The unit system attached to was the millimeter, which is the unit of length permitted by the Measurement Law, but instead of this, the scale 62 that adopted the unit system based on the shaku-niki method, such as the dimension and the minutes that have been used conventionally, is used. A circular saw blade 61 shown in addition to the linear scale 21 as shown in FIG.
You may use it as a circular saw blade with a single mark on the side.

定精度も向上する。As described above, according to the circular saw according to the present invention and the circular saw blade used for the circular saw, a graduation representing the length from the cutting edge of the circular saw blade toward the center is provided on the circular saw blade. Since it is displayed on the side, it is possible to measure the depth of cut just by reading the scale displayed on the circular saw blade, and there is no need to use a measuring tool such as a pen as in the conventional case. Therefore, the workability of adjusting the rotating position of the surface plate is improved, and the cutting depth setting accuracy is also improved.
【００４８】また、丸鋸には、通常、丸鋸刃を覆う可動

がなくなり、安全性が向上する。Most of the circular saws are usually provided with a movable cover for covering the circular saw blade.
Since the depth of cut can be measured while the cutting edge of the circular saw blade is covered with the movable cover, it is not necessary to shift the movable cover, and safety is improved.
