A spade bit is a type of drill bit designed for drilling large holes in wood. It features a flat, paddle-like shape with sharp edges, allowing it to cut through the material efficiently. Spade bits are commonly used in woodworking and construction for tasks such as installing door hardware or running electrical wiring. These bits come in various sizes, typically ranging from 1/4 inch to 1 inch in diameter. They are compatible with standard drill chucks and can be used with both hand drills and power drills. Proper use of a spade bit can result in clean, precise holes with minimal splintering.
