What is a Jig

In simple terms, the jig is a tool that guides the cutting (or machining) tool. The most common type of jig is the drill jig, which guides the drill bit for creating holes at desired locations. Using drill jigs increases production rate drastically by eliminating the time spent using a square scriber, height gauge, centre punch, etc. The picture below shows the functionality of a simple drill jig:

Like drill jigs, welding jigs and wood working jigs are also used in industry quite extensively. Wood working jigs are useful for creating intricate wooden profiles.
