て成る回転切削工具ホルダー。 A spindle with a tool chuck at the tip is concentrically supported in a holder body that is attached to a machine tool so that it can rotate around the axis and move in the axial direction within a certain range, and the holder body and the spindle, a first ball clutch for torque limiting, which has a function of urging the spindle in the extension direction and is capable of engaging and disengaging the clutch when the spindle is in the extension limit position; A second ball clutch for limiting thrust force that is held at the output limit position is interposed, and the second ball clutch is arranged so that when the first ball clutch is in the engaged state, the clutch ball is moved into the recess on the spindle circumferential surface. A rotary cutting tool configured to fit into the deepest part, and the depth of the recess gradually decreases in the circumferential direction so that the clutch ball rides on the spindle circumferential surface during relative rotation between the holder body and the spindle. holder.
