    Which circular saw blade?

    Hi,
    I mainly want to work with hardwood and birch plywood, and would like to purchase a good quality general purpose blade for that.
    Which one of these two do you think will be better? (I have the same Makita as you – the 5903r
    https://mechanicfaq.com/7-1-4-circular-saw-blades/).
    I don't mind the thicker blades, as they'll probably be more stale. But what about material and longevity? Are TCT blades the best? (Can't find any info about the DeWalt blade material... is this a bad thing?)
    How about the saw tooth angle? Does this make a difference if it is 10 or 15 degrees?
    How about anti-stick coating (the "orange" stuff from CMT)? Is this marketing? Or does it improve things?

    Re: Which circular saw blade?

    Welcome to NCWW. You're not looking for table saw blades, but 7 1/4" d circular saw blades correct? Here's some info about table saw blades but it's also applicable to circular saw blades.

    https://www.rockler.com/learn/choosi...-your-project/

    Many saw blades are coated with teflon for various reasons (CMT is orange, Freud is red). These DeWalt blades are affordable but they're for general construction use.

    Re: Which circular saw blade?

    Welcome aboard Xonsttt! Why not take a minute and start a new thread and tell us about yourself, that we might get to know you a little better. You are now a part of our vast family! Blade nomenclature is for different purposes and finishes. I prefer and use Freud blades in my shop. One of the benefits of coatings on the blades is it helps prevent rust. I have a high end Forrest blade that rusts rather quickly. I very seldom saw any plywood, so I would be a poor teacher when it comes to blades. The sharper the hook angle, the better that blade will rip a board, and greater hook angle produces a poor crosscut. Blades for miter saws have little to no hook andles as a crosscut performs better with little hook. A triple chip blade will leave a smoother cut in general, and usually cost a little more than an alternate top bevel tooth blade where one tooth bevels right, the next beveled to the left. A little better finish blade would be an Alternate Top Bevel (ATB) blade with a raker tooth between. In general, the more teeth, the smoother the finish. With plain steel blades, there are very fine tooth blades in 7 1/4" made for cutting plywood. The problem is finding someplace that can file and set these blades, as there are few sharpeners that do these blades anymore.
    Experience is a hard teacher; she gives the test first, and the lesson later.

    Re: Which circular saw blade?

    On my 7 1'4" saw, I run Freud Diablos from Home Depot. For ripping and framing, it's the 24 tooth. For plywood, it's either the 40, or 60 tooth blade. The 24 tooth is often on a BOGO sale. That's when I buy them. Once Irwin offered a free blade for your old one. Turned in a Diablo. Went home and mounted Irwin, and next day went back to see if my old Diablo had been trashed yet.

    I have the Diablo 60t. Very little chipout on ply or melamine, the lowest of any blade I've ever used. No regrets.

    +1 on the Diablo. Nice cut and mine last a long time.

    Re: Which circular saw blade?

    On a circular saw I wouldn't worry about anything but the tooth count.

    That Diablo 60T is a very good plywood blade.

    For xcutting hardwood I would save the 60 and use a 24 or 48. They are rough cuts anyway, right?

    I don't think the teflon nor the tooth configuration is a deciding factor. For me, its the quality of the blade: flatness and amount of carbon.

    So you can't really be Freud IMO.

    Here is yet another endorsement of the Freud Diablo. I put one on my small Fuego circular saw, and the difference was dramatic.

    Re: Which circular saw blade?

    I have had very good results with Dewalt blades on a circular saw. I use the 40 tooth on my 7 1/4 and my 6" battery saw.
