1. Introduction:
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.
With ISO certificate & quality control.
