The lip and spur drill bit is a variation of the twist drill which is optimized for drilling in wood. It is also called the brad point bit or doweling bit.

Conventional twist drill bits do tend to wander when presented to a flat. In wood, there is another possible solution, that used in the lip and spur drill (Brad Point). The center of the drill bit is given not the straight chisel of the twist drill, but a spur with a sharp point and four 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.  DeWalt Brad Point Drill Bits
