Description
Four-Wing PDC Drag Bit for Non-Coring Drilling
Four-Wing PDC Drag Bit is designed for non-coring drilling applications that require stable guidance, balanced cutting and efficient penetration. The four-wing structure provides more cutting contact points and improved load distribution compared with conventional three-wing designs, helping maintain smoother drilling performance and better borehole stability.
Available from 75 mm to 325 mm with customized thread connections, PDC cutter layouts and reinforced configurations.

More contact points, smoother drilling
Six design advantages behind the Four-Wing PDC Drag Bit.
01 / 06 Four-Wing Balanced StructureThe four-wing design distributes cutting loads more evenly and improves drilling stability. | 02 / 06 Stable Borehole GuidanceAdditional wing support helps maintain smoother drilling and more consistent borehole direction. | 03 / 06 Efficient Rock CuttingThe PDC cutter arrangement provides efficient formation removal in suitable formations. |
04 / 06 Reduced VibrationMore cutting contact points help reduce vibration compared with lighter wing configurations. | 05 / 06 Wide Size RangeAvailable from 75 mm to 325 mm. | 06 / 06 Custom ConfigurationDiameter, thread connection, PDC cutter quantity and reinforced structure can be customized. |
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 drilling, coal mine drilling, gas drainage holes and engineering construction.
01 Water Well DrillingStable guidance and balanced cutting for efficient borehole advance. | 02 Anchor DrillingImproved load distribution 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 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. | ||||||||||
Which PDC drag bit should you choose?
The final selection depends on formation hardness, bit diameter, drilling rig and required penetration rate.
