High Penetration Rate Rock Drilling Tools PDC Diamond Core Drill Bit For Geological Exploration
NQ PDC Diamond Core Drill Bit for Sample Coring
1.PDC core bit is widely used in geological drilling, coal mining, hydraulic and hydopower engineering, and the construction engineering of roadway, rail and bridge.
2. PDC core bits use slot face discharge hole type. It’s often adopted in pdc bit, TSP bit, and has bigger flow capacity, which minimizes the occurrence of discharge hole blockage. It’s suitable for drilling in fractured formations where there is much flushing fluid and rock debris.
PDC core bit features
1. Good thermal stability;
2. High penetration rate;
3. Coring completely;
4. High resistance to wear.
5, The bits are suitable for soft to medium soft formation;
6, PDC cutters are arranged on the bit to improve the service life of the bit.
