特徴とするドリルユニツト。 A sliding shaft is interposed between the main shaft of the drilling machine and the drill chuck that attaches the drill, and is composed of a spindle and a movable shaft, and is integrated with the movable shaft in a through hole formed in the center shaft of the spindle. is inserted so that it can freely move only in the axial direction without giving any movement in the rotational direction, and a spring is connected to the upper end of the sliding shaft to constantly pull the movable shaft upward, and the outer diameter is made relatively large. A disk-shaped ring is rotatably supported on a movable shaft via a bearing, a dolinch is attached to the lower end, and the spindle is fixed to the hole at the end of the main shaft. A drill unit characterized by transmitting rotational torque to a drill chuck while sliding it in the axial direction.
