Abstract: A power tool includes a motor and a controller in a power tool housing. A battery pack interface is defined on and/or in the power tool housing. A receptacle is defined on and/or in the power tool housing to removably accommodate a wireless communication adapter such that the wireless communication adapter is disposed entirely within a shell of the power tool and no portion of the wireless communication adapter extends beyond an outer contour of the power tool housing. At least one communication terminal is disposed within the receptacle and is electrically connectable to the wireless communication adapter. The controller outputs to the at least one communication terminal a signal indicating a charge level of a battery pack attached to the battery pack interface, a number of hours of operation of the power tool, a power tool overheated alert, and/or a battery pack overloaded alert.

Abstract: An operation switch sends an ON signal to a control processor indicating the operation switch is triggered by a user. A magnetic sensor sends a sensor signal to the control processor based on a displacement of a chip rod in a rearward direction. In the case where the sensor signal has not yet been sent, the control processor performs a control in a first mode where a brushless DC motor is not driven. In the case where sensor signal is sent, control processor performs a control in a second mode wherein the brushless DC motor is driven. An output in the first mode is lower than in the second mode. Because of this manner of construction, even if an ON input is triggered and held by the user, electric power is conserved while the operation switch is switched on and a hexagonal nut is not fastened, improving power consumption efficiency.
