A variable tuned holder for machine tools that attaches to a machine tool to act in a manner similar to a dynamic absorber while the machine tool is used during machining. The natural frequency of the holder may be matched to the natural frequency of the machine tool as the tool is in use to reduce the amplitude of vibration at the cutting end of tool with a workpiece. The present invention is designed to provide an impedance match between the machine tool and the holder such that the cutting energy may escape and/or be dissipated. The flexible holder may be used as one part of an overall system. The system may be designed to be used with tools of different shapes and/or lengths. As the shape and/or length of the machine tool changes, the system may be easily modified to change the natural frequency of the flexible holder to enable the dynamic absorber effect of the flexible holder to occur. The flexible holder may be included in a kit that may be used with a wide range of lengths and/or shapes of machine tools.
