Reaming Shells:

Reaming Shells are used together with Core Bits, maintaining the hole size and improving drilling stability.

The reaming shell is the component of a drill string used to maintain the correct gauge of the hole. It features a ring around the outer diameter which contains diamonds and/or tungsten carbide inserts which keeps the hole diameter consistent, otherwise there is a risk of the tools getting stuck down the hole.

A reaming shell is always placed just behind the bit, but can be used in other positions along the drill string. If a second reaming shell is placed at the other end of the outer tube, it can help to stabilize the core barrel (back end reamer).
