Diamond Core Drill Reaming Shell Sintering Processing NQ NQ2 NQ3 Type
 
 
Description:
The reaming shell is mainly used to connect core barrel assembly with diamond drill bit, and it is lined with natural or synthetic diamond. It can clean drill holes and keep these holes clean.
 
It can also be used as a stabilizer for drill bit. Excellent technology and high quality makes this reaming shell capable of protecting diameters of drill bits from damaging.
 
Spiral design is used for the reaming shell, and it has good water passing and powder discharging capacity. And it can be used in the drilling of various strata.
 
This reaming shell is mainly made up of steel body, polycrystalline diamond and carbide powder.

Application:
Our Reaming shells are suitable to use in all formation conditions ranging from broken and abrasive to consolidated and non-abrasive. As this kind of reaming shell is physically longer than the standard type, it is necessary to use an appropriate inner tube extension in order to compensate for the difference in overall reaming shell length.
