Steel tooth tricone bits offer superior cutting efficiency, performing well in soft to medium formations.
| IADC code | Formation | Weight (kN/mm) | Rotary Speed (r/min) |
| 115 | Extremely soft formations with low compressive strength and high drillability, such as clay, mudstone, chalk, etc. | 0.25-0.70 | 200-80 |
| 127 | Soft formations with low compressive strength and high drillability, such as shale, clay, salt rock, soft limestone, etc. | 0.35-1.00 | 150-70 |
| 217 | Medium hardness with high compressive strength and hard interlayers, such as hard shale, sandstone, limestone, etc. | 0.5-1.20 | 100-50 |
| 337 | Highly abrasive hard formations, such as hard limestone, dolomite, hard sandstone, chert, etc. | 0.8-1.40 | 75-45 |
| Inch: Sanlong offers you standard sizes and custom sizes ranging from 3.5 to 26 inch. | |||
High efficiency: Steel tooth bits perform exceptionally well in soft to medium-hard rock formations, They offer efficient cutting and penetration in these formations, which can help improve drilling speed and productivity.
Low cost: Steel tooth bits typically have a lower initial cost compared to tungsten carbide insert (TCI) bits, making them a budget-friendly choice for many drilling operations.
