MAXDRILL overburden drilling systems are designed for simultaneous drilling and casing installation in loose and unstable overburden formations.

They provide reliable drilling through difficult ground conditions, including formations with large boulders, while the casing is installed behind the drill bit to stabilize the borehole.

Available in various configurations to suit different DTH hammers, casing sizes, and drilling applications.
