Precision Diamond Reaming Shells LTK48 / TT48 With Core Barrel For Mining
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 rock formations.
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 conditions.
available in all standard drilling sizes . Also, non-standard sized bits can be produced according to requirements from clients.
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.
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 available.
