Xingtong Drill Bit 8 1/2 XH S 8139 AB(24056)

The XH series is a high-durability drill bit line developed by Xingtong specifically for ultra-hard and highly abrasive formations, with the core objectives of extending bit life and maintaining stable penetration rates. In extremely hard formations, the XH 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.

1. Suitable for hard formations to enhance drill bit life and penetration rate.  

2. The optimized crown geometry ensures more uniform load distribution, reduces the load on individual teeth in the tooth root, and lowers the risk of core gouging.  

3. Select high-performance imported PDC cutters to enhance shoulder wear resistance and impact resistance, thereby extending the overall service life of the drill bit.  

4. A 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.
