Custom Impregnated Diamond Bit For Underground Rock Sampling

The Impregnated Diamond Core Bit is a professional rock coring tool designed for mineral exploration, geological investigation, geotechnical drilling and underground rock sampling.

The cutting crown is manufactured with synthetic diamond particles distributed throughout a specially formulated metal matrix. During drilling, the matrix gradually wears and exposes fresh diamond particles, helping the bit maintain cutting performance throughout its working life. This working principle makes impregnated core bits especially suitable for hard, competent and abrasive rock formations.

Brighttop Global Co., Ltd. can supply diamond core bits with different matrix hardnesses, crown heights, waterways and face profiles. The appropriate configuration should be selected according to rock hardness, abrasiveness, fracture conditions, drilling depth, rotational speed, water flow and drilling equipment.

Key Features

• Diamond-impregnated metal matrix crown
• Designed for efficient rock core recovery
• Fresh diamonds are exposed as the matrix wears
• Suitable for hard and abrasive rock formations
• Multiple matrix formulations available
• Different crown profiles and waterway designs
• Compatible with common wireline core drilling systems
• Custom sizes and specifications available

Matrix hardness and crown configuration should be matched to the actual ground conditions. Correct bit selection can help balance penetration rate, bit life and drilling stability.
