Reaming Shells

EDGE Reaming Shells from Di-Corp are made to perform in the most demanding drilling environments. As they help maintain the hole gauge and stabilize the drill string, these reaming shells endure constant friction, pressure, and abrasive contact.

To ensure long-lasting performance, EDGE Reaming Shells are built with high-quality natural or synthetic diamonds for cutting efficiency, thermally stable polycrystalline (TSP) for added ring protection, and a wear-resistant matrix reinforced with carbide particles to reduce erosion. These advanced materials and construction techniques allow EDGE Reaming Shells to withstand high-stress drilling and deliver consistent performance, even in hard, fractured, or variable rock formations.

Reaming shells maintain and stabilize the borehole diameter during drilling. Positioned behind the drill bit, reaming shells use embedded abrasive elements, such as TSP, to smooth and stabilize the hole walls, reduce deviation, and prevent premature wear of the bit. Their design, including the type and placement of cutting elements and reinforcement materials, plays a key role in ensuring borehole quality and extending overall drilling tool life.

You should replace your reaming shells when the outside diameter (OD) wears below gauge or when the diamond layer becomes smooth and stops cutting effectively. Continuing to drill with a worn shell can lead to oversized holes, poor core recovery, increased vibration, and accelerated wear on your bit and core barrel components.
