Engineered to handle the speed of geothermal drilling - drilling multiple borings per day as compared to a single hole during a multiple-day process -  DRILLMAX® geothermal drilling rig exceeds expectations in tough conditions. While geothermal drilling tends to prioritize overall rig size and weight, drilling speed, and cost per foot, options such as sandline winch or pipe spinner systems can be added to minimize equipment on the geothermal drilling job site.

  • DM250: suited for residential geothermal drilling or small commercial jobs.
  • DM450: designed for large residential geothermal drilling or commercial jobs.

“The DRILLMAX® geothermal drilling rig took a beating but got right through it. We doubled our production speed with the stroke and pump.The way she forces plastic clay out of the hole was pretty unbelievable. The 20-foot stroke and speed of the tophead means it goes faster for a longer distance, good for plunging clay out of the hole." - Joe Dalba, partner, Island Geo Drillers, New York
