Square cuts right out of the box. Good set of shims that made adjustments easy. The only thing I would like to have seen was the marking of the cutters (i.e. C, D, E etc). Other than that, this is an excellent product.

Review : ... I decided on the Freud based on the Freud blades I have own in the pass ... The blade setup guide is a very easy to follow showing all of the milling widths and the combination of blades needed. On my 5 hp Powermatic, I tested 3/4" oak, 5/4" poplar and 3/4" cherry veneer plywood all produced perfectly flat bottoms, no tear-out and cut your finger razor sharp edges. The set includes 6 shims that let you dial-in the milling thinness to match your plywood which is notoriously thinner then its stated size. I would suggest that you label the chippers and the shims as soon as you get them, this greatly speeds up the setup time. The storage case is a great bonus and holds everything very tightly. I would recommend this Dado set to anyone looking to produce professional results.

Review : I recently purchased a Delta contractors saw with the intention of constructing a set of shelves to place on a table to house my amateur radio equipment. The plan was to cut grooves in the end supports, Oak veneer 3/4" plywood, to receive 8 foot(!) shelves of the same material. Movable intermediate supports prevent shelf sag. I purchased this dado set locally and found some of the same challenges previously posted concerning the shims. I overcame them after a couple of false starts. Testing on scrap stock proved that the dados were smooth, straight and with perfectly a flat bottom. I proceeded to make the cuts on the shelf ends and they came out very well. Certainly these blades are worth the purchase price. I'm a happy camper. I may buy some plastic shims I've seen advertised elsewhere, but they too will slip into the arbor threads, I'm sure. You just have to be careful in the setup.
