Description
Five-Blade PDC Oilfield Drill Bit
Five-Blade PDC Oilfield Drill Bit features a robust steel-body construction and curved five-blade cutting profile for stable drilling and efficient formation cutting. The five-blade curved cutting structure distributes drilling loads across multiple blades, helping improve bit stability and cutter engagement during operation.
Multiple PDC cutter sizes, including 1613, 1308 and 1005, can be combined according to bit diameter and drilling requirements. Standard sizes range from 6 inch to 12-1/4 inch, with customized thread connections available.

Built for stable rotary drilling
Six design advantages behind the Five-Blade PDC Oilfield Drill Bit.
01 / 06 Five-Blade Cutting StructureFive blades provide multiple cutting contact points for balanced drilling and stable load distribution. | 02 / 06 Curved Blade ProfileThe curved blade geometry helps maintain smooth cutter engagement and efficient formation removal. | 03 / 06 Heavy-Duty Steel BodyRobust steel-body construction provides high structural strength for demanding rotary drilling applications. |
04 / 06 Multiple PDC Cutter Sizes1613, 1308 and 1005 PDC cutters can be combined according to drilling requirements. | 05 / 06 Large Diameter RangeAvailable from 152 mm to 311 mm, covering common oilfield sizes from 6 inch to 12-1/4 inch. | 06 / 06 Customized ConnectionsDifferent thread connections and bit structures can be manufactured according to drilling equipment. |
Designed for oilfield rotary drilling
This five-blade PDC drill bit is designed for oilfield rotary drilling, petroleum drilling, oil and gas well drilling, large-diameter rotary drilling and customized drilling projects. Final bit configuration should be selected according to formation characteristics, drilling parameters and rig requirements.
01 Oilfield Rotary DrillingStable cutting and load distribution for oilfield rotary drilling operations. | 02 Oil & Gas Well DrillingDesigned for petroleum and oil and gas well drilling projects. |
03 Large-Diameter Rotary DrillingSuitable for large-diameter rotary drilling projects up to 12-1/4 inch. | 04 Customized Drilling ProjectsCutter layout, connection and bit size can be adapted to specific project needs. |
Formation SelectionThe suitable formation range depends on the following factors. Different cutter configurations can be selected according to actual formation conditions.
⚠️ Note: Final bit configuration should be selected according to formation characteristics, drilling parameters and rig requirements. Please contact our engineers for formation-specific recommendations. |
Three PDC cutter sizes working together
A key feature of this bit is the combination of different PDC cutter sizes — 1613, 1308 and 1005 — working together across the five-blade structure.
1613 Cutters Primary Cutting ElementsUsed as major cutting elements on the primary blade structure. | 1308 Cutters Secondary Cutting & SupportUsed as secondary cutting and support elements according to blade layout. | 1005 Cutters Auxiliary & ProtectiveUsed in auxiliary cutting and protective positions depending on bit design. |
Customized Layout Customized Cutter LayoutCutter quantity, size, position and grade can be adjusted according to bit diameter and drilling conditions. | ||
