A Collet chuck holder, which can grip various rotary tools such as end mills, milling cutters, thin drills, and boring bars, is one of the most flexible tools. The holder plays a significant role as an interface between machining centers and cutting tools. However, gripping properties have not been clarified as yet. In this study, both gripping torque and gripping pressure are fundamentally investigated, in order to design a holder with high performance. In the experiments, several types of holders are tested. The single roll lock type has higher gripping torque as compared with other types, but its gripping torque is affected by the diameter and the coefficient of friction of the tool shank. In addition, with the use of a newly developed detector, the contact pressure distribution between the inner surface of the holder and the tool shank is measured. The pressure measured by means of the detector shows good agreement with the gripping torque.
