By providing a cutout portion 24c on the lower surface of the front end portion of the chip storage box 24, the rotary saw blade 1 can be mounted even when the chip storage box 24 is attached.
The cut portion of the object to be cut 2 can be easily seen, and accurate cutting can be performed. Also,
As shown in FIG. 9, the chip storage box 24 is formed to be long in the front-rear direction and wider toward the rear.
A chip storage box 24 is provided at the side of the rotary saw blade 1.
The width of is narrowed. Therefore, the rotary saw blade 1
In the portion, the lateral protrusion can be reduced, and the chip storage box 24 is prevented from getting in the way during cutting so that comfortable work can be performed. Further, by reducing the lateral protrusion of the rotary saw blade 1 portion in this manner, the forward visibility is good and accurate cutting work can be performed. On the rear end surface of the chip storage box 24, a lid 26 rotatably attached by a rotation support portion 25 is provided so as to be openable and closable. Further, an air outlet 27 is provided in the upper corner opposite to the main body 5 at the rear end of the chip storage box 24 so as to extend over the side surface and the upper surface. In this way, when the air outlet 27 is provided in the upper corner opposite to the main body 5 at the rear end of the chip storage box 24 so as to extend over the side surface and the upper surface, the chip storage box 24 is introduced and stored. The chips are stored in order from the lower rear part in the chip storage box 24, but air can be discharged from a position away from the storage place of the chips, and the chip storage property in the chip storage box 24 can be improved. As a result, chips do not leak from the air outlet 27, and the exhaust air does not hit the operator with the fine chips, so that the operator can perform a comfortable work. The chip storage box 24 is transparent so that the amount of chips accumulated inside can be visually confirmed from the outside.
