Abstract
A drilling tool includes a tool body, a brushless motor, a first detector, a second detector and a control device. The brushless motor is housed in the tool body and configured to drive the tool accessory. The first detector is configured to detect first information corresponding to a load applied to the tool accessory. The second detector is configured to detect second information corresponding to a rotation state of the tool body around the driving axis. The control device is configured to control operation of the drilling tool. The control device is configured to set a conduction angle for the brushless motor based on the first information, and to determine, based on the first information and the second information, whether or not excessive rotation of the tool body due to jamming of the tool accessory occurs.
