<p>Circular saw blade having saw-teeth (1) arranged about its outer circumference (6) and a centre hole (4), wherein there are arranged distributed over the circular saw blade a number of grooves (5) which extend through the thickness of the saw blade. The grooves are arranged at a distance from both the outer circumference and the centre hole (4) and are provided over the greater part of their length with a width such that in the normal operating state of the circular saw blade and at a working temperature above room temperature the edges (12, 13) of the grooves come into contact with each other and form a mutually stabilizing, vibration-dampening support.</p> |
