Abstract: An electric tool may include a tool main body configured to be able to mount a battery pack. The tool main body may include an electric motor, a controller for controlling the electric motor, and a centrifugal fan rotatably driven by the electric motor for producing a flow of air. The controller may be positioned such that the flow of air produced by the centrifugal fan is applied to at least a part of the controller.

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 power tool may include a rotational force generating device and a rotational driven shaft coupled to a rotational drive shaft of the rotational force generating device via a transmission mechanism, so that the rotation of the rotational drive shaft is transmitted to the rotational driven shaft via the transmission mechanism. One or each of the rotational drive shaft and the rotational driven shaft is rotatably supported by at least three bearings.

Abstract: A hand-held cutting tool may include a handle and a battery pack. The handle has a rear portion with respect to a work proceeding direction along which the cutting tool is moved for performing a cutting operation. When the battery pack is mounted to the rear portion of the handle, the longitudinal direction of the battery pack extends non-parallel with the work proceeding direction.
