The commonly used tool for cutting external threads on pipe is the pipe die. Pipe dies are specifically designed for this purpose, allowing the user to create threaded sections on the outside of the pipe, which are essential for making connections with other threaded components.

When a pipe die is used, it ensures that the threads are cut to a precise and consistent pitch, which is crucial for the proper fit and sealing of threaded joints. The use of a pipe die also allows for adjustments to be made easily should the pipe need to be shortened or modified.

While other tools such as pipe cutters are designed for slicing through pipe material, they do not create threads. Similarly, pipe reamers help smooth or enlarge the inside diameter of pipes to prevent burrs and rough edges, but they also do not address external threading. Pipe taps, on the other hand, are used for creating internal threads. Thus, in the context of creating external threads on a pipe, the pipe die stands out as the appropriate tool.
