Product Overview

Diablo 's premium HardieBlade 12 in. x 8-Tooth PCD Fiber Cement Saw Blade is the only saw blade recommended by James Hardie. Designed with Polycrystalline Diamond (PCD) tipped teeth, the blade is specially formulated to combat the abrasive properties of fiber cement for exceptionally long cutting life, lasting up to 60 times longer than regular carbide. Super-thin kerf laser-cut blade allows for fast, clean, super thin cuts that reduce reparable dust generation by up to 50% for a cleaner, safer work place. Spark eroded Triple Chip Grid (TCG)-Tooth geometry is specially designed and created using spark erosion dramatically increases the cutting life of the blade in all fiber cement products. Laser-cut stabilizer vents absorb noise and reduce vibration for a cleaner cut and longer life.

  • Diablo fiber cement blades generate up to 50% less reparable dust
  • Durable TiCo high-density carbide teeth for razor-sharp cuts and longer blade life
  • Permashield permanent coating prevents gumming and corrosion

  • Covered by limited lifetime warranty

Answer: 
Yes. Although rather than a Skil saw I used a Bosch 7 1/4" 12 amp circular saw and it worked perfectly. It went through the Hardie Backer 500 material as easy as a 3/4" piece of plywood. I tried other blades before using the Diablo and they were all ruined after doing small cuts. Once I installed the Diablo blade I did a complete shower installation and at the end the blade was cutting just as well as it Read More

Sounds like your doing everything right, I was going to warn you about the dust, but if your outside and using a mask it's no problem. Read Less

Answer: 
Hold up? Not only will it hold up, it is THE ONLY blade that will hold up. You will ruin the best carbide blade in one or two passes. I did my entire project with this one blade, and a Hitachi jig saw blade made for fiber cement, to finish inside cuts started with the circular saw. I used this blade with my (7-1/4") Milwaukee brushless saw. The Milwaukee brushless tools are absolutely phenomenal in their Read More
Hold up? Not only will it hold up, it is THE ONLY blade that will hold up. You will ruin the best carbide blade in one or two passes. I did my entire project with this one blade, and a Hitachi jig saw blade made for fiber cement, to finish inside cuts started with the circular saw. I used this blade with my (7-1/4") Milwaukee brushless saw. The Milwaukee brushless tools are absolutely phenomenal in their power and battery life.
You are on the right track with dust mitigation. This blade does reduce somewhat the dust produced, but you still definitely have to deal with it. I tried using a mask, but with glasses, it just wasn't working. You must have eye protection however. The blade tends to spit tiny little bits all over the place. I made sure my cutting took into account the wind direction, and I also used a fan to keep it going in the right direction. For a few long, rip cuts, I even resorted to controlling my breathing. You can't make a 12 foot cut without stopping to reposition yourself, so I would hold my breath while I cut where I was standing, breathed when I stopped to reposition, and so on. If you were doing this for a living, you would have to have the dust extraction system even outdoors.
Since this saw blade is directly related to fiber cement board installation, I hope the moderators will allow me this one other recommendation. Do whatever you have to, to get a SIDING coil nail gun. Forget the cost. Trust me, you will thank yourself a 1000 times over. I got the Hitachi and believe me, it was worth its weight in gold. It was SO much easier, mostly because it allows one-handed nailing while holding the siding with the other hand, not to mention being able to place a nail at arms length. I did have some help, but I did probably 90% of the siding by myself. Read Less

Answer: 
This blade is not recommended for use in Wonderboard because it is cement board versus fiber cement. That being said, the blade will cut Wonderboard; however it will not last as long as it would cutting Hardie/fiber cement. We recommend an actual diamond blade when cutting cement board.

Rated 4.7 out of 5 by 42 reviewers.
Rated 4.0 out of 5.0 by Blade for cutting cement The blade cut through cinder block and patio block very nicely. However, it didn't last as long as I had expected or hoped, especially for $55. I was careful not to force it and to let it cool every 15-20 seconds. Even so it did a medium sized job, but died at the end. September 14, 2016
Rated 5.0 out of 5.0 by Hardie Blade Have ripped many Hardie board pieces of aiding and the blade is holding up very well. September 6, 2016
Rated 5.0 out of 5.0 by The best Diablo blade made my job easier. Great to work with. I loved it could not ask for more. September 12, 2016
Rated 5.0 out of 5.0 by Everything it is said to be. You wouldn't think a blade with just four (4) or six (^) teeth would be any good, but this one is. It not only cuts the Hardie/Fiber Fiber Board with ease but it has very little heat build up. Makes a very nice cut. August 23, 2016
Rated 5.0 out of 5.0 by Hardie BACKERBOARD blade Product did exactly what was claimed. We used it to cut 1/4-inch Hardie board. Minimum of waste and dust. Blade still holding up well. July 12, 2016
Rated 5.0 out of 5.0 by Diablo Hardy Board 7 1/4" blade This blade cuts Hardy Board like a sharp knife through butter! June 28, 2016
Rated 5.0 out of 5.0 by The only blade to use on cement board!! This was the first time I had worked with Hardie Backer 500 cement board and I was having a terrible time trying to make cuts. I made a trip to Home Depot to see if I could find anything to make the job easier and just happened to walk past the display of 7 1/4" circular saw blades when I saw a Diablo blade that was designed for the exact product I was working with. It was a little expensive, but I was tired of burning up other blades that didn't work at all. Man, was I surprised when I made my first cut, this blade goes through Hardie Backer 500 like butter. I did a complete shower remodel and it's still working as good as it did when I started. If your working with cement board, do yourself a favor and pick up one of these blades, you'll be glade you did! March 22, 2016
Rated 5.0 out of 5.0 by Concrete blade This blade lasted the entire hardie siding job. I cut numerous pieces of hardie all week long and the blade stayed sharp the entire job. I'm very pleased with the product January 1, 2015
