Product Description

8 1/2" Hybrid bit PDC-Roller compound bit for complex hard layer drilling


1.PDC-Roller compound bit

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.
