I've tried one other blade but this was the best performer hands down. After making several cuts, even ripping 12 foot siding, this blade never slowed or loaded.

I put the blade on an old Craftsman saw to cut Hardie siding and trim. It cuts just as fast as cutting wood with a good blade. Dust is minimal compared to diamond blades and much faster. Excellent product.

I bought this blade because I like the 4x8 sheets of cement board siding. I sometimes use cement board under tile, but I don't do all that much tile work, but the siding is great -- pretty much impervious to water, bugs, etc. The only problem is working with it. I find that this blade cuts it with no problems, and an air nailer shoots nails into it just fine. Wear a mask when you cut it. There is some dust.

I would recommend this product. Cuts the hardie siding with ease and does keep the dust down. Not sure how long it keeps sharp as I am not done yet with the house, but so far, so good.

This blade, made specifically for cutting fiber cement boards/planks, has lived up to my expectations so far. I'm a homeowner, doing my own re-siding of my home with Hardiboard planks, and I'm only about 2/3 the way done. I've had to make a lot of cuts because of multiple sides, windows etc, and have gone thru several 'certified' Hardie approved (4 tooth) blades, i.e Freud, Irwin, but they DID NOT have PCD (polycrystalline diamond) inserts. Those blades, while holding up better than a standard carbide blade would, started showing signs of wear after about 30-40 cuts, shooting sparks and such.
I read about these blades by Hitachi (DeWalt, Makita and others also have them with PCD) and the review/price seemed to make the Hitachi the best value. Good value, doesn't mean cheap!
I bought the 7-1/4" and 10" variants of the this Hitachi blade, and have made hundreds of cuts so far, with no signs of degraded cutting ability.
I use the 7-1/4 only for my circular saw for ripping. As promised, and printed on the label of this 10" blade, you can gang together up to 5 planks to cut at one time...and it works flawlessly. I use a Bosch compound miter saw and it literally makes the cut so cleanly, even after hundreds of cuts, that I simply wipe the edge with my hand before nailing the planks up. No more using a knife to cut away the jagged edges left by poor quality blades.
If you're like me, you hate dealing with the dust of cutting fiber cement boards. If using a compound or chop saw, you will cut thru so fast, with so little dust, for some cuts and having a light breeze to take the dust from you, you'll be tempted to now put the mask on every time. Not recommended, but a testament to how much less dust these do generate.
I'm very happy with this product and will gladly pay the extra dollars for PCD blades like this Hitachi again if needed. Only way to go!
