Abstract
A method and apparatus mitigates vibration associated with the rotary cutting machines by providing a first dampening member which is disposed around a tool holder and positioned so as to be compressed intermediate the tool holder and spindle of the rotary cutting machine. A cutting tool is shrink fit to the tool holder. A neck is formed in an elongate shank of cutting tool and has dampening material disposed thereabout. The dampening material disposed around the tool holder, the dampening material disposed around the neck, and the shrink fitting of the cutting tool to the tool holder cooperate so as to minimize undesirable vibration of the cutting tool.
