Customer Reviews

Hitachi 10 inch fiber cement saw blade
This is a great tool for cutting cement siding. I use mine in my radial arm saw and get very smooth cuts. With the radial arm saw I can cut the widest planks. The dust is much less than cutting with a regular carbid blade. I also use the 7 1/2 inch blade in a circular saw for rip cuts. I am also using Malco Plank Gauges for holding the planks during installation and they are very helpful.

why so expensive?
This thing works ok. It is hard to believe it reduces the amount of dust created, as dust is blowing out of the back of the saw as if that were purpose of the operation. It does cut fiber cement siding crisply and repeatedly. My 7" blade cost $6 and this costs $60, they both work equally well. Go figure!

All that's promised, I would say so far
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.
