Diamond drill bit for coalfield mining is generally used for deep drilling in soft rocks where drill bits are easily covered by slurry. Wire line drill bits are most commonly used in coalfield mining. Our specially designed geotechnical core bits feature fast speed and long tool life. These drill bits are usually hot press sintered or electroplated. The hardness of the matrix is HRC15-40.

Features

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

2. Maximize penetration rates with these geotechnical core bits (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 bits

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