PDC Spiral Core Drill Bit for Geological Exploration

PDC Spiral Core Drill Bit is designed for geological exploration, rock sampling and water well drilling. The spiral body design helps improve fluid circulation and supports stable drilling performance, while high-quality PDC cutters provide good wear resistance in suitable medium-hard formations.

Available in 75–153 mm sizes with different PDC cutter grades and customized connections according to drilling conditions.

Engineered for stable cutting and reliable core recovery

Five design advantages behind the PDC Spiral Core Drill Bit.

Used across exploration, sampling and drilling projects

This PDC spiral core drill bit is suitable for geological exploration, rock core sampling and water well drilling. Other applications include mineral exploration and engineering investigation.

Applications Geological Exploration Continuous rock cores for geological surveys and subsurface research. Rock Sampling Preserving rock core structure for accurate laboratory analysis. Water Well Drilling Stable cutting performance for efficient borehole advance. Suitable Rock Formations Suitable for medium-hard formations. For more abrasive or structurally complex formations, reinforced PDC cutter configurations can be selected according to project conditions. Limestone Dolomite Carbonaceous Limestone Marl Shale Marble Gneiss Calcite Other Similar Medium-hard Formations ⚠️ Note: Actual drilling performance depends on rock abrasiveness, fractures, drilling parameters, cutter selection and operating conditions.
