PDC core drill bit

PDC bit can be divided to core bit, comprehensive drilling bit and sintering matrix bit. This kind bit has the advantages of long useful life, high efficiency, wide using range, good gage protection, high cost performance and so on. It can drill under low pressure and low-speed, mainly used in the fields of geological exploration, coalmine and conservancy projects & hydroelectric power for drilling. We can provide the matches PDC bit based on different geological conditions and the hardness of rock. Features 1. It has a super long life. The grinding/consumption ratio of PDC is 20-40 time higher than that of alloy bit and 10 times higher than that of diamond bit. 2. It has high drilling speed. 3. It can be operated with low pressure and low speed. 4. It has a good gauge protection. 5. It can be used widely, more suitable for drilling in the stratum with hardness coefficient<9. 6.It has a low cost. PDC Coring Bit PDC coring bit is a kind of pipe-shaped bit with PDC teeth,which can get the core.It is mainly used for geological exploration,coal mining,water conservancy and hydropower,constuction of road,railway,bridge and building. sizeouter/inner diameter(mm)sizeouter/inner diameter(mm)FQW65Φ65/44FQW100Φ100/75FQW75Φ75/54FQW110Φ110/85FQW78Φ78/57FQW113Φ113/88FQW91Φ91/68FQW130Φ130/105FQW94Φ94/71FQW133Φ133/108FQW98Φ98/73FQW171Φ171/146
