Wireline double tube reamer

The SMC JS/XJS Series Reamer is a high-performance wireline double tube reaming shell designed to stabilize the drill bit and maintain the integrity of the borehole during core drilling operations. Positioned between the core bit and the outer tube of the core barrel, the reamer helps guide the drill string, ensuring straight drilling and reducing deviation—especially at greater depths.

Constructed with high-quality materials and embedded with wear-resistant elements, the JS/XJS Series provides extended life and consistent performance in abrasive or fractured formations. Its precision-machined design allows for smooth rotation and improved cutting efficiency, helping to maintain gauge diameter and minimize wear on the core barrel and bit.

Compatible with standard wireline systems, the SMC JS/XJS Series Reamer is available in multiple sizes to suit various drilling requirements and core barrel configurations. It is an essential component for maintaining hole stability, bit life, and core recovery quality in demanding exploration and geotechnical projects.
