摘要： It is an object of the invention to provide a dust collecting circular saw in which cooling air to cool the motor can be further effectively utilized. According to the present invention, a representative dust collecting circular saw may comprise a blade, a motor, a cooling fan, a dust case, a dust case cover and an air space between the dust case cover and the dust case. The cooling air to cool the motor is designed to be introduced into the air space. Therefore, according to the invention, heat of the dust case caused by hot chips collected within the dust case can be prevented from being transferred from the dust case to the dust case cover by the air space into which the cooling air is introduced. Thus, the user of the circular saw can securely be escaped from contacting any circular saw members heated by the hot chips within the dust case.
