The Diedrich Drill D-50 is an all-purpose drilling rig for environmental and geotechnical drillers to use for soil and rock explorations using augers, rotary tools or core drilling tools. The drill frame is a weldment, constructed of heavy wall rectangular steel tubing, with sufficient strength and rigidity for heavy duty use. It features 9,100 foot-pounds of spindle torque and 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. www.diedrichdrill.com
