Turning tool and turning device
A turning tool includes a power receiving coil, a sensor, and a wireless unit. The power receiving coil receives power transmitted from a power transmitting coil in a non-contact manner. The sensor is electrically connected to the power receiving coil. The wireless unit transmits data detected by the sensor to an outside.
