N/WL NQ Reaming Shell DCDMA Standard Highly Performance for Diamond Coring Exploration Drilling

Diamond Reaming Shell

H/WL HQ Reaming shell HD type O.D: 96.09mm

Reaming shells are designed to be placed behind the bit to ensure hole gauge and to help core barrel stabilization. Improving drill string stability and protecting lower drill string from excessive wear, and ensures that when a new core bit is inserted into a continuing bore hole there is a good chance of reaching the bottom of the bore hole without reaming.

Combined high quality and design make our reaming shells the best in the industry.

Three types of reaming shells can be selected: :Reinforce, Protector, Stability.

1. Reinforce(Only diamond)

2. Protector(Diamond and polycrystalline)

3. Stability(TSP thermally stable polycrystalline)

4. Size of Reaming shell
