How does a plumber typically deal with the restriction formed in a pipe by a pipe/tube cutter?

A plumber typically addresses the restriction created by a pipe or tube cutter by using a tapered reamer. When a pipe cutter is used, it can sometimes leave a burr or deformation on the interior edge of the cut, which can obstruct water flow. A tapered reamer is designed to remove these burrs and smooth out the edge of the cut, allowing for improved flow and preventing potential issues such as clogs or turbulence in the piping system.

The tapered design of the reamer helps to gradually enlarge the opening while cleaning the edges, ensuring that the pipe remains structurally sound and properly aligned for any fittings or connections that may need to be made afterward. This technique is essential for maintaining the integrity and performance of the plumbing system.
