Auger drilling is a method of drilling in which penetration is accomplished by the cutting or gouging action of chisel-type cutting edges forced into
the substance by rotation of the auger bit. Augers are designed for degasation of coal wells both with flushing and without it. Augers are used in many types of drilling rigs.
The body of the rod is heat treated and quenched adding to overall wear resistance of the drill string.
