The XHY series is a hybrid drill bit that seamlessly combines the durability of roller-cone bits with the high-efficiency rock-breaking capability of PDC bits. In hard-formation drilling, the XHY series strikes an optimal balance between directional control in high-strength formations and the need for rapid penetration, delivering outstanding performance in complex formations such as conglomerates and effectively addressing the limitations of pure PDC bits under specific operating conditions.

1. Suitable for directional drilling in hard formations and for increasing penetration rates in hard formations.

2. The drill bit adopts a mainstream design featuring dual-cone cutters and four cutting wings, with bearings and seals sourced from international suppliers, ensuring that its overall service life ranks among the industry’s best.

3. The optimized design of the cone-to-PDC cutter height differential enables composite drill bits to exhibit superior directional control and sidetracking performance in hard formations compared with PDC bits, thereby enhancing overall drilling efficiency.

4. The PDC-impregnated cutter teeth enhance the roller cone’s cutting performance, resulting in longer drill-bit durability when drilling through conglomerate and ultra-hard, highly abrasive sandstone.

Drilling operations in hard formations that require simultaneous consideration of durability and directional performance, such as directional drilling in hard rock formations and accelerated penetration in highly abrasive formations.
