Abstract
A cutting machine includes a housing accommodating a motor. In the housing, a cutting blade, an air duct, a dust collecting channel and a shutter member are provided. The cutting blade is operated with the driven motor to cut a workpiece, and the air duct allows cooling air generated by a cooling fan for the motor to be blown out onto a cutting place of the workpiece. The dust collecting channel has an opening at one end for serving as a dust collecting port located near the cutting place and an opening at the other end for permitting coupling of a dust collecting nozzle. The shutter member is movable between a closed position and an open position of the air duct and located in the open position in a normal state.
