PDC без отбора керна немного

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 gage 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 Non-coring Bit PDC non-coring bit is a kind of full face drilling bit,it is mainly used for coal mining,water conservancy and hydropower,construction of road and building. sizeouterdiameter(mm)sizeouter diameter(mm)FBN42Φ42FBN94Φ94FBN46Φ46FBN98Φ98FBN56Φ56FBN100Φ100FBN60Φ60FBN113Φ113FBN65Φ65FBN133Φ133FBN75Φ75FBN171Φ171
