PQ HQ NQ PCD PDC rock coring drill bit for geological exploration
Depending on the range of application as well as the cutting media on the core bits, Forsun makes six types of core bits:
---Impregnated Diamond Type
---Surface set Diamond Type
---Tungsten Carbide Type
---PDC Type
---PCD Type
---Electroplated Diamond Type
Generally, an overall Drilling System consist of core bits, reaming shells, core barrels, drill rods and drilling rig.
Core Bits are used for drilling materials like the rock, concrete, limestone, granite, marble, clay, basalt, schist, quartz etc..
PDC bit has a long working life, very fast penatration and high percentage core recovery in soft to hard rock formations.
Because of the polycrystalline diamond cutters set on the crown, PDC bit has a long working life, very fast penatration and high percentage core recovery in soft to hard rock formations. PDC bit may be used with air, mud, or foam flushing.
PDC bits are an alternative to T.C. Bits and Surface set diamond bits, when drilling in non-consolidated and medium hard rock formation.
