The reaming shell is an integral part of a diamond drilling system and acts as a coupling between the core bit and the outer barrel. It reams the hole to the proper size, and stabilizes the bottom of the drill string.

10-inch White Rhino reaming shells should be considered when bore hole deviation becomes an issue. With two rings, they provide a greater number of contact points than standard reaming shells. A 10-inch White Rhino is a good choice for underground drilling where adequate space can be a challenge.

• 2 diamond rings completely covered in diamonds to provide improved protection against bore hole deviation.
