Auger

AUG'ER

,
Noun.
An instrument for boring large holes, chiefly used by carpenters, joiners, cabinet makers, wheelwrights and shipwrights. It consists of an iron blade, ending in a steel bit, with a handle placed at right angles with the blade. Augers, made with a straight channel or groove, in some places, are called pod-augers; the modern augers, with spiral channels, are called screw-augers.
