摘要

PURPOSE: An auto-centering type multi-chambering unit is provided to enable to correspond to a hole of a target object dislocated from a position of an initial design by bending an end portion of a drill tip within a range of a predetermined angle, thereby preventing burrs from being remained after processing and the generation of mechanical stress in a post process. CONSTITUTION: An auto-centering type multi-chambering unit(100) comprises a fixing unit(10), a bending unit(20), a joint unit(30), and a cutting tip(40). One end of the fixing unit is joined to a main shaft(310) detachably. One end portion of the bending unit is joined to the other end portion of the fixing unit and enables to be bent by an external force. One lateral surface of the joining unit is joined to the other end portion of the bending unit. The cutting tip is joined to the joining unit detachably.
