How to choose suitable tricone rock bit

The suitable bits with higher cost performance is the most important.Such as, high class bits are not cost-effective for general water well drilling. Because the water well drilling rig can’t drive the supreme quality bits to perform their best.But for deep water drilling, first class rock bits are cost-effective though it’s worth more.When inquiring, Please tell us more details about your drilling project so that we can recommend best suitable bits for your reference.
Tricone Bit Instruction

Transporation:As the small volume of tricone bit and heavy weight,safety should be noticed during transportation.The package is carton or wooden case.Waterproof and damp proof should be noticed during transportation.Validity:The roller bit should be utilized within four years after resembling.Type Selection:Appropriate bit should be choosen according to drilling formation lithology and reference on the conjoint well.
