Preparation and Drilling Performance of Orderly Arranged Diamond Bit

This paper introduces the application of orderly arranged diamond bit and the technology of realizing diamond orderly arrangement in bit. Two kinds of conventional bits and one bit with diamond orderly arrangement were used in the test to drill reinforced concrete. By experimental results: under the same conditions (same matrix, same diamond grade and concentration), the drilling speed of orderly arranged diamond bit is increased by 13.1%, the life is increased by 11.5%, compared with the conventional diamond bit. The drilling speed of orderly arranged diamond bit is increased by 15.8%, the life is increased by 8.9%, compared with the conventional bit which the matrix is same but the diamond concentration is 5% higher. On the basis of saving diamond and reducing cost of bit, orderly arrangement can still improve the efficiency and life of drill bit, it embodies the superiority of diamond bit with diamond orderly arrangement.
