| Abstract:This paper analyzes needs for application of high quality drill bits, indicates the research direction of high quality drill bits. It designs a kind of layer drill teeth, pressed using preliminary cold press, then sintered under press in mold into pregnant diamond drill bit. It gives the parameters of selection of raw materials and manufacturing, analyzes results of drill test. The results shows that: this kind of drill bits are good for improving drill conditions and drill efficiency, to effectively save energy consumption in the manufacturing of drill bit. It is a kind of drill bits with bright future of broad application. |
