What tool is used to cut internal threads on an object?

Cutting internal threads inside a hole is done with a tap. A tap is designed to cut threads on the inside surface as you rotate it into the hole, usually after drilling a pilot hole and applying cutting oil. Different taps handle different depths of thread, and they’re used with a tap wrench or machine holder to gradually form the threads. Dies, on the other hand, cut external threads on rods or bolts; calipers measure dimensions; reamers enlarge and smooth holes without creating threads. So the tool that creates internal threads is the tap.
