Hydracore 4000

The Hydracore 4000 is the most powerful drill Hydracore makes

Hydracore 4000

The Hydracore 4000 is the most compact machine of this capacity available.  The main difference between this machine and the Hydracore 2000 is that the 4000 has a P size head and either 200 or 250 HP.  This extra power and the bigger head gives the machine very high capacity, while remaining very portable.  It can drill to depths that would normally only be possible with a big truck mounted machine, but the Hydracore 4000 is light enough to be flown into very remote sites by helicopter.
