Drillers seeking rotary drilling options for larger, deeper wells in tough geologies choose the DRILLMAX® DM650 rotary drilling rig offering power of 28.5-foot stroke, 40,000 lb pullback, and 8,000 ft-lb torque to handle deeper wells along with weight of steel casing. Backed by our industry-leading service support, the rig offers additional advantages suited to your preferred drilling method, including:

  • For air drilling or down the hole hammer set up with up to 1000/350 air compressor
  • For mud drill set up with 6X8 piston pump along with a 4X3 centrifugal pump with ability to run either pump independently or supercharge piston with 4X3
  • Hydraulically retracting breakout table easily accessed from driller’s platform providing up-to 24-inch opening

Features & Options


In keeping with the DRILLMAX® reputation for simple operation and maintenance, the DM650 incorporates robust, straightforward controls, and durable components. Engineered to handle 24-inch wells up to 1,500 feet, tailor the DM650 rotary drilling rig to your specific geography and drilling preferences from a wide array of options. Choosing from an assortment of standardized options minimizes maintenance and makes repairing your air drilling rig or mud drill from the field possible with a phone call to our team of expert service technicians. 

  • Maximize production with your choice of rod carousel (3.5 or 4.5-inch) or single rod loader (3.5-inch) options designed to match your drilling needs.
  • Simplify setting wells using the breakout table which hydraulically retracts to provide a 24-inch opening, utilizes an air fork for fast and safe tripping out, quickly switches bushing sizes, and is located outside the drill mast for plenty of room to weld the well casing.
  • Tailor to your preferred drilling method with options for air drilling or mud drill. For air drilling, choose up to a 1000/350 air compressor. Mud drill options include a 6X8 piston pump and 4X3 centrifugal pump. Either pump can run independently or supercharge the duplex with the 4X3 running in front. 

Possessing power to reach depth with ability to support weight of steel casing, owners of the DM650 complete large residential, light commercial, and farm irrigation water wells or geothermal drilling jobs.
