I’ve been using a high quality dado blade made by a highly respectable company. I switched to this one because it was recommended by SawStop for my saw and keeps the blades from creeping closer to each other. My other one was kind of difficult to get adjusted for just the right width. This one has magnetic shims which make it much easier to get them onto the arbor without getting caught up in the threads. The white plastic spacers click into the outer blades and the cutters and they all fit together to keep everything where it should be and keep the teeth away from each other. It’s safer with a SawStop if the brake triggers because it’s all locked together. Other blades can shift after a brake firing which could cause teeth to hit each other and possible dislodgment of them and cause flying carbide teeth. Not a good thing. I’m impressed that this is the only European certified dado blade currently on the market. I guess there’s no American certification for dado blades that I’ve heard of but don’t know for sure. I like cutters are laid out for a smooth flat bottomed dado. The included guide for shims makes it easy to set it to just the right width. My other one had a guide too but it was always off a bit causing me to have to take it off and add or remove a shim. I got this on sale and it was an excellent price especially for the quality. I can sell my old blade because it’s in such good shape.

Before getting this set I had never used a dado stack. The value, not only in cost, but in safety and simplicity is so high. I like to build the stack on the arbor as to not damage the shims and bc they lock together it’s just a dream, this is the best innovation I think I’ve found in my experience thus far woodworking. The cut quality is fantastic so far. I’ve cut Oak, Pine, Ply, and MDF with zero issues and flat bottoms. Super recommend.

Great Dado set! Finally replaced my 35 year old Craftsman Dado with this one. I've only made a few test cuts but appears to work great, making clean cuts with no blade ridges or tear out. The shims are somewhat confusing which I'm sure I'll get used to. On the upside, the spacers do allow for a wider cutting range down to 32nds vs other sets which only go to 16ths. What's really nice is the locking spacers which allow you to put the set together with everything locked together vs installing each cutter one at a time on the saw.

I use cmt products quite extensively in my woodworking shop and am very satisfied with their quality and the wear and tear they can take and this new pro dado set they have come out with is top notch would recommend to everyone everyone looking for a quality tool to add to their shop.

I bought this to replace my older stacked dado set because it was not suitable for my new SawStop table saw; The old one had full size chippers which made it very massive. SawStop tech support informed me that with that much rotating mass, if the brake activated on the saw, there was a good chance that the arbor would actually bend from the rotating torque. This set weighs less than the SawStop branded Dado stack, (which retails for quite a bit more), so it should be okay. The locking mechanism is unique and kind of cool once you get used to it. It only took me two tries to " dial in " the right width for my application. Very nice. The only complaint I have is that the shims are not labeled for thickness; easy enough to remedy with a sharpie and a micrometer.

I think I read everything available on Dado’s for SawStop saws. In particular I have the Jobsite Pro. Since I really like CMT blades and I liked the increased safety aspect of the interlocking nature of this Dado set I landed here. I’m very glad I did. First off: this works great on this small saw. You can use it at its greatest expansion with the stock spindle nut and still have a thread exposed. Secondly, it cuts very well. So far in beach, oak and pine. The bottoms are not completely flat, but I think that this depends on how you have it set up. Still they are very good. Very little chip out. The setup instructions with this set are dead on accurate. Now: you MUST read very carefully the extremely fine print on how to set this blade up. The diagrams are only marginally helpful when combined with the text. It is NOT intuitive!!! The locking spacers in conjunction with the magnetic and non-magnetic spacers must be in the correct order in order to get the smoothest cuts, especially when attempting wide cuts. Getting used to just HOW to lock all the various blades, chippers and locking spacers together so that the teeth of EACH of them lines up optimally takes a bit of thought, time and some trial and error. If you’re in a hurry with this set, you won’t be happy. I’m thinking of getting a set of magnetic spacers, since the non-magnetics can slip and slide a bit during assembly which makes the whole unit difficult if not impossible to get over her arbor. Not a show stopper though. Oh- regarding cost, of course don’t forget to factor in the Dado SawStop brake cartridge. But overall for the cuts you get, the safety you definitely get, and the ability to use this without another arbor nut I think this is a great product that I’ve enjoyed using. When assembled correctly the Dado unit is rock solid, locked in (as promised by CMT) and works great.

Buy buy buy buy!!! Pay the money!! I am telling you!!! Pay the high price of these they are worth every penny. They lock into place, no movement. Safe AF!! Ask yourself what is your face, hands, eyes worth to you?? Because the old, non locking datto blades are so dangerous, after using these as as if we were playing in clown shoes using the old style

This is a well constructed product and with the plastic connectors that space the teeth properly, it is recommended. My previous form used the brass spacers and they’d always get caught in the threads of the saw arbor, making it difficult to assure a tight fit of the arbor nut. It finally happened that the blades loosened and shattered when the saw was shut off. Fortunately no injuries, but it definitely gave a favorable not to the safety version.
