14" tci tricone hole opener

The replacement hole opener is new type dilling products, we also custom manufacture reamers according to customers' special request.The Custom manufactured hole opener's OD are between 220m to 1600m.According to the feautes of drilling machine and different mdrilling formation.
We adopt more suitable toth type, bearing structure, sealing type and angle of ncdination of paws water cutting, good sand retuming can effectively reduce sand gathering, cones are made of hot-coating-anti-waring alloy reducing wearing.Unique anti- falling design of cones prevent the accident caused by falling cones which is leaded by bearing damage. If the cone damaged,could change it easily,enlarge the hdd rock reamer using life.

We have something to say to you.

1) Drill Bit Connection made according to API standard.

2) We can adjust the bit size according to your rig.

3) PDC bit is more expensive than roller cone bit, but its life is several times longer than cone bit, so it can save a lot of cost per meter. Now PDC bit is becoming popular in international drilling engineering.

4) The structure of PDC is simpler. We don't need to worry about the life of parts. We also provide wholesale PDC parts.

5) Drilformance PDC drill bits are engineered to engage a wide range of drilling formations and applications while delivering smooth, consistent torque. Drilformance PDC Drill Bits are the ideal choice for directional drilling, providing the ultimate in steerability thanks to a compact unibody profile coupled with proprietary PDC cutter technology.
