I propose a copper pipe cutter of the traditional wheel type design. The difference is that this cutter has a wire brush head that cleans the pipe as you cut it. Allowing you to save time by cutting and cleaning for soldering in one single operation.

You mean cleaning in preparation for
soldering etc? This sounds like a jolly
good idea to me. [+] |

Wire brushes tend to have bristles that are too stiff for this application, steel wool works best to remove the oxide film. Maybe you could modify it to hold a piece of it steel wool instead of a brush. Incidentally, common code of practice for cutting copper pipe in Australia recommends the use of a hacksaw instead of these cutters as they tend to reduce pipe diameter, even after using the provided reamer to debur it. Of course if you are not a licenced plumber, go nuts! |

The most common type of pipe cleaner in the US is a Wire Bristle cleaner(it is a made for purpose piece) Or a water proof sand paper. I have only ever seen saws used during the installation of plastic pipe here. Pipe cutters are the norm here. |

Common practice is not always best practice. Never use a saw to cut any pipe that will carry water, gas (including air), or air conditioner refrigerant The small bits of metal or plastic (pipe dust?) get in the line and can be carried to and jam or even damage valves, controls, handling equipment,and especially AC compressors. This does not apply so much to drainage and sewer lines.Properly used a cutter will not reduce inside diameter, over tightening and forcing the cutter can distort the pipe, you can actually increase the I.D. with a reamer or de-burrer.
Be that as it may or may that as it be, I woder if you'd get enough spins with jhomrighaus's combo tool for the brush to do enuff cleaning to make much difference. |

The brushes could be made to counterrotate. Four or five
spins per revolution should scour the oxide layer right off
by the time the pipe is cut. A quick scrub of the inside and
you're done. |
