HQ Surface Set Core Drill Bit Reaming Shells DCDMA Standard Thread

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

Application

Reamer 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.
The matrix ring of PCD Reaming Shell is set with Polycrystalline Diamond. The Polycrystalline Diamond is produced from synthetic diamond sintered with bond under high temperature and high pressure; it has an impressive abrassion resistance and high thermal stability. The PCD reaming shell is suit for soft to hard rock formations.

Surface set reaming shells are set natural diamonds outside of the shells, generally, with the stone size 20/30. The rock cutters are flushed smoothly as the well design of the waterways.
Usually, we can make two types of Surface Set Reaming Shell, one is Spiral Rib Type, another is Spiral Segments Type.
Reaming Shells are used together with Core Bits, maintaining the hole size and improving drilling stability.

Characteristics

1. Available in all standard drilling sizes (A, B, N, H and P).

2. Combination of natural and synthetic diamonds embedded in sections

3. Ring completely covered with diamonds

Reliable material and advanced technology

Our reaming shells are made with high-quality, synthetic and natural diamonds, embedded in a highly resistant matrix. They have additional protection made from friction-resistant tungsten carbide to maximize lifespan, and their maximum active surface helps to limit deviation.

Optimized choices

Surface set reaming shells in all common DCDMA sizes are a stock item. Impregnated reaming shells and reaming shells in full hole profile are also available, but may require longer lead time.

Size Available as followings:

"Q" series: AQ, BQ, NQ, HQ, PQ

“TW” series: ATW BTW NTW HTW

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
