Definition

1. Noun:
   • A hand tool for boring holes: A "screw auger" is a specific type of hand-operated tool designed for drilling holes, typically in wood. It features a spiral-shaped metal shaft (the "auger" or "screw") that pulls the tool into the material as it is turned, removing shavings to create a clean hole.
