A spade bit, also known as a paddle bit, is a type of drill bit that is commonly used for drilling large-diameter holes in wood. It gets its name from its flat, spade-like shape. The bit features a central point and two cutting edges on opposite sides, which help to remove material as the bit rotates. Spade bits are typically used with a power drill and are well-suited for drilling holes in softwoods, hardwoods, and various wood-based materials. They are commonly employed in applications such as drilling holes for electrical wiring, plumbing, and general woodworking projects.
