Single cone little bit is a kind of deceleration bit, which is the pace of cone is scaled-down than the velocity of drill, mostly disorderly reducing broken rock. It is ideal for old effectively sidetracking and deepening the slender hole drilling procedure beneath higher rotary speed and drilling pressure. 

one. Its application area is wide, not only appropriate for aspect drilling, and can be employed in deep well. 

two. Work torque is decrease than PDC bit in the same drilling pressure and development problem. It can minimize the tiny dimensions gap expansion buckling issues, so that keep away from down hole accidents. 

3. Solitary cone little bit has positive aspects of equally a few cone bit and PDC little bit, and make up the negatives of both. It is a lot more suitable for big plastic formation than three cone little bit, also can be applied to tough interlayer which PDC little bit can not deal with other complex formation. 

4. It can understand higher velocity and specific drilling with down gap motor.


main barrel are utilised for drilling in cohesive and non-cohesive soil under groundwater stage. Digga’s drilling buckets are ideal for breaking and ripping tough soil up to medium difficult rock.
