Description

Core Advantages

Engineered for stable cutting and efficient core recovery

Three core design principles behind the PDC Double Cutter Core Drill Bit.

01 / 03

Double Cutter Design

The combination cutter structure improves cutting stability and helps maintain efficient drilling performance in medium-hard formations.

02 / 03

Stable Core Recovery

Optimized cutter arrangement reduces vibration during drilling and supports stable core sample recovery for reliable geological analysis.

03 / 03

Customized Solutions

Diameter, cutter quantity, cutter layout and thread connection can be customized according to specific drilling conditions.

Applications & Formations

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

	Geological Exploration Continuous rock cores for geological surveys and subsurface research.
	Rock Sampling Preserving rock core structure for accurate laboratory analysis.
	Mining Exploration Reliable samples from medium-hard formations for resource evaluation.
	Water Well Drilling Stable cutting performance for efficient borehole advance.
	Engineering Investigation Foundation surveys, bridge investigation, hydrological studies.

Suitable Rock Formations

Designed for medium-hard formations. PDC cutter configuration can be adjusted according to rock hardness and abrasiveness.

Limestone	Dolomite	Carbonaceous Limestone	Marl	Shale
Marble	Gneiss	Calcite	Other Medium-hard Rock

⚠️ Note: Actual drilling performance depends on rock abrasiveness, fractures, drilling parameters, cutter selection and operating conditions.
