Description
Engineered for stable cutting and efficient core recovery
Three core design principles behind the PDC Double Cutter Core Drill Bit.
01 / 03 Double Cutter DesignThe combination cutter structure improves cutting stability and helps maintain efficient drilling performance in medium-hard formations. | 02 / 03 Stable Core RecoveryOptimized cutter arrangement reduces vibration during drilling and supports stable core sample recovery for reliable geological analysis. | 03 / 03 Customized SolutionsDiameter, cutter quantity, cutter layout and thread connection can be customized according to specific drilling conditions. |
Used across exploration, sampling and drilling projects
PDC Double Cutter Core Drill Bits are widely used in geological exploration, rock sampling, mining investigation, water well drilling and engineering projects.
Applications
Suitable Rock FormationsDesigned for medium-hard formations. PDC cutter configuration can be adjusted according to rock hardness and abrasiveness.
⚠️ Note: Actual drilling performance depends on rock abrasiveness, fractures, drilling parameters, cutter selection and operating conditions. | |||||||||||||||||||||
