Description
Three-Wing PDC Drag Bit for Non-Coring Drilling
Three-Wing PDC Drag Bits are manufactured for non-coring drilling projects where fast penetration and stable cutting performance are required. The three-wing cutting structure provides balanced drilling and efficient formation removal, making the bit suitable for a wide range of water well, anchor, grouting and geothermal drilling applications.
Different PDC cutter quantities and thread connections can be selected according to bit diameter, rock formation and drilling equipment.

Balanced cutting, efficient penetration
Six design advantages behind the Three-Wing PDC Drag Bit.
01 / 06 Three-Wing Drag StructureThe three-wing structure provides balanced cutting and stable guidance during drilling. | 02 / 06 Fast PenetrationThe drag-type cutting profile delivers efficient drilling performance in suitable formations. | 03 / 06 Efficient Cuttings RemovalThe open wing structure helps remove cuttings and supports smoother borehole advancement. |
04 / 06 PDC Cutter ConfigurationDifferent 1304 cutter quantities can be selected according to bit diameter and drilling conditions. | 05 / 06 Wide Size RangeAvailable from 75 mm to 325 mm for different drilling projects. | 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 three-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 formations. Reinforced cutter configurations can be selected for more demanding or moderately abrasive formations.
⚠️ Note: Actual drilling performance depends on rock hardness, abrasiveness, fractures, drilling parameters, cutter selection and operating conditions. | ||||||||||
1304 cutter layout with auxiliary support
The cutter layout can be adjusted according to diameter, rock formation and drilling requirements.
1304 Cutters Main Cutting ElementsUsed as the main cutting elements for efficient penetration and stable drilling performance. | Auxiliary Cutters Edge & Gauge ProtectionAdditional cutters can be added for edge protection, gauge stability and reinforced cutting. |
Reinforced Reinforced ConfigurationSuitable for larger diameters or formations requiring stronger cutter support. | |
