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: A power tool including a brushless motor having a sensor circuit board has higher durability. The power tool includes a housing, a brushless motor including a rotor having a rotational shaft, a stator, and a sensor circuit board fixed to the stator and having a rotation detecting element that detects rotation of the rotor, and receiving the rotational shaft through the sensor circuit board, and a bearing held in the housing and supporting the rotational shaft. The bearing is located to overlap the rotation detecting element in an axial direction of the rotational shaft.
