What is a "spade bit"?

A spade bit is a type of drill bit with a flat, wide blade that is used to drill large, rough holes in wood. It has a pointed tip to help guide it into the material and two flat cutting edges to clear out the wood as it drills. Spade bits are commonly used for tasks like drilling holes for pipes, electrical wiring, or large fasteners. They are effective for quick, large-hole drilling but may not provide the cleanest finish compared to other types of bits.
