Abstract: A portable cutting machine includes an electric motor, a base having a lower surface coming in contact with a workpiece, a cutting machine body coupled to an upper surface of the base and accommodating the electric motor, a handle on a rear portion of the cutting machine body and at least partially rearward from a rear end of the base, a blade on a left or a right of the handle and rotatable with the electric motor, and a battery attachment portion receiving a battery pack for powering the electric motor. The battery attachment portion includes an opening directed away from the blade, an attachment surface standing with respect to the base, and a rail receiver extending in the attachment surface to receive the battery pack in a detachable manner. The battery pack on the rail receiver extends laterally over a center plane of the handle.

Abstract: A wind shielding portion is provided in a front side of an exhaust port for cooling air from a motor such that it crosses over a lateral width with respect to a cutting direction. The cooling air which is blown to the wind shielding portion is effectively blown through a ventilation portion having a small ventilating resistance force and towards a marking line guide. Even when the cutting device main body is set at an incline, the cooling air is blown to the wind shielding portion, and is effectively blown through the ventilation portion to the marking line guide.

Abstract: A dust collection nozzle 60 extends from the front of a fixing cover 14 parallel to a base 2 below an upper end of an electric motor 25. Heavy and large cutting dust can be immediately collected from an area relatively close to a cutting position C of a portable cutting device 1 cutting a workpiece W immediately after dust is generated due to the cutting, which can in turn improve dust collection efficiency of a dust collection device to which the dust collection nozzle 60 is attached.
