Why Drill King?
Cylinderless Design
The N240 eliminates the traditional cylinder component, meaning fewer parts to maintain and simpler field servicing.
Massive Rotation Torque
20,000 lb·Ft (27,120 N·m) of rotation torque drives the largest-diameter bits Drill King offers through the toughest formations.
High-Volume Air Delivery
Up to 3,520 CFM at 200 PSI clears cuttings efficiently even at the largest bit diameters.
Flexible Top Sub Connections
Available with Hex 190, 210, 240, or 8-5/8" API REG top sub connections to match a wide range of large-diameter rigs.
Open or Cased Hole
Customizable configurations adapt the HADK-240 to open hole or cased hole projects alike.
Extended Component Life
Premium alloys and wear-resistant surface treatments extend tool life and reduce operating cost on the largest-diameter tooling.
