When I first started doing fine wood working about 4 years ago, I bought a dado set for about $50.  Well, as you can imagine, you get what you pay for.  I had to have a filing shop match the cutters up so I could get close to square cuts.  When it was time to move up, I purchased this product and have been extremely pleased with it.  I decided to give this set a try as I had purchased a Freud 60 tooth blade and it worked wonderfully, with no chipping on plywood or any of the solid woods I used.
