Description
Four-Wing Concave PDC Drag Bit for Non-Coring Drilling
Four-Wing Concave PDC Drag Bits are manufactured for non-coring drilling in water well, anchor, grouting, geothermal and construction applications. Compared with three-wing designs, the four-wing structure provides additional cutting contact and improved load distribution, helping maintain stable drilling performance and borehole direction.
The concave cutting face and optimized PDC cutter arrangement provide efficient rock breaking and reliable wear resistance in suitable formations.

Higher stability, improved load distribution
Six design advantages behind the Four-Wing Concave PDC Drag Bit.
01 / 06 Four-Wing Balanced StructureThe four-wing layout provides improved load distribution and stable guidance during drilling. | 02 / 06 Concave Cutting FaceThe concave profile supports efficient cutting and helps maintain stable borehole direction. | 03 / 06 High Cutting StabilityMore cutting contact points help reduce vibration and improve drilling consistency. |
04 / 06 PDC Cutter CombinationDifferent 1308 and 1304 cutter combinations can be selected according to bit size and formation conditions. | 05 / 06 Wide Size RangeAvailable from 75 mm to 325 mm for different drilling requirements. | 06 / 06 Custom Thread ConnectionsDifferent thread connections can be manufactured according to drill rods and drilling rigs. |
Used across water well, anchor and construction drilling
This four-wing PDC drag bit is suitable for water well drilling, anchor drilling, grouting holes and geothermal drilling. Other applications include slope support drilling, foundation support, coal mine drilling, gas drainage holes and engineering construction drilling.
01 Water Well DrillingFast penetration for efficient borehole advance in water well projects. | 02 Anchor DrillingStable guidance and balanced cutting for anchor and slope support drilling. |
03 Grouting HolesReliable hole formation for grouting and foundation support operations. | 04 Geothermal DrillingEfficient penetration for geothermal borehole and energy construction projects. |
Suitable Rock FormationsSuitable for soft to medium-hard and relatively intact formations. Reinforced cutter configurations are available for more demanding or moderately abrasive formations.
⚠️ Note: Actual drilling performance depends on rock hardness, abrasiveness, fractures, drilling parameters, cutter selection and operating conditions. | ||||||||||
1308 and 1304 cutter combinations
Different PDC cutter combinations are available according to diameter and drilling conditions.
1308 Cutters Main Cutting ElementsUsed as the main cutting elements to provide efficient penetration and wear resistance. | 1304 Cutters Auxiliary & Gauge CuttersUsed as auxiliary or gauge-support cutters to improve edge protection and drilling stability. |
Reinforced Reinforced ConfigurationAdditional cutters or reinforced layouts can be selected for larger diameters and more demanding formations. | |
Standard sizes and cutter configurations
Available from 75 mm to 325 mm. Cutter quantity, cutter layout and thread connection can be customized.
Which PDC drag bit should you choose?
Four-wing and three-wing PDC drag bits are designed for different drilling priorities. The final design should be selected according to bit diameter, rock formation, drilling rig and required penetration rate.
