Replacement wheels are available for some of the pipe cutters. Over time, the wheel blade may dull meaning they do not cut through the pipe as effectively.
Most single handed pipe cutters, as well as some adjustable pipe cutters, have replacement wheels available. To find out if your pipe cutter has replacement wheels available check the information with the cutter. Replacement wheels often come in packs of three or four but are sometimes sold individually.
Different sized pipe cutters have different sized and shaped wheels so it is important to check that you get the correct wheel for your cutter. This is often represented by a code, for example PC316, which will be indicated on both the pipe cutter and the replacement wheels.
