High-Efficiency Roller Bit Cutting Ring
Equipped with high-performance roller bits , the cutting ring crushes rock instead of chipping it, ensuring faster penetration and higher efficiency in compact or hard formations.

Robust Structure for Hard Formations
Built with a thick shell, wear-resistant spiral strips, and stiffening rings, the barrel withstands heavy stress and abrasion, ideal for drilling in weathered or high-strength rock.

Modular & Easy Maintenance Design
Roller bits are easily replaceable (bolt or screw type), and the barrel supports full customization—diameter, length, and Kelly box size—to match different rigs and geological conditions.

Other lengths and diameters on request. All weigths are approximate values.
