Simple operation and surprising power provide fast production with 22-foot stroke. Choose from a wide range of options, tailoring your DM250 to your geography and production needs. Selecting from standardized options reduces hassle of routine maintenance and makes possible repairing your rig from the field with a phone call to our team of expert service technicians. Owners describe their DM250 as their most productive and versatile water well drilling rig, praising its simple operation for making it easy to train new operators. 

  • Save money by mobilizing 200-feet of pipe while staying under class A/B CDL requirements, eliminating concerns over having enough 20-foot pipe to finish the job or having to find a CDL driver. The durable, mechanical controls stand the test of time, keeping you completing contracts rather than repairing rigs. 
  • Increase production thanks to the top head rotation speed combined with stroke for 20-foot tooling, quickly chewing up tough clays. Table assembly has clearance for 12-inch PVC casing and the holding fork and hydraulically-operated, adjustable breakout wrench make tripping out fast and safe.
  • Expand access with the small drill rig suited for residential work where limited access is a priority. No more worrying about tearing up driveways or yards makes this water well drilling rig a smart choice for everyday use. Set up with centrifugal or piston mud pump and development air to meet your job needs.

Many who use the DM250 water well drilling rig focus on drilling shallower than 300 feet, though the machine can exceed that depth. Key features on the water well drilling rigs for sale make for quick, easy work of 2-inch to 6-inch water wells.

With rig service shops in Pennsylvania, Florida and Kansas, you’ll have industry-leading water well drilling rig service support nearby for your routine maintenance or more in-depth rig 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 water well drilling rig is constructed consistently and tested thoroughly to ensure easier service support.

Control Panel


The durable, mechanical controls neatly laid out on the DM250 drill rig control panel include engine monitoring, a safety E-stop, hydraulic pressure gauges, friction control levers for mud pump and rotation circuits, and electronic throttle controls. Everything in front of you, labeled, makes for simple operation and easy training of new operators.

Top Head Carriage


Top head carriage uses rollers instead of slides on the small water well drilling rigs.

Video: DRILLMAX® DM250 - Top Head

Rollers for top head carriage on DM250 create 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.

Minimize time spent standing around waiting on cuttings to rise to top of hole thanks to the top head travel speed on the DM250. The fast travel time up and down the mast increases the uphole velocity pulling mud and cuttings up out of the hole. So rather than wasting time waiting on cuttings to come up out of a 300-foot deep well, you can move on to the next step.

  • significantly cut time to clear cuttings from hole with top head travel speed.
  • minimize time spent clearing mud and cuttings from hole to maximize production. 
  • trade less time standing and waiting for more time drilling and making money.
     

Mud Pump and Development Air Options


The DRILLMAX® DM250 drill rig by Geoprobe® can be set up with centrifugal or piston mud pump and development air to meet your job needs. Mud pump and air compressor options include 3L8, 5x5 duplex, centrifugal pumps and 85cfm development air compressor. The hydraulic power provides the ability to use multiple functions at one time.

The DM250 drill truck table assembly has clearance for 12-inch PVC casing. Table opening positioned outside rig permits placing casing without body contortions.

  • easily access table opening positioned at back of rig rather than struggling to reach inside rig.
  • contact casing while remain at control panel.
  • remove bushings to set up to 12-inch casing.

F600 model comes standard with a hydraulic table, featuring:

  • Bushing closest to mast incorporates hydraulic movement.
  • Table slips to clamp and hold up-to 6-inch steel casing tight.
  • Eliminates chattering pins in coarse sands and gravel for quieter job site.

Compact size and easy mobility mean getting to and into jobs fast and moving on to the next - whether off-road or a limited-access residential area - without worrying about having a CDL. Drillers enjoy the creature comforts of the factory 4X4 chassis, including air conditioning, cruise control, and bluetooth while minimizing fuel costs achieving 15 mpg on average. Clean layout of the deck, complete with access panels, makes for easier maintenance of securely routed hydraulic hoses from above the rig.

The newest model DM250 on Ford F600 incorporates a number of those requests, including:

INCREASED REAR OUTRIGGER STROKE by 10 inches, providing more clearance to push and pull conductor pipe.

BETTER GROUND CLEARANCE provided by pads sitting 4.5-inches higher and split shaft sitting higher, improving ability to access job sites.

IMPROVED HYDRAULICS including:

  • increased cooling capabilities.
  • adjustable holdback improving control of down-the-hole hammer when driving casing and finer adjustments to see formation change when completing gravel pack wells.
  • improved auxiliary hydraulics for increased flexibility when choosing rig options.

Rod Carousel

Safe carousel option promptly pays for itself carrying 160-feet of 3-inch drill pipe.. Eliminate worry whether helper will call in sick when you choose carousel option that shows up everyday. 

  • create opportunity to task helper with other site chores or run a one-man operation. 
  • pipe locks into position within pod canceling chance pipe falls out.
  • rotate carousel to place indicator arrow between grooves on base, push handle, and lock carousel into position for safe travel.
  • mechanical alignment of top head with rods using indicator arrow and grooves on base eliminates need for electrical sensor that could malfunction.
