der die Innenspannung durch Walzen 5 oder andere Verfahren eingebracht wird. Dadurch wird die Innenspannung mindestens zweimal völlig unterbrochen oder muß zu weit zur Bohrung hin verlegt werden. Da aber hohe Vorschubleistungen nur mit einer möglichst gleichmäßigen und im äußeren Durchmesserbereich durchgehend verlaufenden Innenspannung erreicht werden können, waren diese Sägeblätter für höchste Vorschubleistungen ungeeeignet. Außerdem hinterläßt jede Seitenschneide häufig eine störende Markierung auf der Schnittfläche.Circular saw blades for sawing wood have become known which have at least two side cutting edges arranged in slots around the circumference. The radial extension of these slots extends into the zone in which the internal tension is introduced by rolling 5 or other methods. As a result, the internal tension is completely interrupted at least twice or has to be moved too far towards the bore. However, since high feed rates can only be achieved with an internal tension that is as uniform as possible and continuous in the outer diameter area, these saw blades were unsuitable for the highest feed rates. In addition, each side cutting edge often leaves an annoying mark on the cutting surface.
Der Erfindung liegt die Aufgabe zugrunde, ein Sägeblatt zu schaffen, das diese Nachteile nicht aufweist. Dieses wird dadurch erreicht, daß das Kreissägeblatt an der Peripherie nur einen Schlitz zur Aufnahme der Seitenschneide aufweist und zur Auswuchtung auf der etwa dem Schlitz gegenüberliegenden Seite mindestens einen Durchbruch oder mindestens eine Abtragung an der Kontur oder mindestens eine Ausnehmung aufweist, die neben der oder den Innenspannungswalzlinien liegt. Bei diesem erfindungsgemäßen Sägeblatt ist die Innenspannung am Umfang nur einmal durch den Schlitz unterbrochen.The invention is based on the object of creating a saw blade that does not have these disadvantages. This is achieved in that the circular saw blade has only one slot on the periphery to accommodate the side cutting edge and, for balancing, has at least one opening or at least one removal on the contour or at least one recess on the side approximately opposite the slot, which is located next to the internal tension rolling line(s). In this saw blade according to the invention, the internal tension on the circumference is only interrupted once by the slot.
