Abstract
A core drill includes: a motor having a stator and a rotor, which is rotatable relative to the stator; a speed-reducing mechanism; an output shaft that, 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; and a battery-mounting part, on which a battery pack is mounted. A stator outer diameter, which is the outer diameter of a stator core of the stator, is 75 mm or more; and a stator length, which is the dimension of the stator core in an axial direction, is 30 mm or more.
