A portable circular saw including a housing that has a first housing side, a second housing side coupled to the second side, and a lower housing portion spanning the first housing side and the second housing side. The saw also includes a battery receptacle that is formed in the housing, and the battery receptacle extends partially into the first housing side and partially into the second housing side. The battery receptacle includes a bottom plate that is spaced apart from the lower housing portion to form an interior cavity within the housing. A drain feature extends between the bottom plate of the battery receptacle and the lower housing portion, and the drain feature defines an outlet for fluid in the battery receptacle.

A cutting tool 10 comprises a housing 30, and a handle 50 connected to the housing 30. The handle 50 comprises: a grip part 51; a first connection part 52 extending from one end of the grip part 51 toward a front side and fixed to a main body housing 32 of the housing 30; and a second connection part 53 extending from the other end of the grip part 51 toward the front side and fixed to the main body housing 32. Thus, a loop structure S is formed by the housing 30 and the handle 50. Then, a battery pack 100 to be attached to a battery attachment and detachment part 42 of a motor housing 40 is disposed in the loop structure S.

The present invention is a circular saw holder. In an embodiment, the circular saw bracket is provided with a ledge protruding from the body of the bracket. The ledge is further provided with a lip. The configuration allows the upper blade guard of a circular saw to rest on the ledge, while the lip engages the inside surface of the blade guard, preventing the saw from falling off the bracket. In an embodiment, through holes in the body allow the bracket to be mounted to a surface using screws.

An electric power tool is configured to drive a tool bit. The electric power tool includes a motor that includes a stator and a rotor. The stator includes a cylindrical stator core that includes an inner peripheral side with a slot, a first insulator and a second insulator installed on respective both end surfaces of the stator core, and a coil wound around the slot of the stator core via the first insulator and the second insulator. The rotor is rotatable with respect to the stator. The rotor includes a rotor core and a rotation shaft. The first insulator overlaps with the second insulator in the slot in an axial direction of the stator core.

An electric working machine of an example of the present disclosure includes: a motor; a power supply portion; a controller; and a voltage detector. The power supply portion generates a DC voltage to drive the motor by rectifying an AC voltage supplied from an AC power source and smoothing by a capacitor. The controller controls energization of the motor. The voltage detector detects the AC voltage. The controller is configured to interrupt the energization when the voltage detector does not detect the AC voltage.

An electric circular saw includes a saw blade, a drive assembly, a housing, and a base plate. The drive assembly is used for driving the saw blade to rotate around a first axis. The electric circular saw further includes a dust-blowing structure. The dust-blowing structure includes a wind-blowing assembly disposed on the drive assembly, a dust-blowing portion disposed on the base plate and a wind guide portion disposed between the dust-blowing portion and the wind-blowing assembly. The dust-blowing portion includes a flow guide hole and a flow guide groove disposed on the base plate. The flow guide hole is a through hole extending through the base plate. The flow guide groove is a groove disposed on the lower side of the base plate. The flow guide hole communicates with the flow guide groove.

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.

Provided is a DC power supply device If an electrical tool (81) of a rated voltage of 36 V is connected to the DC power supply device (1) (if the voltage of a lower positive terminal indicates the presence of a short bar), a microcomputer (30) performs control so as to switch a switching element (Q1) on and output a DC voltage of 36 V between an upper positive terminal and the upper negative terminal. If an electrical tool (81) of a rated voltage of 18 V is connected to the DC power supply device (1) (if the voltage of the lower positive terminal indicates the absence of a short bar), the microcomputer (30) performs control so as to switch a switching element (Q2) on and output a DC voltage of 18 V between the upper positive terminal and the upper negative terminal.

A circular includes a housing, a sawing assembly including a motor and a saw blade located at two opposite sides of the housing and connected together so that the saw blasé can be driven by the motor to saw the workpiece and a saw blade shield secured to the housing and covering a part of the saw blade to prevent the saw blade from cutting the surrounding people, and a prism assembly including a protective cover affixed to the front end of the saw blade shield and a prism located in the protective cover to reflect the image of the saw blade sawing the workpiece through a window of the protective cover to the line of sight of the operator. In this way, the operator can clearly confirm whether the sawing path is skewed with the normal operating posture to improve the efficiency.
