Electroplated Diamond Core Bit for Medium-Hard Formations & Reinforced Concrete
High Core Integrity
Reinforced Concrete Preferred
Durable & Stable
The electroplated diamond core bit utilizes precision electroplating technology to uniformly and firmly attach diamond particles to the bit head. With sharp cutting edges and excellent wear resistance, it is specifically designed for medium-hard intact formations and reinforced concrete sampling. It performs exceptionally well in geological surveys, rock sampling, water well drilling, and reinforced concrete sampling in construction projects, offering high core integrity and stable drilling efficiency. It is the preferred solution for medium-hard formations and reinforced concrete coring.
Widely used in geological survey rock sampling, mineral resource exploration coring, water well drilling, and reinforced concrete sampling in construction projects (pile foundation inspection, structural inspection).
Core Advantages
Electroplating Process: Firm Diamond Bonding
Precision electroplating technology ensures tight bonding between diamond particles and the bit body, preventing detachment. Uniform particle exposure maintains long-lasting cutting sharpness, providing stable cutting performance in medium-hard formations and reinforced concrete while avoiding particle loss and edge breakage.
High Core Integrity & Sample Quality
Optimized bit tooth profile and layout design minimize rock/concrete core fragmentation and loss during coring. Conventional medium-hard formations achieve core recovery rate ≥95%, with excellent core integrity in reinforced concrete sampling, meeting sample quality requirements for geological analysis and engineering inspection.
Reinforced Concrete Preferred with Strong Cutting Performance
High hardness diamond particles provide efficient cutting capability for steel reinforcement and aggregates in reinforced concrete, effectively avoiding sticking and tooth breakage. It is the preferred bit for reinforced concrete sampling in construction projects (pile foundations, structures, etc.), offering higher efficiency and longer life compared to ordinary bits.
Wear-Resistant & Long Service Life
The electroplated diamond layer exhibits excellent wear resistance, with low wear rate in medium-hard intact formations and reinforced concrete. Each bit delivers longer footage, reducing bit change frequency and lowering construction costs and labor intensity.
Wide Adaptability & Multi-Scenario Application
Covers various mainstream size specifications, adapting to multiple scenarios including geological surveys, water well drilling, and construction sampling. Thread types are customizable, compatible with different drill rig models, and easy to operate.
Applications
Suitable Formations
Limestone, dolomite, shale, marble, gneiss, and other medium-hard intact formations.
Specifically adapted for: Reinforced concrete structures (pile foundations, beams, columns, etc.) sampling – preferred bit for this scenario.
Not recommended for loose fractured, highly abrasive, or ultra-hard formations (such as granite, basalt).
Drilling Method
Rotary Drilling – Recommended to use with water or low-solid mud circulation. Reinforced concrete sampling requires sufficient cooling and lubrication to improve cutting efficiency and bit life. During coring, control drilling pressure and rotation speed to avoid impact loads and ensure core integrity.
