The use of all kinds of drilling tools in the Chinese market, the drill bit is direct effects on the rock, is also one of the most vulnerable to damage parts of drilling operation. The most frequently used drill bit at present in China is a kind of flake drill bit, it appears the earliest in our country, also is the most widely application scope, production one of the largest varieties of drill bit. Flake drill bit mainly include a word bit, cross bit, and X qian first class, etc. Among these drill bit, drill bit a word on the domestic market share has reached more than 83%. A word drill bit is mainly used in drilling in the drilling for all sorts of small holes or shallow hole. The cross, X type bit, mainly is suitable for drilling medium hard rock or hard hole depth. A word bit, cross bit, and X type drill bit, because of the structure of their stress area is generally small, in the process of drilling operation work its efficiency is low, in the make a word when the drill bit, on the hardness of alloy is higher, the use amount of alloy is larger, thus prone to high production costs, and the resulting waste of raw materials. Because a word bit and cross drill bit and drill bit X are relatively small, and drill bit bearing is relatively concentrated, so in the process of the production and use, the diameter of the drill bit has also been a certain limit. At present in the Chinese market, in addition to some of the more low-end market demand and the special circumstances of hard ore is used in the process of drilling, the drill bit has gradually can not meet the needs of the Chinese market, although the improvement of science and technology, the drill bit will eventually quit the stage of history.
