DM450 for deep water well drilling, geothermal, and cathodic protection now comes on an automatic truck chassis to further simplify mobilization.

DM450 for deep water well drilling, geothermal, and cathodic protection now comes on an automatic truck chassis to further simplify mobilization.

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 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 rig from the field possible with a phone call to our team of expert service technicians. Owners describe their DM450 as “stable” and “stout,” praising its simple operation for making it easy to train new operators. 

  • Increase production drilling larger wells with the compact machine easily maneuvering on job sites. The DM450 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 rig 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 rig for specific geographic areas. Some options, such as sandline winch or pipe spinner systems, can be added to minimize equipment on geothermal 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 rig, making it easier to handle tooling and set casing.

Armed with the fast head feed speed, many DM450 owners successfully complete deep water 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 service support nearby for your routine maintenance or more in-depth 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 deep water well drilling rig is constructed consistently and tested thoroughly to ensure easier service support.
