Reaming shell is used to couple the drill bit with the core barrel.
It is suitable for use on all conventional
and wireline core barrel. This product is mainly designed to ream
the hole to the standard diameter. It can
keep the stability of the core barrel. When the old bit is replaced

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
Surface set reaming shells are set natural diamonds outside of the
