Abstract
A tool holder has a cutter arbor. The cutter arbor has a shank portion detachably mounted on a spindle, and a mechanism for holding a cutting tool. In the cutter arbor portion, a cavity portion is formed. In the cavity portion, a vibration damping material is filled at a filling rate so as to be capable of obtaining predetermined vibration damping characteristics. Thus, it is possible to provide high vibration damping characteristics, effectively damp vibrations during cutting and improve working precision, without using any special materials, such as damping materials, although the tool holder has a usual shape.
