High Penetration Wireline Impregnated Diamond Core Drill Bit
Introduction:
Wireline core drilling systems are used for medium to ultra-deep boreholes, which provides the most efficient core sample extraction from the rock mass without pulling the entire drill string. The rock sample is removed from the bottom of the hole in the inner tube assembly by an overshot on a wireline cable.
Main parameters:
| O.D.(mm) | I.D.(mm) | Reaming Shell O.D.(mm) | |
| BQ | 60.00 | 36.50 | 60.07 |
| NQ | 75.70 | 47.50 | 75.82 |
| HQ | 96.00 | 63.50 | 96.27 |
| PQ | 122.60 | 85.00 | 122.81 |
| BTW | 60.00 | 42.00 | 60.07 |
| NTW | 75.70 | 56.00 | 75.82 |

By developing a proprietary process of coating diamond bits while in the furnace, we has successfully created a chemical bond between diamond and matrix. The bond acts stronger than the diamond itself and provides higher diamond projection (up to 80% compared to 40% for mechanical bonding) for improved flushing, higher penetration rates, and longer bit life.
