This is frustrating because most of the Amana bits I have work very well. The cut quality is much better than the cheaper bits. But I bought three of these, and even on very slow, flat, conservative settings, I can't stop myself from breaking them. It's even more frustrating because the $14 Tamko bits on Revain are the same 1/32 size with the same cut settings and I never break them. They just don't leave a very clear finish. Why doesn't the cheap $14 bat break, but the most expensive $45 bat…
