A portable electric tool including a reversible rotary electric motor and switch mechanism for reversing the direction of rotation of the motor. The switch mechanism includes a rotary holder member and an operating lever for the rotary holder member of the reversing switch mechanism. The lever extends obliquely outwardly relative to the rotary axis of the holder member and toward the rear side of the tool and slot means are provided on the lever coacting with projection means on the holder member for causing rotation of the holder member upon pivotal movement of the lever, to thus cause reversal of the direction of rotation of the motor.
