Polycrystalline Diamond Compact Drill

Brief introduction
The composite sheet was set shape is welded to a circular cylinder on the cutting tool, the cutting insert mounted on a drill bit body, a PDC bit. Than natural Diamond blade

drill bits PDC bits, low cost, but only for soft to medium hard formations. PDC bits in the early 1970s after the success of the manufacture and use, rapid

development, it is at a lower pressure and a high speed drill, drill footage height, unit footage low cost. China Oilfield use some polycrystalline diamond composite

sheet inserts welded on the blade, also received good results.
Classification
Geological exploration with PDC drill.
Mainly used in geological prospecting exploration PDC drill for soft to medium-hard rock, some manufacturers are now new research and development of new composite

sheet can be applied to ten hardness of rock.
Coal drilling using PDC drill.
Is mainly used in coal seam drilling on the excavation. Generally speaking relatively soft coal formations, PDC drill have been widely used, such as anchor bit, three

-wing drill and so on.
PDC drill bit with oil exploration
Mainly used in oil and gas drilling using the drill bit. At present, the oilfield PDC drill is all PDC drill inside the highest cost, requiring the highest. Can be

said that PDC drill inside the nobility.
