High Air Pressure down the Hole Bits is a kind of popular rock drilling bits in the drilling market. There are mainly five types of DTH bits, that is, drop center bits, concave face bits, convex face bits, double gauge face bits and flat face bits. For carbide material, the arrangement of the tooth is mainly choose from button tooth, elastic tooth as well as button and elastic tooth. Brief introduction about some of these products will be given. (1)Convex Face Bits: this kind of bits includes two forms that is, single convex face and double convex face. The latter is mainly used for the DTH drill that has larger diameter. Convex face bits can maintain high drilling speed when it used for drilling hard and abrasive rocks. However, its glancing flatness is not so well, so it is not suitable to use it in the drilling engineer which has a high demand and requirements on the aspect of glancing flatness. (2) Flat Face Bits: this kind of bits seems to be much tougher, so it is more suitable to be used in some hard rocks. And it also suitable to be used in some medium hard and soft rocks if possible. (3)Concave Face Bits: bits in this kind of shape has a concave part in the top of the drill, which makes the drill has a excellent straightness during drilling, besides, it has good pulverized exhaustion and drilling speed, which deserves it become the most widely used DTH drilling bits in the present market. (4) Deep Concave Face Bits: it is evolved from the same kind of button drill bits. And the deep concave on the top of the drill is used for the nucleation effect in the process of drilling and guaranteeing its straightness when drilling. It is only suitable for medium hard and soft rocks. High Air Pressure down the Hole Tools includes four parts, that is, drilling machine, drilling robs, down-hole hammer and DTH bits. It gains its energy through compressing the air. Transfer the drilling power into the rock hole, control the action of the piston through down-hole hammer and then the energy will be transferred to the drill to drilling the rocks. DTH tools are widely used in these fields namely open-pit and underground mining, stone pit, water-power energy, water drilling, mineral prospecting and subway project. Characterized by good straightness, high finishing drill wall, good performance of impact system, unlimited drilling depth, low investment, convenient maintenance and so on, DTH tools are paid more attention to by the drilling engineer industries. Hole-blasting has been carried on in some small and medium sized mineral industries, which indicates that DTH tools have become increasing important. Compared with the traditional hand drill, it has many obvious advantages. For example, it seems to be more safety; it lowers the labor intensity; it improves the working situations; it improves the drilling speed and producing efficient, which benefit for increasing performance of enterprise. We provide our customers with excellent and high quality High Air Pressure down the Hole Tools. The whole process of producing is inconformity with producing standard featured by strict demand and requirements, advanced equipments and excellent and cooperative teamwork.
