Economical drilling for soft formations
Six design advantages behind the Three-Wing Carbide Drag Bit.
01 / 06 YG6 Cemented Carbide CuttersHigh-quality carbide cutters provide good wear resistance and reliable cutting performance in soft and medium-soft formations. | 02 / 06 Three-Wing Drag StructureThe three-wing layout provides aggressive cutting and efficient formation removal during non-coring drilling. | 03 / 06 Fast Penetration in Soft FormationsThe open cutting structure is designed for efficient drilling in soil, shale, weathered rock and similar formations. |
04 / 06 Wide Size RangeStandard sizes are available from 113 mm to 240 mm, with customized diameters available up to approximately 325 mm. | 05 / 06 Multiple Thread ConnectionsREG, NC and other customized thread connections are available for different drilling rigs and drill rods. | 06 / 06 Economical Drilling SolutionCarbide drag bits provide a practical solution for projects where a PDC structure is not necessary. |
Used across water well, grouting and soft formation drilling
This three-wing carbide drag bit is widely used for water well drilling, grouting holes, gas drainage drilling and geothermal drilling. Other applications include anchor drilling, slope support drilling, foundation construction, engineering drilling and soft formation boreholes.
01 Water Well DrillingFast penetration in soil and soft formations for efficient borehole advance. | 02 Grouting HolesReliable hole formation for grouting and foundation construction projects. |
03 Gas Drainage DrillingEfficient drilling in coal seams and soft interbedded formations. | 04 Geothermal DrillingStable penetration for shallow geothermal well and energy projects. |
Suitable Rock FormationsDesigned primarily for soil and soft to medium-soft formations. This bit is not intended for hard or highly abrasive rock.
⚠️ Note: This carbide drag bit is designed for soft to medium-soft formations. For consolidated or medium-hard rock, please refer to our PDC drag bits. | ||||||||||
