I don't really know how many stars to give this set. I'm not happy with that because I didn't realize how small the Beats are, they're a child's size and I have a big Victorian back that I need to duplicate and these Beats aren't going to shrink, so to speak. But. If I had paid more attention to the features I would have known before I bought it, so I can't fault it. Anyway, I used a straight end router with about 30 linear feet of Douglas Fir and it cut clean and still sharp (cut was poor at first but I changed the grain orientation and then it cut clean). I would use them more often but I seem to have lost the tiny box they were in somewhere in my basement and now I can't find them. Will update as I use them more.
