Electroplated Diamond Core Drill Bit for Rock Sampling

Electroplated Diamond Core Drill Bit is designed for geological exploration, rock sampling and water well drilling. The exposed diamond cutting surface provides sharp cutting action, low drilling resistance and efficient penetration in suitable medium-hard formations.

Available from 75 mm to 245 mm, with different diamond grades, crown structures and core barrel sizes for different drilling conditions.

Sharp cutting surface, efficient penetration

Six design advantages behind the Electroplated Diamond Core Drill Bit.

Used across exploration, sampling and drilling projects

This electroplated diamond core drill bit is suitable for geological exploration, rock core sampling and water well drilling. Other applications include engineering geological investigation, mineral exploration, hydrological investigation and reinforced concrete coring in suitable configurations.

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 Electroplated diamond core bits are suitable for relatively intact medium-hard formations. Reinforced concrete coring is available with suitable crown and diamond configuration. Limestone Dolomite Shale Marble Schist Carbonate Rock Other Medium-hard Compact Formations ⚠️ Note: Actual drilling performance depends on rock abrasiveness, fractures, drilling parameters, diamond grade and operating conditions.

Diamond grades and crown structures

Different diamond grades and crown profiles can be selected according to formation abrasiveness and drilling requirements.

Standard sizes and specifications

Available from 75 mm to 245 mm. Diamond grade, crown design, connection and core barrel matching can be customized.

Which diamond core bit should you choose?

Electroplated and hot-pressed diamond core bits are designed for different drilling conditions. Bit selection should be based on rock hardness, abrasiveness, fracture condition, drilling depth and required core recovery.
