<P>PROBLEM TO BE SOLVED: To provide an electrical power tool in which a user can intuitively grasp a rotational direction and a rotational speed of a tip tool. Ž<P>SOLUTION: The electrical power tool 1 includes: a chuck 2 provided to a tip of a tool body 3, and rotatable with a tip tool held; and an operation switch 7 having operation protrusions 6 exposed to both side surfaces of the tool body 3 so as to be able to operate, and protruded respectively and symmetrically with a rotation axis of the chuck 2 therebetween, coaxially turnable with the chuck 2, and energized so as to self-return to a neutral position. The chuck 2 is rotated in a direction according to a turning direction of the operation switch 7 at a speed according to a turning angle from the neutral position of the operation switch 7.
