Pipe Cutters are a hand tool that is most commonly used by Plumbers to cut piping. They are designed to create a cut that is clean and without jagged edges, compared to what can be done with a more traditional hacksaw. A Pipe Cutter is also able to cut the pipe quicker than a hacksaw is able to.
There are two types of Pipe Cutter and the one that you will need will depend on the thickness of your piping.
Thinner Piping should be cut with Plastic Tubing Cutters.
Thicker Piping should be cut with a Pipe Cutter that has a sharp wheel and jaw grips that are adjustable.
