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: When the protruding length of a cutting blade 11 protruding below a lower surface of a base 2 of a portable machining device 1 is set to its maximum length, at least a part of a controller 31 for controlling an electric motor 12 is configured to be located behind a handle 14 in the front-to-rear direction. Furthermore, the controller 31 is disposed so as to be tilted in the left-to-right direction or in the up-to-down direction with respect to the cutting blade 11. Because of this configuration, the height of the handle 14 can be restricted and at the same time the controller 31 can be disposed in a compact manner.

Abstract: A communication adapter 31 for conducting radio communication between a portable machining device 1 and a dust collector 40, such that the dust collector 40 may operate synchronously with the portable machining device 1 with respect to a start/stop operation when performing a cutting task is detachably incorporated in a handle 20 of the portable machining device 1. Because of this arrangement, a high level of dust-proof ability as well as ease of maneuverability in attaching and detaching the communication adapter 31 can be achieved.
