I'd been using a regular saw blade blade backwards on my radial saw. It was adequate but generated a lot of dust. The foam cutting blade cuts more easily, makes a smoother cut and makes no dust. Note that when I set up the saw to rip, it grabbed the first piece and shot it across the workbench. I had to make sure to keep a firm grip on it. I did not need the provided stick-on plastic rip fence. My only complaint is that the blade comes with protective rubber guard around it. I found the guard to be flimsy and the blade cut right through it when I tried to re-use it. It would be better if the blade came with a protective storage case. Still, I think this is a great blade.

This is a great blade if you are cutting a lot of foam, or if you really care about making a smooth cut. I'm in the latter category. With 'lost-foam' metal casting, the finished result is only as good as the original foam model. This blade produces a much smoother finish than my synthetic diamond blade as can be seen in the photo. The only imperfections are tiny pits where a small fragment of foam was pulled out. The resulting bump in the casting can easily be filed or ground down. Another advantage is that the saw blade makes a very narrow cut and produces almost no dust. I don't know how I ever lived without one.

This brade arrived is great shape. Enclosed with it was a metal shim to affix to the leading edge of the fence of a table saw. This was a nice bonus. This was the first time I have cut foam board on my table saw. I probably would not have considered the width of the blade being a factor. But, this blade is a factor, since it severes material, rather than remove it (general speaking). So, you set up the included space on the front of the fence, so the trimmed material has some space to bulge out on the rear of the fence (after passing by the cutting edge of the blade). If you need clean precise cuts in foam board, this blade works very well, and I recommend it. I set this up in a Bosch 10" table saw.

I used this blade in a table saw to cut 1.5 and 2 inch XPS. It lived up to the claim to cut cut cleanly without creating confetti, very square. clean cuts, and it was possible to slice slivers off pieces. The saw motor struggled when cutting 2" XPS; I see now that the manufacturer recommends 1.5" as the max thickness for XPS. The blade is pretty fussy about work alignment; very easy to bind and kick both with and without the sub fence provided with the blade. I will continue to use it but likely won't buy another at the current price (may not have to, doesn't seem to wear). Definitely a specialty tool and probably worth the price if you work with foam board every day.

I am insulating the space where the floor joist meats the rim joist. So I need lots of pieces 14-1/2" wide. I put this blade in the table saw, and ripped them from the length of a 4'x8' sheet. If you have ever done this with a standard saw blade, you know the mess it makes. Not with this blade. It is like cutting it with a knife, but much easier. Once I have a bunch of strips cut, I move the blade to my sliding miter saw. This lets me cut the pieces to length. Because I have a brick basement, the length needed changes just slightly as I go along. This lets me make fine adjustments, saving me a lot of expanding foam or calk. When using the rip fence on the table saw, make sure you use the included spacer, or it is going to bind up every time. Because you are not removing any material, but are instead splitting the foam, it takes more room to get by the blade after it is cut. Without the spacer, the foam would get wedged between the blade and the fence.

If you have a lot of foam to cut and don't want to be covered in foam dust this is the way to go. Yeah the blades are a bit pricey, but you will probably never need to buy another blade to cut foam again. The cuts are smooth and there is very little dust when cutting compared to typical saw blade. There really are not any teeth on this blade, it has what looks like knife edges. It slices more than cuts through the foam. I tried using fine and course blade and they both create a lot of static foam dust. This is much nicer and cleaner. Cutting is easy, but on you have to be careful that the blade does not bind or it will kick. The blade comes with a strip of plastic that you use to keep a 1/8" or so gap between the blade and rip fence. The instructions recommend to not cut against the rip fence and you use the space or free feed the foam without a fence and use two people. Before using on table saw with a fence make sure the fence and blade are parallel or they diverge a small amount. If it pinches at all it will bind and kick.
