Abstract
A core drill includes: a motor having a rotor, which is rotatable relative to a stator about a rotational axis extending in the front-rear direction; a speed-reducing mechanism, which is disposed more forward than the stator; an output shaft, at least a portion of which is disposed more forward than the speed-reducing mechanism and which, in the state in which a core bit is mounted thereon, is rotated by the rotational force of the rotor transmitted via the speed-reducing mechanism; a battery-mounting part, on which a battery pack is mounted; a motor-housing part, which houses the motor; a grip part, at least a portion of which is disposed along the extension of the rotational axis more rearward than the motor-housing part; and a controller, which controls the motor. In the front-rear direction, at least a portion of the controller is disposed between the motor and the grip part.
