An auger is a tool used to bore holes efficiently and effectively. It consists of a rotating metal shaft with a blade at the end that scrapes or cuts the material, and a spiral-shaped flighting that rotates to scrape, cut, or siphon out drilled materials. Augers can be found for many different drilling purposes, with each version designed to work with specific materials, surfaces, or other requirements. There are different types of augers, including wood augers, expansive auger bits, and metal-cutting twist drills. Augers are used in a variety of applications, such as drilling holes in the ground for construction projects, planting trees, and ice fishing. They are also used in industrial applications, such as drilling holes for solar posts, telephone poles, and deck posts. Large augers are used to drill holes that can be filled with concrete, wood, steel, or steel-reinforced concrete piles, creating building supports that distribute the load from the surface to a depth more capable of sustaining large buildings and structures.
