HARDWIN 7-1/4 Inch 40T Framing Circular Saw Blade 3-Pack, for Cordless and Corded Saws, Wood, Plywood, OSB and MDF

I grabbed these up when I saw them as usually the value 3-packs and such are 24 tooth and more appropriate for general rough cut framing. These being 40 tooth will make good clean cuts in plywoods without tear out. I plan to save them for that but they'd work well for cross cuts where your wanting a cleaner cut over the speed of a rip or framing type blade. Perfect for a nice clean look cutting off all the ends of deck boards in one long cut the length of your deck.
Also they're thin kerf blades which are great in slightly underpowered cordless saws and the ATB -alternating tooth pattern always makes a cleaner cross grain cut.
Good blades at three 40 tooth for $25. Definitely saving them for breaking down nicer plywood that's not practical on the table saw. That pretty much requires a circular saw which is where these blades will do a fine job.

I was skeptical. Thin Kerf blades have a bad habit of vibrating/oscillating such that they very rarely produce a narrow Kerf, in fact they often leave a cut that looks like a regular blade. Looking at the large cutouts in the blade, I thought that can't help things. I like the weight. I just got a brush less portable circular saw and love it's light weight and this doesn't add much to it. But I needed to put it to the test. The worst case scenario..... Rip Cut a 2 x 6 piece of Doug Fir. It cut smooth with no squealing, vibrating or singing. I was also surprised the blade was still cool to the touch. And as advertised, a nice thin Kerf.

This is a great saw blade. Love it.

Excellent quality and price for around the house use.

I’ve been using these Hardwin circular saw blades for a bit now and I’m impressed. They cut well and quickly like a hot knife through butter. They have a thin kerf, so you get clean cuts with less effort and more cuts per battery. I didn't notice any wobble and it had, minimal splintering. With the cutouts, the blade also weighs a bit less, so your saw becomes a bit more maneuverable and less tiring, though with a heavy battery in the saw if that's what you're using, you might not notice much difference. The blades have held up well. The price is good per blade and is a good value. They’re perfect for projects like flooring, deck board trimming or general cuts when you want a clean finish. They cut well and the price is good. I'd get these again.

Purpose for Product: Sizing plywood for hurricane storm shutters.

Product Inspection: Very sturdy box containing three 7and 1/4" Hardwin 40 carbide tooth circular saw blades. There
is a lot of extra packing between the blades to help protect them while in transit. Blades have a
lot of novel design features. Teeth are really sharp. Fits a Makita saw as it should.

Product Performance: Normally I am using a 24 T blade for general construction but changing to these Hardwin
40T for a better finish cut. Making 14 hurricane storm shutters from 1/2" exterior
plywood. These blades are a little lighter and thinner than I am used to. So far, they have
cut flawlessly with sharp clean edges, no kick back or significant drift.

Summary: Nice well-made 3 pack of blades that are holding their own so far. Found no defects.

I very quickly became a big fan of these blades. I have some lovely, expensive blades for my circular saws, but I found these were competitive with them. I have some doubt as to whether these will last as long, individually, but since a 3-pack is just over half the cost of one of the fancy blades, I think I'll still get more cuts per dollar out of these.
These blades are so thin and light that they change the experience of using a circular saw. The kerf width of 1/16" means only a small amount of material is removed. The result is smooth, easy cutting with a lot less clean-up. These blades also really do get more cuts out of a battery. Enough so, in fact, that I have started using a smaller battery size in my cordless saw to get the same amount of work done. The 40T combination blades leave a pretty good finish and still cut much faster than the 36T blades I was using before. I'm going to pick up some of the 24T for cuts that don't have to be as pretty. I suspect they will cut almost as fast as I can slide the saw.

These blades fit my Bauer cordless circular saw and they make excellent cuts on softwood. They may work great on hardwood also but so far I have only used them for construction grade dimensional lumber. The thin kerf is nice for minimizing waste and I think it helps the batteries on my saw last a bit longer. The saw doesn’t seem to work quite as hard and the blade leaves a clean/smooth cut surface. The all purpose 40 tooth blade works best for me as I tend not to take time to change blades based on the particular task at hand. Instead I make do with the blade on the saw and if that happens to be an all purpose tooth pattern all the better. These blades are similarly priced or maybe a bit less expensive than closest comparison at the discount tool store. I can’t speak to the longevity of the blades as I have only had mine for a short time but they seem to be well made.
