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 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 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.

Abstract: A portable circular saw for cutting metal, a dust collection efficiency of cutting dust blown up from a cutting position into a cutting dust collection box is improved. A distance between in inner wall surface of a fixing cover and a tooth tip of a circular saw blade is set to longer than a distance between the tooth tip and a tooth bottom and also longer than twice as long as the distance. Furthermore, a distance between a front end of a window in a base and the tooth tip of the circular saw blade is set longer than the distance between the tooth tip and a tooth bottom and shorter than twice the distance.
