PROBLEM TO BE SOLVED: To provide a circular saw blade with which cutting dust may be optimally discharged/removed and noise is reduced to minimum (less than 70 dB).SOLUTION: There is provided a saw disk comprising circular saw blade comprising: a saw blade main body 1 having a disk shape; a plurality of tooth of a saw 2 inserted into peripheral part of the saw blade main body 1 in a manner being arranged along with periphery of the disk; and notches 6 for discharging cutting dust which are arranged on peripheral part of the saw blade main body 1 and into which a base which has a height of the saw tooth 2 and onto which the saw tooth 2 are soldered is incorporated. At least one of the notch 6 in the saw tooth 2 defines the smaller volume for discharging cutting dust than apparent volume of cutting dust generated by the saw tooth 2.SELECTED DRAWING: Figure 5 |
