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.
Fordia White Rhino and Black Rhino reaming shells are made with high-quality, synthetic and natural diamonds, embedded in a highly resistant matrix. The friction-resistant tungsten carbide inserts found on the leading edges of the ring provide additional protection and increased lifespan.
White Rhino reaming shells are also available in longer lengths for improved protection against drill hole deviation. Available in both 10 and 18 inches, these products have a greater number of contact points than standard reaming shells and are specially designed to achieve optimal straightness. They represent the perfect balance between performance and value.
6 inch White Rhino (15 cm) reaming shell features one diamond ring, which is standard and effective in the majority of competent bore holes. It is used for every kind of rock hardness or ground condition and is the minimum reamer requirement to provide minimum stabilization.
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 and an 18 inch reaming shell may be just a bit too much.
18-inch White Rhino reaming shells feature 4 rings provide additional core barrel stabilization that will help control and reduce deviation. They feature diamond rings that cut into the rock to widen and efficiently stabilize the drill string, as well as two additional rings to reduce friction and deviation.
Fordia’s Black Rhino reaming shells provide optimal performance in low torque requirements with less risk of premature wear. Made with high-quality, synthetic diamonds, and a durable matrix. Friction-resistant, the well-designed matrix provides extra protection and maximizes lifespan.
