8 1/2 XH S 8139 AB(24056) PDC Drill Bit with GI Cutter Grade and Steel Body for Hard Formations

The XH series is a high-durability drill bit line developed by Xingtong 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 an optimized structural design to deliver longer single-bit run times, reduce the number of make-up and break-out operations, and improve overall drilling efficiency in extremely hard formations.

• Suitable for hard formations to enhance drill bit life and penetration rate
• Optimized crown geometry ensures more uniform load distribution, reduces load on individual teeth in the tooth root, 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-flank tooth arrangement enhances drill durability while maintaining aggressive cutting performance

Drilling operations in extremely hard and highly abrasive formations that demand longer tool life and higher penetration rates.
