Freud Italian made Blades are awesome!! just finished doing some dados on the edge of 2 6 feet boards and let me say this blade performed great!! I used them on a 10 in Ryobi table saw, adjusted the depth, stack all the dado blades I needed and blast through it. you get in this package 2 main blades (one for each side of the stack) and then 3 stack blades that goes in the middle of the main two, you also get some spacer shims that you can place in between to make even bigger stacks. all this comes packaged in a very smart box that keeps your very nice Italian blade safely stored!!!! great product!!!!!!!
