A three cone drill bit is a drilling tool suitable for various rock conditions, especially in soft, medium, and hard rock layers, which can demonstrate its advantages. Therefore, three cone drill bits are suitable for drilling a wide range of rock hardness, including medium and harder rocks.
However, it should be noted that although tricone drill bits can be used in various rock formations, different formation conditions and rock hardness may require different designs and configurations of tricone drill bits. Meanwhile, for certain specific formations, it may be necessary to combine other types of drill bits, such as PDC drill bits, to achieve better drilling results.
| IADC | WOB/(Bit Dia)(KN/MM) | RPM/(r/min) | Applicable Formations |
| 116 117 | 0.35~0.8 | 150~80 | Very soft formations with low compressive strength and high drillability,such as clay,mudston,chalk etc. |
| 136 137 | 0.35~1.0 | 120~60 | Soft to mesium soft formations with low compressive strength and high drillability.such as medium soft shale,hard gypsum,medium soft limestone.medium soft sandstone soft formation with harder nterbeds,ect. |
| 216 217 | 0.4~1.0 | 100~60 | Medium hard formations with high compressive strength,such as medium soft shale,hard gypsum,medium soft limestone,medium soft sandstone,soft formation with harder interbeds ect. |

Company Profile
Crossing Bit, a leading manufacturer of PDC bits and tricone bits in northern China, has exported its high-quality drill bits to more than 30 countries, demonstrating its strong market influence and exceptional product strength.
Crossing Drilling Tools has not only established a sterling reputation in the drilling, construction, HDD (horizontal directional drilling), exploration, water well, geothermal, mining, and oil & gas industries, but has also gained widespread recognition from customers for its exceptional product reliability and quality. We are committed to developing and producing a range of high-quality tools, including tricone bits, PDC bits, tricone cutters (single rollers), PDC reamers, drag bits, and HDD hole openers, to meet the diverse needs of our customers.
Our meticulously designed PDC bits are specifically optimized for directional drilling. With exceptional stability, durability, and "directional" friendliness, they are able to precisely maintain the bit's position in narrow and complex pay zones, ensuring smooth drilling operations.
This unique steerable bit technology, combined with high ROP (rate of penetration), sets Crossing Bit apart from the competition and establishes it as a leader in the industry.
