1. A balance and runout amount adjustment system for a rotary tool comprising:
the rotary tool constituted by attaching a tool to a tool holder mounted on a spindle;
a balance determining device configured to obtain outer circumference position data of the rotary tool in the course of rotation of the rotary tool as being mounted on the spindle, respectively for a case of adding a predetermined mass to a predetermined position of the tool holder and a case of not adding the predetermined mass to the predetermined position of the tool holder and to determine a mass balance of the rotary tool from comparison between the outer circumference position data for the case of addition of the predetermined mass and the outer circumference position data for the case of no addition of the predetermined mass; and
a runout determining device configured to obtain shape data of the rotary tool in the course of rotation of the rotary tool as being mounted on the spindle and to determine a runout amount of the rotary tool based on the shape data obtained;
wherein the rotary tool, while being mounted on the spindle, is capable of adjustment of the mass balance based on the result of the determination made by the balance determining device and capable also, while being mounted on the spindle, of adjustment of the runout amount based on the result of the determination made by the runout determining device.
