An auger drill is a tool used for boring holes into the ground. It consists of a helical screw blade, known as an auger, which helps to remove soil or other materials as it drills down. Auger drills are commonly used in construction, gardening, and geological exploration to create holes for posts, foundations, or soil sampling. These drills can be operated manually or powered by machines, depending on the size and depth of the hole required. They are effective for various applications, including installing fencing, planting trees, and conducting geotechnical surveys.
