Mud system, top head travel speed, and rotation speed and power combine to quickly conquer clay or cobbles to increase production and profit. Engineered to handle 4-inch to 12-inch wells up to 1,000 feet, tailor the DM450 water well drill rigs to your specific geography and drilling preferences from a wide array of drill rig options. Choosing from an assortment of standardized options minimizes maintenance and makes repairing your water well drill rigs from the field possible with a phone call to our team of expert service technicians. Owners describe their DM450 well digging machines as “stable” and “stout,” praising its simple operation for making it easy to train new operators.

  • Increase production drilling larger wells with the small water well drill rigs easily maneuvering on job sites. The DM450 drill truck provides ample head feed speed — activated with a fast feed circuit — to flush the cuttings out of holes drilled in sand or clay, providing a clean hole to drop well casing or cathodic protection anodes. The water well drilling rig for sale also features the top head rotation speed needed to handle tricky formations — such as sticky clay.
  • Expand access choosing from multiple mud pump and air compressor options to configure the water well drill rigs for specific geographic areas. Some options, such as sandline winch or pipe spinner systems, can be added to minimize equipment on geothermal drilling job sites.
  • Ease operation with engineered design and modern construction, maximizing power to quickly and easily complete jobs while streamlining maintenance and troubleshooting. The control panel with its durable, mechanical controls, simplifies operation. The table assembly — with an opening to handle up to 16-inch casing — is positioned further back from the water well drill rigs, making it easier to handle tooling and set casing.

Armed with the fast head feed speed, many owners of DM450 water well drill rigs successfully complete water well drilling, geothermal drilling, or cathodic protection drilling with the same machine.

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 water well drill rigs 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 well digging machine is constructed consistently and tested thoroughly to ensure easier service support.

Applications


DM450 completes residential to agricultural water well drilling.

Water Well Drilling

With business ranging from residential to agricultural water well drilling, from 4-inch to 12-inch wells, customer praised the DM450 drill rig for completing the small wells just as easily as the big wells with less downtime than his previous rig.

DM450 makes quick work of geothermal drilling in Rocky Mountains.

Geothermal Drilling

Keeping up the “geo-pace” required drilling multiple borings per day in the Colorado mountains, installing geothermal loops. Customer claimed their DM450 drill rig outproduced the combined footage of three other rigs on the geothermal drilling job.

Cathodic Protection Drilling

A southern California customer drills cathodic protection holes for power utility companies. Local drillers in the area were completing one, 500-foot hole per week. Upon purchasing a DRILLMAX® drill rig by Geoprobe® and completing training they were able to complete one, 500-foot hole in an eight to 10-hour day, increasing cathodic protection drilling production for the utility companies.
