The new venturi RC drill bits are versatile and can be used in both soft ground and hard rock. This presents a huge time saving compared to air core drilling, as there is no need to swap tooling for harder ground. Venturi bits are also not hindered by water in the borehole: consistently high airflow is able to flush out water-logged samples.
