I once dreamed of getting a set of Fish Wave Forstner bits for woodworking but for the price I was able to get them despite their high quality just don't warrant I came across serrated forstner bits, essentially the same design, these forstner bits cut clean smooth holes for a long time. I actually bought a 7 piece set but I need some larger sizes to make a spice rack for my wife. . Let me tell you that this is the same quality I expected from Freud. They are high quality and durable and the price for the quality you get makes them even better. Now I can't compare them to Fisch Wave bits, but I can say they last much longer and hold their edge much better than any other CMT or similar Forstner bits I've owned in the past.
