A tool system is used for a plurality of tools. Each of the plurality of tools is a portable tool and includes: a driving unit to be activated with power supplied from a power source; and an image capturing unit. The tool system includes a reference image generating unit and an output unit. The reference image generating unit generates, based on a second captured image, a reference image to be compared with a first captured image. The first captured image is shot, while a current work target is being identified, by the image capturing unit. The second captured image is also shot by the image capturing unit. The output unit makes a display unit display the second captured image while the reference image generating unit is generating the reference image.

The rotatable base rotates along a pivoting axis, and the rotatable base is removably connected with and driving a rotatable member. The impact member is removably connected to an outside of the rotatable base, and the impact member has at least one gravity unit projected outwardly therefrom. The gravity unit is driven by the rotatable base to rotate around the pivoting axis for generating a tangent impact force.

A power tool including a motor and an impact mechanism. The impact mechanism is coupled to the motor and includes a hammer driven by the motor, and an anvil positioned at a nose of the power tool, and configured to receive an impact from the hammer. The power tool also includes a sensor assembly positioned at the nose of the power tool, and an electronic processor. The sensor assembly includes an output position sensor configured to generate an output signal indicative of a position of the hammer or the anvil. The electronic processor is coupled to the output position sensor and to the motor, and is configured to operate the motor based on the output signal from the output position sensor.

An actuator assembly for a power tool includes an actuator with a permanent magnet. The actuator is moveable between a first position for a first mode of operation, and a second position for a second mode of operation. A first positioning member is adjacent the first position composed of a ferromagnetic material to attract the permanent magnet. A second positioning member is adjacent the second position and composed of a ferromagnetic material to attract the permanent magnet. An electromagnet may be energized to move the actuator between the first position and the second position. When the electromagnet is not energized and the actuator is in the first position, the actuator is retained in the first position. When the electromagnet is not energized and the actuator is in the second position, the actuator is retained in the second position. When the electromagnet is energized, the actuator moves between the first and second positions.
