(54) Electrical power tool


(57) The present invention is to provide an electrical power tool which enables a user to grasp a rotation direction and a rotation speed of a tip tool. The electrical power tool (1) comprises a chuck (2) provided at 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 a tool body (3) so as to be able to operate, respectively bilaterally symmetrically protruded with a rotation axis of the chuck (2) therebetween, coaxially rotatable with the chuck (2), and urged so as to be self-restored to a neutral position. The chuck (2) is rotated in a direction according to a rotation direction of the switch (7) at a speed according to a rotation angle from the neutral position of the operation switch (7).
