5 Factors to Consider when Choosing Underground Drilling

 · In underground drilling most of the time the holes are not as deep for example 200 meters instead of 1 000 meters. This may lead drillers to choose conventional drilling methods rather than using wireline drilling methods. The thinner kerfs found in core bits used in conventional drilling can lead to a better rate of penetration.
