Review on Freud Radius Rounding Shank 34 100 by Luke Cotton

I used this to give a 6061 aluminum plate a small radius. I've used it at about 50 linear feet and it's just as sharp as the day I opened it. I actually took a 3/16" radius cutter to redo some parts, thinking the router and aluminum would be a bad combination. A larger radius bit works just as well. If you use this on a tree it should last a long time. for a very long time.
