We would like to buy a couple 8 1/4 saw blades for new Dewalt 7485 table saw. I have been looking at several brands and see that many use the Diablo's in most Youtube video's.
I read the riving knife is .063 thick and the kerf on the blade must be bigger than the knife.
I would prefer to go with recommended blades for the Dewalt just for the price difference, although I would certainly spend a little more on the Diablo if they last a bit longer and make cleaner cuts.
This saw came a 24 tooth blade. We read that the factory blade will not be the greatest and a 40 tooth is more a combination blade for just about everything else.
We would like to get a 40 tooth and possibly a 60 tooth to have on hand for the different uses making cleaner cuts.
Our plan is to make some bookcase type shelves, corner cabinets, along with a wall unit in the future.
We are thinking about making all these things out of pine.

Looking at the diablo 8 1/4 inch 40 tooth blade on home depo's site, Model # D0840X I see this under the reviews.

Will this be safe to use on Dewalt's DWE7485? Blade thickness is the same size as the riving knif...

Blade thickness is the same size as the riving knife, .063".

    I have this saw and am going to buy this blade.
    The manual states...
    "The riving knife provided with this saw is marked as follows: 0.087" (2.2mm) thick riving knife. Only for use with 8 1/4" (210mm) blade with 0.094" (2.4mm) min kerf width and 0.079" (2.0mm) max body thickness"
    So, the riving knife is 0.087" thick, not 0.063". Both the guard splitter and the riving knife do actually state the above on them. With this blade's kerf at 0.094" and body thickness of 0.063" (< 0.079" max), the blade is within the table saw specs.
★★★★★★★★★★3 out of 5 stars.

not compatible with DWE7485
I am sure this is a great blade, I always see Diablo blades used on youtube videos and figured I would use one on my saw. However, the instructions specify not to exceed 0.063" and this is too thick.
Tried looking online to see if there are wider riving knives but have not found anything.
Too bad.

We do realize, this post is now at least 2 years old and the other 10 months old. We figured our DWE7485 would be the same. Not looking at this thou. We just bought this saw a couple weeks ago and not really sure what extra blades to buy now
In the manual I have, it reads the riving knife is 1.6mm which would be .063 no ?
Yeah, I will say it. We are really confused on what blades to buy now if there are no wider riving knives to use with different sized blades on this model saw.
