Kind Code:
Provided is a circular saw in which a maximum cutting depth of a cutting blade can be adjusted. The provided circular saw comprises: a base 4 which has an opening 4a allowing a cutting blade 6 to protrude therethrough, and to and from which it is possible to attach and detach a sub-base 7 that can slide on a material to be cut and that has a prescribed thickness; a motor 2 that rotationally drives the cutting blade; a housing 3 that covers the cutting blade while supporting and accommodating the motor, and that is pivotally supported about the axis of a pivotal shaft with respect to the base so as to be able to change the amount of protrusion of the cutting blade; and an adjustment mechanism 5 that adjusts the amount of protrusion of the cutting blade in order to adjust the cutting depth with respect to the material to be cut. The circular saw is characterized in that the adjustment mechanism is configured such that a maximum value of the cutting depth in a mounted state in which the sub-base is mounted on the base and a maximum value of the cutting depth in a non-mounted state in which the sub-base is not mounted are equal to each other.
