PDC Carbide Rock Medium / Hard Rock Drilling Drill Bits
Brief Introduction
Diamond composite (PDC) bit, with diamond composite as the main cutting element, adopts the principle of scraping and shearing to carry out rock crushing, which is suitable for drilling in soft to medium hard stratum, and has better advantages in overcoming incomplete stratum drilling.By making full use of the high wear resistance and high impact resistance of diamond composite bit, it has the advantages of high life, high aging and high cost performance.

Features of pdc drill bits:
This kind of bit good stability and long service life, high drilling efficiency, low pressure drilling, at a moderate speed gauge effect is good, widely used and has the characteristics of superior cost-effective.
Applications of drill bits:
It can be widely used in geological exploration, coal mining, water conservancy and hydropower construction development (Wells), geothermal hole, highway, railway, the construction of the construction of the pile of rock drilling and pumping heart sampling check.
According to the use of the field: geological exploration with the composite bit (mainly used for geological exploration of the composite bit, suitable for soft to medium hard rock, now some manufacturers new research and development of the new composite piece can be applied to the tenth degree of hardness of the rock.The coal field drill adopts the composite bit (mainly used in the coal mine upper coal seam drilling and mining.Generally speaking, the rock formation in coal field is relatively soft, and composite bit is widely used, such as rock bolt bit, three-wing bit, etc.Composite bit for oil exploration (mainly used in oil and gas fields).
