• Concentric String Tool

    Description

    Our concentric string tool is essential for helping you improve hole-opening efficiency. It centralizes the reamer even in irregular pilot holes, increases ROP, and allows you to use a range of pilot sizes. The tool is laterally stable and enables improved logging while drilling (LWD) response in the smaller pilot hole.
