The Sandvik DE881 is a heavy-duty multipurpose exploration drill rig and is the indrustry benchmark in performance. The DE881 offers more depth capacity in both diamond and reverse drilling when compared to its competitors. It is the most powerful drill rig in the Sandvik range of exploration drills and is recognized as industry leading when it comes to performance.

Advantages

  • The hands free rod loading design enables safe tripping of the rod string in and out of the hole, ensuring no contact is made with the drill rods
  • The system torques the rod threads to the correct torque increasing drill rod life improving productivity
  • The multipurpose capability for reverse circulation and diamond applications provides greater flexibility
  • The tray includes an onboard rod storage bin, the rod bin is constructed to hold diamond core rods or reverse circulation rods
