In diamond core drilling jobs, a diamond drill bit is attached to the end of hollow drill rods to cut a cylindrical core of solid rock for examination on the surface, while a diamond reaming shell or called reamer shell is designed to sit above the diamond drill bit or high on the outer tube to ream the hole to the correct constant specific diameters, reducing the possibility of stuck tubes down the hole.

Reaming shell also acts as a stabilizer for diamond coring bits and core barrel during the whole drilling operation, preventing vibration and hole deviation. Helical type reaming shells provides good passages for water flowing, the matrix is wear proof and its service life is long.

Reaming shells consist of premium grade natural or synthetic diamonds set into spiral panels on the outside diameter of the shell, which are suitable to use in all conditions form broken and abrasive to consolidated and non-abrasive formations.

The outside diameter of the reaming shell is fractionally larger than the outside diameter of the core bit, there are Tungsten carbide (TC) reaming shell and diamond reaming shell, currently we only focus on diamond reaming shell, below are regular Q series reamer shells outer diameters.
