Product Description

Product Description

Rehydration Port Impregnated Diamond Core Drill Bit

is a high-performance drilling tool designed for extracting precise core samples from hard materials like concrete, rock, and reinforced structures. It is ideal for water conservancy projects, structural repairs, and geological surveys, especially in rehydration port (water leakage repair) applications.

1. Premium Durability – Equipped with diamond segments or tungsten carbide tips for extended service life in tough conditions

2. Precision Cutting – Unique flute design ensures clean, smooth cores with minimal material loss

3. Efficient Cooling – Optimized water channels reduce heat buildup, enabling faster, safer drilling

4. Versatile Compatibility – Suitable for wet/dry drilling and works with most standard core drill rigs

Perfect for:  
* Water leakage repair in dams, tunnels, and foundations
* Structural inspection and sampling
* Geotechnical and mineral exploration
