(2)good cutter
(3)long working life

Metal/Rubber Sealing Tricone Drill Bit
1.CuttingStructure

The durability of premium tungsten carbide inserts is improved with newformulas and new techniques for insertbit.

2.Gauge Structure
Multiple gauge protection with gaugetrimmers on heel and gauge inserts on the gauge surface of thecone, tungstencarbide inserts and hardfacing on the shirttail increases gauge holdingcapability and bearing life.  

3.BearingStructure

High precision bearing with two thrust faces. Ballslock the cone.Hardface heard bearing surface. Cone bearing inlaid withfriction-reducing alloy and then silver-plated. Abrasion resistance and seizureresistance of thebearing are improved and suitable for high rotaryspeed.

4.Seal and Lubrication

The advanced metalseal package consists of two metal seats and two elastic energizers. Compressedenergizers ensure good contact being kept on two sealing surfaces of metal ringsby elastic force, and achieve the bearing seal. In the drilling, metal seal arerelatively dynamic, and the energizers are static. This will improve thereliability and durability of bearing seal. The pressure compensator system andadvanced grease can greatly increase the lubricating reliability.

We take years to dealing with the both new and used drill bits, rock bits and PDC bit, if you want import or export the relevent goods, just contact us. We will show our warm welcome and satisfy your needs. Wish you all the best.
