High Precision Wireline Drilling Diamond Reaming Shells PCD Type
LTK48 /TT48 Diamond Reaming shell is set with natural or synthetic
diamond, and it is used to couple the drill bit with the core
barrel. Its main function is to ream the hole to the correct
constant 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 (with double pads or three pads) 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.
Specialisted in producing varies kinds of diamond core bits in
different international standard size for soft, medieum to hard
TT48/LTK48 Reaming shell
1.High penetration rate
2.High core recovery ratio
3. long life of drilling service
To select the right bit for the job, assess the speed and power of
your drill for the size and depths of the holes to be drilled and
assess ground conditions such as rock type/formation and down-hole
SINOCOREDRILL bits are available in all standard drilling sizes .
Also, non-standard sized bits can be produced according to
requirements from clients.
SINOCOREDRILL offers crown impreg depths of 9mm, 12mm, and 16mm
.The taller crown heights provide improved bit stability and
reduced vibrations, enhancing bit life and performance.
Various waterways are available for diamond impregnated bits.
Differing waterways allow for better flushing in various ground
conditions and drilling systems.
SINOCOREDRILL impregnated bits matrices can be selected by our
engineer according to ground conditions at client's work site.
standard Q threads as well as thread types required by clients are
