Rated to 1000 linear feet(305m) of core drilling using N series tools.

FRAME AND BASE The drill frame is a weldment, constructed of heavy wall rectangular steel tubing, with sufficient strength and rigidity for heavy duty use.
POWER UNIT The basic D-50 Magnum unit is powered by a 4-cylinder diesel or a 4 cylinder turbo charged diesel engine.*  Electric starting and engine instruments are standard. *Other engine options are available
CLUTCH AND TRANSMISSION Clutch - 13 inch(330mm) automotive type. (60HP gas engine uses 11 inch(279mm) clutch)

HYDRAULIC SYSTEM On the D-50 unit, oil is supplied by a heavy-duty gear type two-section pump rated at 19 GPM(72 l/min) and 24 GPM(91 l/min) at 2400 RPM. Maximum operating pressure is 2300 PSI(15,513 k Pa). The pump is gear driven from the engine accessory drive or from the front crank shaft.

The hydraulic valves are stock sectional body directional control valves with an intregal non-adjustable relief valve. All controls are conveniently located on a single console for ease of operation.An optional regenerative spool can be provided for the main feed valve providing a high speed spindle lift as well as normal operation.

AUGER ADAPTER A heavy duty universal joint which mounts to the spindle with a single nut is provided for ease in hook-up and adjusting for misalignment. All components are sized to withstand torque and axial loads encountered under most drilling conditions. 1-5/8"(41.3 mm) female hex is standard, other sizes available.
