Customer Reviews

Hardiblade is an excellant product
I used a Hardiblade in my Radial Arm saw and another in my circular saw while installing Hardiplank siding on my daughters house. The cuts were straight and clean. This was the first time I have installed cement siding and I was a little apprehensive about cutting and nailing the siding. The blades cut much easier and with much less chipout and dust than the carbide blade I tried at first.

I would reccommend this blade for any cutting of cement siding.

Excellent Blade
The Hitachi PCD blade surpassed all my expectations. It made crisp, clean cuts that were indistinguishable from the factory edges. The cost of the blade was insignificant compared to the time and money it saved me from changing carbide-tipped blades.

Does the Job
I started my siding job with a Piranha carbide blade in my circular saw because the Hardiblade I ordered had not shown up.

After one afternoon of work I could see the blade was wearing out and was sparking on the cement board, indicating the carbide teeth were burning up.

When I got the Hardiblade I put it on and continued work. Noticed right away that it slings less dust and it lasts for a loooong time. I made quite a few long rips with it and it cut very easily.

Do I think these blades are worth the very high price? Nope, they can't cost that much to manufacture.

Do I regret buying it instead of trying to use carbide blades for the whole job? Nope.

It's a good blade.
