FIELD: mining industry, particularly drilling assemblies adapted for lifting cut rock from well bottom to head thereof without the use of flushing liquids, compressed air and gas-and-liquid cleaning agents, particularly for creating drilling assemblies used for boring expendable, water, seismic and other technical wells.
SUBSTANCE: auger comprises body with rim, locking nipple and coupler welded to the body. One body end has boring for receiving bush rigidly connected with body. Bush has non-round inner section identical to locking nipple section and located at a distance from body end to provide embedding of lower locking coupler end in the boring between body end and bushing.
EFFECT: extended operational life, increased reliability of connection between locking members and auger body.
