Several Key Technologies in the Design and Manufacture of Diamond Drill Bit with High Matrix

A variety of high-matrix diamond drill bits present in the market to meet the requirements of deep-hole drilling.In the field drilling,although the service life of high-matrix diamond bit has been further improved compared with the conventional ones,it did not achieve the desired effects.By analyzing the advantages and disadvantages of high-matrix diamond bits both in China and abroad,the key technologies affecting bit service life haven been found and further discussion and research were made on them.
