A woodworking bit is a rod or spiral tool with a cutting edge at the end, used for machining through or blind holes.  Woodworking bit and woodworking end milling cutter are different in that there is no cutting edge on the side. In addition to the main cutting edge, the woodworking bit has a sharp countercutting edge on the outer edge, which is used to cut wood fiber and make the side of the hole more smooth.

Common drill bits include twist drill, woodworking drill, hole drill and flat drill.  Each has its own advantages and limitations.  

Woodworking drills have spikes in the center. The purpose of this design is to allow the drill to engage the wood before the cutting edge of the drill touches the wood, so that it is more accurate in positioning and the hole drilled is very round.  A hole drill is a professional woodworking tool used to drill holes in a pipe frame.
