I assume these are 12” blades. ON the right:The red one is 44 tooth Freud Diablo general purpose should do the job well.
The other in the front seems to be a laminate cutting blade. It will give you smooth cuts on wood but is not the most efficient blade for that.
Not sure the model of the saw on the back but it should work for your purposes well too.

I agree the Diablo will work well for what you are doing. The blade on the left appears to be rusty. If this is the case trash it.

Hard to say for sure that the blade on the left is rusty—the brown stuff may be pitch from the wood. If that’s the case then you can clean it. A general purpose blade with relatively large gullets (to clear the saw-dust) should work well. If I had to choose from the blades you are showing, the Diablo is probably the best.

Actually, that’s not rust, it’s residual yellow paint, apparently the blade was painted on the edge, much like the one on the top right.

The blade on the top right looks to be a DeWalt construction blade, probably the 60 tooth DW3126 by the tooth shape and spacing. The one on the left, if it had a painted yellow rim, would be another DeWalt construction blade. Both of those are designed for clean crosscuts in construction lumber. In general, higher tooth count means cleaner cut, while a lower tooth count will be a bit faster. Garden beds don’t need a super clean cut like when installing interior trim and moldings, so for what you are working on, the DeWalts and the Diablo would all work just fine, so pick whichever is the sharpest.

First thing I would do is clean the blades. Removing resin build up will help blade performance and you can’t know if the teeth are actually sharp until that resin is gone. If none are sharp after cleaning, all three appear to have enough carbide to be able to be sharpened once or twice. A reputable sharpening shop will let you know and be able to get them all sharp for far less than a single new blade.

The bottom right blade looks to be a high tooth count (100-120) blade intended for cutting laminates or plywood. Not the best choice for what you are doing.

Now that you say that, the blade on the left (which is currently on the saw) has this etched into the side…

Based on your post, I thought perhaps this referenced a DeWalt 3416 blade, but I can’t find this model #. I presume the “80” is the tooth count?

Yes on the tooth count. If it’s a DeWalt construction series, the tooth shape is consistent with their 80 tooth blades. 3416 is not a valid current DeWalt part # and I don’t find reference to it anywhere, the current 12×80 is model# DW3128. It’s possible that 3416 was a promo combo blade pack that included a couple different blades or the 3416 could also maybe be a purchase or sharpening date (3/4/16)

I have the same MS and I would guess the top right was the one that comes with it standard.

You may try them out to see which one gives you the best cuts for the material you’re cutting. I have a Freud D1280X on mine currently. But I’d probably switch it out for a 40-60 tooth blade for the jobs you’re doing.

I like Freud blades as well, good blade for the money. I agree with what a couple folks above said, you don’t need the most expensive 80 tooth blade to cut cedar. Save some money and go down a tooth count or two.

Agree we don’t need a high tooth count for your application. 60 to 80 would work well.
If the Dewalt in upper right is sharp, it will work well. Same with the Diablo. If you can have it sharpened locally, even better.
If you’re looking for a new blade, consider Irwin Marples (made in Italy).
Member “knotscott” routinely says they are a very good blade for the price.

I doubt any of them are “sharp”. I do have a good local guy who can sharpen them.

Upon closer inspection, I noticed that the blade shown in the lower right hand side of my original picture is missing a tooth….I presume this renders the blade as garbage?

And, I also discovered another blade in my inventory, which has “Do not use on mitre saw” written on….Any guesses why this is the case?

One tooth missing won’t help, but it shouldn’t render the blade useless unless there’s other damage. Test it and see.

That blade shown above has a positive hook angle, so isn’t recommended for a sliding miter saw, but it should be fine on a normal CMS.

A good sharpener can replace a missing or chipped tooth no problem.

Miter saws produce the best cuts with a negative hook angle blade like the Forrest Chopmaster.

I realized after posting my last post that perhaps the “Do not use on mitre saw” blade could be for my table saw? (which I bought from the same person). My Miter saw isn’t a sliding model (although I wish it was). I wasn’t thinking about the table saw, as I have that in my garage & not in my shop (2nd floor shop), TS is over 500 lbs and that was a bit much to hump up to the shop, plus, for my work I don’t need it all that much and it’s fine below in the garage. (And the shop is tight enough that I don’t really have room for it, between the work table, 4 dedicated router tables, miter saw table, two sanders and a reciprocating saw that I have set up with dado blades.

I plan to take all these blades to my sharpening guys & see what they have to say about their condition(s) and future prognosis.

I would up buying a new DeWalt DW3232PT (80 T) blade for the miter saw @ Lowes because I wanted something usable right away, and my sharpening guy typically takes about a week to turn things around.

As knotscott suggests, a blade with a negative hook angle is best for the MS. A bit safer, too. A table saw blade’s tooth configuration has a tendency to climb. Sounds like you’re doing production so, you don’t want to be slowed down insuring against an errant saw.

I would guess the message written means that its not intended for pull backs on a sliding miter saw. On the finishing cut of a compound miter saw it will probably throw the piece out. The Freud in the middle right of the picture is a framing saw blade based on the shape of the teeth.

I agree with trying them out to see what they accomplish. You should at least make sure they have the right hole size.
