The lip and spur drill bit is a variation of the twist drill bit which is optimized for drilling in wood. Conventional twist drill bits tend to wander when presented to a flat workpiece. In wood, the lip and spur drill bit is a solution: The center of the drill bit is given not the straight chisel of the twist drill bit, but a spur with a sharp point and sharp corners to cut the wood. The sharp point of the spur simply pushes into the soft wood to keep the drill bit in line.
