What Drillmax does

Drillmax is a sub-brand of Geoprobe Systems (legal entity Kejr, Inc.), a private US manufacturer of water well drilling rigs and complementary tooling, founded in 1987 and headquartered at 1835 Wall Street, Salina, Kansas. The company operates four US service centers in Kansas, Florida, Pennsylvania, and North Carolina, and distributes internationally through a worldwide distributor network. Drillmax rigs — the DM250, DM450, and DM650 — are engineered specifically for water well, geothermal, and cathodic protection drilling applications and support mud rotary, air rotary, and sonic drilling methods. Differentiated mechanical features include a dual pivot jib (DM650), 6X6 all-wheel drive and 600/200 CFM compressor options (DM450), and a proprietary Spring Assisted Swivel Hoist Plug for safer pipe handling. The rigs are sold alongside in-house designed water well tooling (drill pipe, hoist plugs, adapter subs, concrete coring systems) and supported by same-day parts shipping and a customer-facing web portal, Geoprobe Connect, that provides access to machine service and order records.
