A tapered reamer works great for deburring brake lines.
Rusty, thanks for the tip. I didn't have a tapered reamer, but I did have a 14 degree metal deburring tool for my die grinder that looks a whole lot like a small tapered reamer. I put it in my cordless drill for better slow speed control and it worked great. A file on top, taper the inside, and a combination of bench grinder, die grinder, and emery paper for the outer chamfer and I made four this morning with no do-overs.
How are you cutting the tubing? I use an ordinary tubing cutter with sharp wheels. It cuts the tube square but leaves a burr on the inside. I remove the burr with a hand held tapered reamer then flare it with my old flaring set I have been using since 1968.
Occasionally I will dress the end with a fine file if the tapered reamer leaves a burr.
Have never needed to chamfer the end or use a die grinder. If the end is square and the die will fit in it should be OK.
One thing I had to learn was not to press on the flare too hard. It is better if it is not quite finished, when you install it and tighten up the nut it will squash together and make a better seal.
