Advantages of reverse circulation bit: Based on previous experience of conventional hammer,combined with feature ofreverse circulation hammer,optimized internal structure and ideal energytransfer, to ensure the RC hammers achieves fast drilling rate stable and continuous sampling. The internal structure is very simple with components of high rigidity,thusensured hammer life and convenience of maintenance.The sample tube uses an integrative design and can be replaced withoutdisassembling the hanmmer. With carburizing treatment,it has good abrasiveresistance.Bits designed with patent . Simply by replacing the drill bit, the hanmmer candrill holes different from sizes and ensure that the sample is not contaminated.in tough conditions such as loose soil,hard rock and plenty of water exist,sampling can be done well. The application of reverse circulation drilling tools: Panda reverse circulation hammer is the newest developed product of our company. It is mainly used for deep exploration drilling and core sampling.
