I don't know what all these reviewers that talk about chipped teeth are talking about? The chipperd have flat top teeth and the outer blades have beveled. As for perfectly flat bottom dados - no dado set makes perfectly flat due to the fact that there is space between the chippers and blades and as for the kerf ticks in the corner again this is how they are designed all dado sets to this. Ugh some people!! This set is perfect for the hobbiest and weekend wood worker for the price you can't get much better.
