Description
Three-Wing Concave PDC Drag Bit for Non-Coring Drilling
Three-Wing Concave PDC Drag Bits are manufactured for non-coring drilling projects where fast penetration, stable guidance and durable cutting performance are required. The three-wing balanced structure helps maintain drilling stability, while the concave face supports efficient cuttings evacuation and consistent borehole formation.
Different PDC cutter quantities and thread connections can be selected according to bit diameter, rock conditions and drilling equipment.

Balanced cutting, efficient penetration
Six design advantages behind the Three-Wing Concave PDC Drag Bit.
01 / 06 Three-Wing Balanced DesignThe three-wing structure provides stable guidance and balanced cutting during drilling. | 02 / 06 Concave Cutting FaceThe concave profile supports efficient rock cutting and helps maintain stable borehole direction. | 03 / 06 PDC Cutter CombinationMultiple PDC cutter combinations are available according to bit size and formation conditions. |
04 / 06 Fast PenetrationThe aggressive cutting structure provides efficient drilling performance in suitable formations. | 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 and relatively intact formations. For harder or more abrasive formations, reinforced cutter configurations can be selected according to drilling conditions.
⚠️ Note: Actual drilling performance depends on rock hardness, abrasiveness, fractures, drilling parameters, cutter selection and operating conditions. | ||||||||||
1308 and 1304 cutter combinations
Different cutter combinations can be selected according to bit diameter and drilling conditions.
1308 Cutters Primary Cutting ElementsUsed as primary cutting elements for efficient rock breaking and stable penetration. | 1304 Cutters Auxiliary & Gauge CuttersUsed as auxiliary or gauge-support cutters to improve cutting stability and edge protection. |
Reinforced Reinforced ConfigurationAdditional cutters can be added for larger diameters or 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.
