| 摘要 |
The present invention relates to a circular-saw blade, consisting of a master blade (1) with cutting elements (2) arranged distributed on the outer circumference and with a central orifice (3) for leading through a drive shaft. The master blade (1) consists of two mutually parallel discs (5, 6) which are spaced from one another by distancing means and between which are formed flow paths (8) for a cooling medium, having at least one inflow orifice and outflow orifices opening out on the outer circumference of the master blade (1) between the cutting elements (2). In the current invention, the distancing means are formed at least by elongate spoke elements (7) which are arranged essentially radially and distributed over the circumference of the master blade (1) and which between them form the flow paths (8). <IMAGE>
