DRILLMAX® DM650 can be outfitted for air drilling or mud drilling

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 1070/350 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.
With drill rig service shops in Pennsylvania, Florida and Kansas, you’ll have industry-leading drill rig service support nearby for your routine maintenance or more in-depth air drilling or mud drill remounting and refurbishment work. Our service technicians are backed by our team of engineers to ensure solutions not bandaids to issues. And our production processes mean your rotary drilling rig is constructed consistently and tested thoroughly to ensure easier service support.

Control Panel


DM650 Control Panel

DM650 Control Panel

Durable, mechanical controls neatly laid out on the robust, organized control panel on the DM650 rotary drilling rig includes engine monitoring, safety E-stop, hydraulic pressure gauges, friction control levers for mud pump and rotation circuits, and electronic throttle controls. Simple operation makes it easy to train new operators.


Top Head Carriage


Top head and drill mast features contribute to ability to quietly and smoothly drill deeper, bigger holes whether air drilling or outfitted as a mud drill.

Top head and drill mast features contribute to ability to quietly and smoothly drill deeper, bigger holes whether air drilling or outfitted as a mud drill.

Top head with 28.5-foot stroke, the carriage on the DM650 air drilling rig or mud drill uses rollers instead of slides, creating quiet, smooth head travel with simple maintenance.

  • long-lasting rollers are easily adjusted.
  • rollers permit fast and safe top head travel.
  • easy maintenance keeps rig performing like new.

Drill Mast


DM650 Dual Pivoting Jib

DM650 Dual Pivoting Jib

Rigid, stout drill mast provides 40,000 lb pullback with up-to 8,000 ft-lb torque and up-to 200 rpm. 

Dual pivot jib has primary and secondary winches. Primary winch swings and extends to the helper side. Secondary winch swings and extends to the driller side. Primary winch includes 17,500 or 12,000 lb options with the secondary winch offering 2,500 or 12,000 lb options. 


Mud Pump and Development Air Options


Available options for outfitting DM650 as down the hole drill or for mud drilling

Available options for outfitting DM650 as down the hole drill or for mud drilling

For air drilling or down the hole hammer, choose between 500/200, 600/250 or 1070/350 air compressor. 

Mud drill options include up to a 6X8 piston pump along with a 4X3 centrifugal pump. Either pump can run independently or supercharge the duplex with the 4X3 running in front.


Rod Carousel

DM650 Rod Carousel

Rod carousel capable of backfeeding while running drill pipe frees helper to complete other site chores. Rod carousel options available to accommodate preferred drill pipe size:

  • Carry 12, 3.5-inch pipes for a total of 240 feet with ability to backfeed. The optional rod box carries an additional 18 pipes allowing you to carry a total of 600 feet on the rig with these two options.
  • Carry 10, 4.5-inch pipes for a total of 200 feet with ability to backfeed. Optional rod box carries an additional 15 pipes allowing you to carry a total of 500 feet on the rig with these two options.

Table Assembly and Breakout Wrench
