Abstract

Abstract

The effects of diamond particle size and concentration on drilling performance and mechanical properties of Fe-Cu matrix bits were studied by using diamonds of the same concentration but different particle size, or the same particle size but different concentration in Fe-Cu matrix formula. Results show that the diamond bit with particle size of 40/45 and concentration of 50% has the best drilling performance by using granite at Fe-Cu formula, which is bit wear ratio of 9000 and drilling efficiency of 1.1 mm/s.
