DEREX 1340-350 DR

BIG AIR FOR BIGGER PROJECTS

Unlock the full potential of the Derex 1340 dual-rotary drill with a 350 PSI air compressor. The Derex 1340-350 gives you the ability to run larger DTH hammers, drill larger holes, and maintain strong air velocity as you push deeper into the formation. When the job calls for more than mid-range capability, the 1340-350 DR steps up.

The Derex 1340-350 DR is the perfect solution for bigger water well, geothermal, RC exploration projects, and harder rock. Take the stress out of drilling through difficult overburden, drill and set casing at the same time with the Derex 1340-350 DR.
