Diamond Drill Bit for Hydroelectric Exploration


Diamond Drill Bit for Hydroelectric Exploration



This series of drill bits are mostly used in covering layer, cobble layer, foundation layer and ferroconcrete where drill bits often fail because of severe wear of the matrix and the steel body. Our drill bit for hydroelectric exploration is manufactured with special protection for the matrix and the steel body to ensure higher efficiency and longer tool life of the bit. These geotechnical diamond drill bits are usually electroplated or hot press sintered, and the hardness of the matrix is HRC20-40.

1. Our diamond drill bit for hydroelectric exploration last longer than competing products (ultra-abrasion resistant gauges)

2. Maximize penetration rates with this geotechnical diamond drill bit (cut hard rocks faster)

3. Require less push, resulting in a more accurate drilling

4. Precise, vibration free drilling for straighter holes

5. Less fuel consumption, rod wear and core barrel wear of this geotechnical core drilling bit


Our diamond drill bits are used for hydroelectric exploration, hard rock drilling, metal exploration, coalfield mining, geological exploration, water well drilling, hydro power and water conservancy, water and electricity building, construction industry of road, bridge, railway, and building, etc.
