A double face contact BT tool shank with high damping is developed to improve machining process in milling operation. The developed tool interface has rubber between flange and spindle nose. Its dynamic and machining characteristics are compared with those of conventional BT tool shank and commercially- available double face contact tool shank. Impulse response is examined during rotating. Stiffness of developed tool shank is higher than other shanks and it increases with rotation rate. As for machining characteristics, tool shank has little influence on its tool wear process. The develop tool shank removes high frequency component in machined surface profile because of high damping ratio of rubber at interface. Although the tests are performed in relatively low rotation rate, the developed BT tool shank shows better characteristics for machining operation than conventional BT tool shanks and ready-made double face contact one.
