A power tool includes a brushless motor that has a stator including a tubular stator core, a rotor disposed in the tubular stator core, first and second electrically insulating members affixed to opposite ends of the stator core and a plurality of coils. A sensor-circuit board is supported by the first electrically insulating member. The first electrically insulating member is bounded by a first plane perpendicular to the rotational axis and a second plane perpendicular to the rotational axis, and the sensor-circuit board is located between the first plane and the second plane.
