PROBLEM TO BE SOLVED: To provide technology for granting vibrating function to an angled drill in reasonable construction. SOLUTION: This angled drill comprises a driving motor stored in a body, a spindle 301 to be driven rotationally around a spindle rotating shaft 303 in the direction of intersecting an output shaft 213 of the driving motor, a body side cam member 403 arranged on the body side, and a spindle side cam member 401 provided on the spindle 301 in an integrally rotatable manner. The spindle side cam member 401 being rotated meshes and engages with the body side cam member 403 to permit the vibration of the spindle 301 in the direction of the rotating shaft. A body side cam member arrangement position switching means 503 is provided for switching the arrangement of the body side cam member 403 between an allowable position of meshing and engaging with the spindle side cam member 401 and a non-allowable position.
