Diamond composite (PDC) bit high cost performance
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.

PDC Drill Bits Features:
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:
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).
According to customer requirements and geological conditions to
provide a variety of conventional diamond composite bit to overcome
the special formation of diamond composite bit.
