Abstract: A machining device may include an electric motor, a blade rotatably driven by the electric motor for machining a workpiece, and a blade cover configured to surround the blade. A resonance sound reduction device may be disposed at the blade cover and may reduce air vibration generated by the rotation of the blade.

Abstract: A suspending member, such as a tether strap or the like, may by connected to improve convenience for an operator. The function of the suspending member shall be reliably performed by clearly notifying the user when the connecting part for connecting the suspending member is damaged. A ring-shaped notification member is incorporated in a connecting part for connecting the suspending member. The suspending member is inserted into both of a connecting hole in a connecting part and a notification member so as to be connected. When an end of a handle portion breaks due to long-term use, the notification member is pulled out such that the damage of the connecting part is notified.

Abstract: A dust collection nozzle extends from the front of a fixing cover parallel to a base below an upper end of an electric motor. Heavy and large cutting dust can be immediately collected from an area relatively close to a cutting position of a portable cutting device cutting a workpiece 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 is attached.
