Single Roller Bits

Top single cone bit cone using diamond composite tooth, enhance the wear resistance of teeth and improve the service life of the drill bit. Gage teeth bit body use large diameter cutting initiative gage ball gear, the drill bit has a good gage role and function backreaming.

Single cone bit is a kind of deceleration bit in which is the speed of cone is smaller than the speed of drill, mainly for disorderly cutting broken rock. It is suitable for old well sidetracking and deepening the slim hole drilling operation under high rotary speed and drilling pressure.

​​

  1. Its application field is wide, not only suitable for side drilling, it can also be used in deep well.

  2.  Working torque is lower than PDC bit at the same drilling pressure and formation condition. It can reduce the small size hole expansion, buckling problems to avoid down hole accidents.

  3. Single cone bit has advantages of both three cone bit and PDC bit, and make up the disadvantages of both. It is more suitable for large plastic formation than three cone bit, It can also be applied to hard inter layer which PDC bit cannot deal with.

  4. It can realize high speed and special drilling with down hole motor.
