First off I bought this for some cross cut 1"x1" notches in soft wood, I have seen better cuts performed with a chain saw. Probably one of the worst preforming dado sets I have used. Including the 6" $20 cheapo set I have. Part of the problem may be the rake angle of the teeth, little or none, this might have been fine for some other application but not mine. It may not be obvious from the description but this set is of an odd design, the chipper teeth are very wide and then to achieve your desired width you almost always use the spacers. This seems to me like a way of saving money since they only have to have 3 chippers this way, if this blade made good cuts it would be a minor annoyance just because it is different from a normal dado were you just stack the appropriate chippers instead of having to mess with shims every time.
