Cleaning the pipe before cutting prevents any debris from the abrasive cloth from falling into the tubing. Use a good tubing cutter. Use fresh blades that are tight in place. Go slowly to reduce the lip on the inside of the pipe. Only use a deburring tool when you can safely and confidently keep the shaving from falling back into the pipe.

Also, do NOT use channel locks to grip the pipe, as that can also cause kinks, and the bite marks from the tool can become potential leak areas.
This tool has to be the most popular modern method for swaging soft copper. Each head fits a different pipe size, and you simply pump the handle until the copper is fully expanded. Then, a simple release of the pressure allows you to remove the tool and get a good swage every time. This will prevent stress from being concentrated in one area of the tubing. Annealing copper is simply the process of heating up the pipe and letting it cool down to reduce its rigidity.
