API 8.5 inches hybrid drilling bit PDC-roller compound for complex hard
Product Description
Wholesale API hybrid drill bits combing fixed cutter and rollor-cone from China factory
Hybrid drill bit combines roller cones and PDC fixed cutters into a single, to reduce drilling time and trips in the most complex applications. With the rock-crushing strength and stability of roller cones and the cutting superiority and continuous shearing action of diamond bits, the hybrid drill bit increases ROP, improves cuttings removal, and survives highly interbedded formations with performance consistency and excellent toolface control.
Higher ROP potential than roller cone drill bits
Compared to roller cone bits, hybrid drill bits can increase ROP, requiring less weight on bit and minimizing bit bounce.
Optimized drilling dynamics compared with PDC
Compared with PDCs, hybrid bits are significantly more durable when drilling through interbedded formations. They reduce stick-slip and simplify drilling torque management while making it more consistent, enabling smoother transitions through varied formations. Improved stability and directional control enable better vertical control as well as higher build up rates in curve sections.

Product Specification
PDC-Roller compound bit is composited by PDC fixed cutting and roller free cutting structure.Rock will be broken by roller teeth's impact crushing,it'll forms breaking pits on bottom,the uneven surface will weaken rock strength. Under roller'helping,the PDC will bites into the layer. The function is obviously on cutting and save work.
Whereas,the complex and hard drilling stratum,we developed individually compound bit serial. The bit has a higher adaptability,has higher rock breaking efficiency and RPM in hard stratum/abrasive stratum/high intensity mud shale/uneven layer(instance,boulder bed) etc hard drilling layer.
Far Eastern have exported more than 30 countries services experience to supply the drill bits and advanced drilling soulutions for many different applications. The application including oil field,natural gas,geological exploration,driectional boring,mining ,water well drilling ,HDD, construction,and foundation.The various drill bits can be customized as per different rock formation becasue we have our own API & ISO certified factory of drill bits. We can give our engineer's solution when you can supply specific conditions, such as hardness of rocks,types of drilling rig,rotary speed,weight on bit and torque. It is also hlep us to find the siutable drill bits after you can tell us vertical well drilling or horizontal drilling ,oil well drilling or No-Dig drilling or foundation piling.
