ABSTRACT:
A centering punch includes a first body, a second body, a punching head, an elastic body, an elastic member, a push member, and a spring. Thus, the tapered portion of the punching head is moved along the tapered face of the first body, and the punching head is moved radially in the receiving chamber of the first body by guidance of the tapered face of the first body, so that the push portion of the push member is in alignment with the control hole of the punching head easily and exactly.
