Reaming shells are used for keeping the bore diameter and stability of drilling, reaming shells works together with core bits in the whole complete wireline core barrels. Electroplated diamond reaming shells in low price but with good performance, so suitable for soft to hard strata, but not for the strata of strong abrasion performance.

During the processing of electroplated diamond reaming shells, the matrix ring of electroplated diamond reaming shell is electroplated with layers of synthetic diamonds in the electroplated liquid. The electroplated diamond reaming shell can be applicable in soft to ultra-hard rock formations, but a short lifetime if drill very abrasive formations.

Reaming shells have various other minor features included for ergonomics, safety and precision. However, these tools are basically designed to withstand the boring conditions and facilitate aforementioned applications (drilling, enlargement, stabilization). The type of reaming shell chosen will depend on boring requirements, rock abrasives and hardness. The reaming shells should always be placed behind the core bit. However, they can also be placed on other positions across the strings of the drill. The core barrel can also be stabilized by placing a second shell across the other side of the outer tube.

Shell reamers come in various sizes and construction for different application areas. Our reamers are used for high intensity boring that require more force, precision drilling and heightened stability. As the name suggests, these tools are used for reaming holes and feature advanced technologies ranging from gauge monitoring and measurement to calculation of angular deviation. Reaming shells feature high intensity environment construction and are used for drilling through bearings with straight precision. They prevent angular deviation of holes especially for deep-hole drilling situations. Wireline core barrels have reaming shells as the most important parts and they are designed to maintain the drilling diameter. This way, the size and direction of the hole is kept consistent and precise respectively.
