10 reviews for DEWALT Circular Saw Blade, 8-1/4-Inch, 40-Tooth (DWA181440)

  1. Larry Lee

    Just replaced my old carbide blade on my late Dad’s very old (antique) Toro table saw. The new blade is cutting smooth and clean. I could not find a 9″ anymore. So the 8 1/4″ will have to do.

  2. David Cuozzo

    I needed a new thin kerf finishing blade for my 10″ table saw for a project I am working on and saw the positive reviews on this Dewalt blade. They had a great price on the “old model” and it cuts clean and smooth.

  3. JimG

    Installed the blade on a vintage Craftsman radial arm saw. The improvement (old blade was just steel, no carbide) was dramatic.I’m more of a table saw guy. But with the cut quality with the new blade I will probably now do all of my cross-cutting with the radial arm, and leave the table saw for ripping only.

  4. Roger that!

    Perfect on my Makita table saw, works as advertised…produces great cuts.

  5. Pamela DeVack

    Was concerned about it not working with my DCS7485 Dewalt Cordless Table Saw. Called Dewalt support and lady said it wouldn’t work. But, that was incorrect. Thanks to a review from someone on here, I took a chance and it works perfectly, and cuts like butter.

  6. Tyberius

    Dewalt may not be the best blades in the world, but the run a pretty close second. The “red blades” are always sold out so i opted for these old reliables. Never over heated and cuts like it’s going through butter. MDF, 3/4″, even 1/4″ maple veneer. at the cost difference, these will be my go to blades when i need one in a pinch.

  7. Amazon Customer

    Cuts smooth, fast, no splintering.

  8. Kelly DeJong

    It’s a dewalt blade, it’s good. Only bought because my dewalt saw came with 24t blade, needed a finer cut and this works well, plus it’s harder to find this size blade

  9. David Tribble

    produces a smooth finished end-grain cut that is joinery ready – I put this in an old sears Craftsman chop saw that I have had for decades – made a new saw out of it. Very impressed

  10. Tom Dodd

    I’m happy with the saw blade, but extra happy that for whatever reason, Amazon charged me for one blade, which I feel is a good deal at $20, but sent me a 5 pack for that price. Christmas!
