They make wheels for that? My roomates once got me into taking stainless wire of about 1/16" thickness and making "springs" from it, then cutting them and making chainmail type stuff. I know, I know, but it was something to do and you'd be surprised how much that stuff sells for. Anywho, I couldn't cut the stainless with anything but a giant bolt cutter and even then the cuts would be nasty and unsuitable for wear. Some said that they used dremel discs but only got a little ways before the disc had to be discarded and thrown away. I wouldn't figure them to be up to the task of cutting 1/4" steel! If I trade, I'll give that a try before reading for the grinding cutter.

I've seen those burr cutters in action when I had a friend retap the footpegs on my motorcycle, amazing little devices! Just stuck it in the hole and spin it around the hole a few times, was smooth as a babies butt.
