An excavator auger is a drilling attachment that is used with an excavator to bore holes in the ground. It is typically used in construction, landscaping, and agriculture for tasks such as installing fence posts, planting trees, and drilling for soil samples. The auger consists of a rotating drill bit that is attached to a shaft and powered by the excavator's hydraulic system. The excavator operator controls the speed and direction of the auger, allowing for precise drilling in various soil types and conditions. Augers come in various sizes and styles, including rock augers for drilling through tough terrain.
