PLUNGE SAW

A plunge circular saw， including a cutting body and a substrate pivotally connected to the cutting body. The cutting body contains a housing; at least one handle provided on the housing; a motor received within the housing; a circular saw blade mechanically connected to the motor; a battery pack electrically connected to the motor， and a hinge for pivotally connecting the cutting body to the substrate. The battery pack is detachably mounted to a trailing end of the cutting body. The cutting body is pivotable relative to the substrate by the hinge and movable between a cutting position and a parking position. The hinge is disposed at a position between the motor or the circular saw blade and the battery pack. The circular saw provided by the present invention improves the overall parallelism of the circular saw by changing the position of the hinge and gravity distribution thereof， thereby allowing the user to cut the workpiece more easily and accurately.
