Product Description

Geological Surface Set Diamond Reaming Shells BQ NQ HQ RQ PQ with Core Bit

 

Application                                                                                                                                                         

The surface set Reaming Shells are set natural diamonds outside of the shells, generally, with the stone size 20/30SPC. The rock cutters are flushed smoothly as the well design of the waterways.

Reaming Shell is set with natural or synthetic diamond,and it is used to couple the dril bit with the core barrel. Its main function is to ream the hole to the correct comstant specific diameter which ensures adequate clearance for the core barrel and sufficient clearance for the new bit which replaces an old one.It also acts as a stabilizer for drill bit.

Reaming Shells are used together with Core Bits, maintaining the hole size and improving drilling stability

 Characteristics

2. BQ,NQ,HQ,RQ,PQ,T2,T6,146,TT48etc

3. Favourable price and good quality
 

Five types of reaming shells for you to choose from:
Surface set Diamond Type
Impregnated Diamond Type
Tungsten Carbide Type
PCD Type
Electroplated Diamond Type

The key components in a reaming shell, diamonds and a well-matched matrix, have been selected and developed to yield a stable, long lasting product. Water channel and pad geometry have been optimised to match the requirements of today’s high penetration rates, allowing the bit to do its work without obstruction.
