Video: DRILLMAX® DM250 - Features Walkaround

Big rig in a small package chews through tough clays

Drillers seeking efficiency for residential water well drilling or geothermal drilling choose the DRILLMAX® DM250 for its tophead rotation speed combined with 22-foot stroke all under Class A/B CDL requirements. Additional advantages of the durable, efficient mud rotary drill rig include: 

  • simplified maintenance and troubleshooting thanks to common components and above deck access
  • enhanced ease and comfort created by durable, mechanical controls and wide driller platform
  • increased production capability provided by head speed, rod loader, and helper side controls OR rod carousel carrying 8, 3-inch, 20-foot pipes

Customers claim the DM250 is “faster, easier, and doubles production — even in tough clays.”

Owners describe their DM250 as their most productive and versatile mud rotary drill 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 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 drill truck focus on drilling shallower than 300 feet, though the machine can exceed that depth. Key features on the drill rig 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 drill 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 rig is constructed consistently and tested thoroughly to ensure easier service support.

Applications


DM250 drill rig efficiently completes water well drilling

Water Well Drilling

Site conditions on a Michigan site in the past had required multiple days to drill water well to 160-foot. With their DM250 drill rig, customer claims they completed a water well in just five hours. 

DM250 small drill rig fits into tight spaces for residential geothermal drilling.

Geothermal Drilling

COVID-19 restrictions limited on-site personnel to two for the geothermal drilling job. Company owners completed 15 bores to 305 feet through tough, plastic clay 80 percent of the hole. One ran the DM250 drill rig while the other worked the mud cleaner getting loops ready for installation.
