Sealed bearing roller cutter

Kingdrilling roller cutter bit is according to characteristics of the formation mechanics performance, using calculation analysis method, optimizing the distribution of the insert, insert profile and it's quantity, calculating each row's highest cutting efficiency and movement direction precisely, to make the broken area and volume be the largest when each insert contact the hole wall.The most advanced metal surface sealing technology in the world is used on the sealed bearing. Compared with the runner seal, our seal bearing prolong the service life up to 35%.

Choice of the insert's shape size, brand are based on the actual working condition. It can adapt to carious types of rock which from 30MPa to 300MPa.

6. How to choose the suitable head face of the DTH drill bit?

a. Concave:

Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.

b. Convex: 

Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.

c. Flat:

Suitable for special hard formation stratum, especially for fracture, crack spacing and complex formation drilling effect is very good, has the good perpendicularity of the borehole.
