Bit broken on FIRST use. I did what you're supposed to do and just made light passes with White Pine, shaving a little bit at a time. When I pull the racquet out I see that one of the teeth is bent/broken. Even after more than an hour of setting up the milling bench, this was the best "match" I could get with the two boards. It's not even close to the set. I have used many bit sets for milling in the past and have never seen such an uneven "matched pair" of bits. just look up Two differently curved blades, they don't go together at all. HORRIBLE product, DO NOT BUY!
