HWL Wireline Core Barrel Surface Set Natural Diamond Reamer Reaming
Reaming shell is mainly made up of steel body, polycrystalline
diamond and carbide powder. It is manufactured with high-quality
synthetic and natural diamonds which are embedded in a highly
resistant matrix. 6" (one pad), 10"(two pads) and 18" (three pads
or four pads) and oversize reaming shells in industry standard
lengths are available.
This group of products is used to maintain the critical hole
diameter and to stabilize the drilling system in the hole during
operation. The reaming shell is part of an overall drilling system
that includes a core bit, a core capture mechanism (the core barrel
assembly), the drill string (rods) and the drill rig itself.
Situated just above the diamond core bit, reaming shell maintains
the outside diameter of the drill hole.
Diamond Reaming Shell connects the diamond core bit with core
barrel. Since its slightly more in outside diameter than the core
bit, reaming shell does job of reaming the hole.
Drilling crew should constantly check the outside diameter of the
reaming shell as less diameter of reaming shell or a worn out
reaming shell will result in stuck bit and drill string.
Wireline Reaming Shells are provide with TC inserts (Tungsten
Reaming Shells are set with fully processed natural diamonds.
Synthetic diamond (impregnated type) reaming shells are also
Reaming shells are manufactured in three matrix:
- Standard Matrix
- Medium hard matrix
- Hard Matrix
Diamond reaming shells as well as tungsten carbide reaming shells
for diamond core drilling, mineral exploration, geotechnical
investigation, soil testing etc.
1. Reaming shell is mainly used to connect core barrel assembly
with diamond drill bit. It is lined with natural or synthetic
diamond. It can clean drill holes and keep these holes clean.
2. It can also be used as a stabilizer for drill bit. Excellent
technology and high quality make this device capable of protecting
diameters of drill bits from damaging.
3. Spiral design is used for the reaming shell. This design has
good water passing and powder discharging capacity. And it can be
used for drilling in various strata.
1. Our products are manufactured with top quality diamond and metal
powders to ensure optimum performance and efficient reaming of the
2. Deep and wide waterway is designed to facilitate effective
flushing and contributes to a long service life.
3. It is placed behind the core bit to ensure the hole diameter and
to assist the core barrel stabilization.
4. Reaming shells are utilized to maintain the hole gauge and
stabilize the drilling system during the drilling operation in the
