Product Description of Reaming Shells

Reaming Shells are used to maintain the critical hole diameter and to stabilize the drilling system in the hole during operation. The reaming shell is part of an overall drilling system that includes a core bit, a core capture mechanism (the core barrel assembly), the drill string (rods) and the drill rig itself.

Our reaming shells come in 6, 10 and 18 inches, which are ideal for drill rigs that are often used in underground drilling. Made with high-quality, synthetic diamonds, and a durable matrix. Friction-resistant, the well-designed matrix provides extra protection and maximizes lifespan.

It has the following advantages: 

1. Maximum active surface helps limit deviation

2. Surface-set synthetic diamond ring

3. Reinforced arrow tip pattern situated at the angle of contact with additional TSP diamonds provide greater protection.

6 inch Reaming Shells

The 6 inch reaming shell is the standard that is used for every kind of rock hardness or ground condition and is the minimum reamer requirement to provide minimum stabilization. Since the 6’’ has only one diamond pad, the vibrations from the rods and outer tube can be conducted easily and make deviation more likely.

10 inch Reaming Shells

You need to consider a longer reaming shell once deviation becomes an issue. A 10’ inch reamer is a good compromise between the 6 inch and the 18 inch. The 10 inch has two diamond pads so it will provide better stabilization. A 10 inch reamer is a good choice for underground drilling where adequate space can be a challenge. It will do the job in shallower holes requiring stabilization and where an 18 inch reamer may be just a bit too much. 10’’ is also mainly used with 3m core barrels, so you can still pull your 3m inner tube + extension in one shot.

18 inch Reaming Shells

You should switch to an extended reaming shell when you have to keep your hole on direction and avoid deviation. The more diamond pads that you have on the reaming shell, the more control you will have on deviation and on hole diameter. The 18 inch gives you 4 pads. The front diamond pads will help you stabilize the core barrel and control the direction while the pads in the back will help maintain the diameter of the hole.

You can use an 18 inch reaming shell on the front end and a diamond type locking coupling  on the back to make sure you have good stabilization of the core barrel. You can also use two 18 inch reamers when you have a longer core barrel (6 meters or more). It can act as a core barrel extension allowing you to get more core in the tube at one time.
