Factory direct sale API 8 3/4" TCI tricone rock bit
A tricone bit is a mechanical drill bit located in the bottom hole assembly. The bit cuts away the surface of the rock being
drilled through rotation and mechanical friction caused by the teeth of the bit. Tricone bits are designed to take the energy of the rotating drill string and the supply of mud and to apply this force to deepen the well.
| IADC | Pressure(KN/mm) | Drill speed(r/min) | Applicable strata |
| 417/427 | 0.3-0.9 | 150-70 | Very soft strata have low compressive strength and high drillability, such as mudstone, gypsum, salt, soft shale, soft limestone, etc. |
| 437/447 | 0.35-0.9 | 150-70 | |
| 515/525 | 0.35-0.9 | 180-60 | Soft strata have low compressive strengthand high drillability, such as mudstone, gypsum, salt, soft shale, soft limestone, etc. |
| 517/527 | 0.35-1.0 | 140-50 | |
| 535/545 | 0.35-1.0 | 150-60 | Soft to medium-soft has low compressive strength, such as medium-soft shale, medium-soft limestone, medium-soft sandstone, forming medium-hard and hard grinding interlayer. |
| 537/547 | 0.4-1.0 | 120-40 | |
| 617/627 | 0.45-1.1 | 90-50 | High compressive medium-hard formation strength, such as hard shale, limestone, sandstone, dolomite, etc. |
| 637 | 0.5-1.2 | 80-40 | Hard strata have high compressive strength, such as sandstone, limestone, dolomite, gypsum, marble, etc. |
| 737 | 0.7-1.2 | 70-40 | Hard strata have high compressive strength, such as hard limestone, dolomite, etc. |
| 827/837 | 0.7-1.2 | 70-40 | Extremely hard strata with high compressive strength and abrasiveness, such as hard limestone, dolomite, hard sandstone, chert, etc. |
