Bought this set of cutters mainly because of the name Freud.  I've purchased a few freud products and have been pleased.  I'm equally pleased with this setup.  I installed these on my Dewalt DW744X table saw and also picked up a DW7444 dado throat plate.  Everything fit fine for me.  When you install these blades you have to remove the inside washer on the table saw I used the outside washer to replace it.  I replaced the outside washer with a thinner one.  Not a big deal for me because I had one in the shop.  You could go to the hardware store and pick one up.
