The Discovery EF50 and EF75 are considered the most comprehensive drills in the diamond core drilling industry.
Both the EF75 and EF50 come equipped with Cummins
diesel engines, and feature heavy duty construction.
This makes them perfectly able to reach depths of up
to 5000-7000 feet NQ2.
The Discovery EF75 and EF50 drills weigh just over 20,000 lb.
They can be transported by truck to the drill site.
