The invention provides a portable cutting machine. The required length of the base for supporting the cutting machine main body is determined according to the size of the saw blade and the like. In order to make the portable cutting machine compact, it is sought to make the cutting machine body compact instead of making the base compact. The cutting machine main body is compactly configured by theconfiguration and posture of the controller. When the cutting machine body is compactly arranged, the part suitable for arranging the display part becomes limited. A user observes the overlapping degree of the tool nose of the saw blade located in front of the electric motor and the ink line, and meanwhile the cutting machining condition is much. If the display part is separated from the blade tip of the saw blade, it is difficult to observe and work at the same time. Therefore, the portable cutting machine is short in front-back length and is provided with a display part which is easy to visually confirm when a cut piece is cut. In the present invention, a controller is positioned in front of a rotating shaft of an electric motor and above a base, and is disposed in a posture inclined forward from above.
