PROBLEM TO BE SOLVED: To provide an arbor for a rotary tool capable of restraining generation of bending and chatter vibration in the course of machining and improved in vibration control function by improving the conventional arbor. SOLUTION: This vibration control arbor is a steel-made arbor for holding a cutting edge at the axial end part, which has a spray layer on the outer peripheral surface of the arbor. The spray layer is formed on one of cemented carbide, ceramic and thermet having a thickness of 0.1 to 1.0 mm and Vickers hardness of 800 or higher.
