6 1/2 XH S 6138 BK(24029) Size PDC Drill Bit with GI Cutter Grade and S432 IADC Code for Hard Formations

The XH series represents Xingtong's high-durability drill bit lineup engineered specifically for ultra-hard and highly abrasive formations. Designed with the core objectives of extending bit life and maintaining stable penetration rates, this series incorporates enhanced wear-resistant materials and optimized structural design to achieve longer single-bit run times in extremely hard formations.

This advanced design reduces the number of make-up and break-out operations while significantly improving overall drilling efficiency in challenging geological conditions.

• Suitable for hard formations to enhance drill bit life and penetration rate
• Optimized crown geometry ensures uniform load distribution, reduces load on individual teeth, and lowers the risk of core gouging
• High-performance imported PDC cutters enhance shoulder wear resistance and impact resistance, extending overall service life
• Unique rear-flute design enhances drill-bit durability while maintaining cutting aggressiveness
