| Abstract: | In the present paper, the fracture mechanism of bit buttons is analysed, and efficient measure- merits for reducing the fracture rate, especially the new techniques of button holding with either copper powder or copper sleeve, are suggested and tested. It is possible for these methods to reduce the fracture rate of bit buttons. |
