Abstract
An electric power tool in one aspect of the present disclosure comprises a main body, a motor, a driver, a detector, and a kickback determiner. The kickback determiner determines that the main body is kicked back from a workpiece when an attitude change amount of the main body detected by the detector exceeds a preset kickback determination threshold during driving of the motor by the driver.
