The hand auger is suitable for unconsolidated formations: sand, silt and soft clay. Stiff clays, hard materials and gravels are difficult or impossible to drill through and to remove (unless augering is combined with [[percussion - general|percussion]]).
Another option is to use the well casing used as support for the borehole as the permanent casing (direct installation), although in that case a gravel pack can not be used.
===Suitable conditions===[[Image:Auger drilling in temporary casing1.jpg|thumb|right|250px200px| Auger drilling in temporary casing]]
Augers can be used up to a depth of about 15-25 meters, depending on the geology.

===Construction, operations and maintenance===
It takes quite some expertise to drill a completely straight borehole.
* The tools for Hand augering can be made in local workshops.
