Which tool is commonly used for cutting copper pipe?

A pipe cutter is the most effective tool for cutting copper pipe because it is specifically designed for that purpose. It features a sharp cutting wheel that can easily and cleanly cut through copper without leaving burrs or jagged edges. This results in a cleaner cut that is essential for proper fittings and seals when connecting sections of copper piping, which is crucial in plumbing applications.

Using a pipe cutter also allows for more precision in cutting, as the tool can be adjusted to the desired length and requires less physical effort compared to other tools. This makes it a safer choice when working with metal pipes, as it reduces the risk of accidents that can occur with other tools like hacksaws or hand saws, which require more force and can lead to uneven cuts.

Some other tools listed may be used for cutting materials, but they either do not provide the clean cut required for copper or can be cumbersome to use on small diameter pipes. The pipe cutter's design contributes significantly to the efficiency and quality of the work in pipe fitting.
