摘要： A holder for a rotary cutting tools has a holder body fixed to a spindle of a machine tool. A rotatable shaft concentric with the holder body and having a tool-mounting portion at one end thereof is coupled at its other end portion to the holder body to receive torque from the holder body. The rotatable shaft is so mounted as to be radially displaceable and inclinable relative to the holder body. A positioning member is fixedly disposed on the machine tool body radially outwardly of the spindle. A cylindrical casing disposed radially outwardly of and rotatably engaged with the rotatable shaft such that the casing and the shaft are rotatable relative to each other, the casing being engageable with the positioning member for accurate positioning thereof by the positioning member, and thereby positioning the rotatable shaft. The holder may further have a circumferential lock mechanism for locking the casing and the holder body to prevent relative rotation between the casing and the holder body when the holder is not attached to the spindle, and for allowing relative rotation after the holder has been attached to the spindle.
