| Abstract: | A high efficiency NBS impregnated bit was introduced in this paper. NBS material was added in the bit matrix, which has a sharp crystal and good bond strength with the matrix. The micro-drilling experiments and the field drilling tests show that this NBS diamond bit can greatly improve ROP in medium-weakly weathered hard rocks drilling and the bit service life is also prolonged compared with ordinary diamond bits. |

| Keywords: | NBS diamond bit high efficiency impregnated bit rate of penetration (ROP) hard formation |
