15x Longer LifeGround, Hardened Body for Smooth, Accurate Cuts
In order to perform well, a saw blade needs to start out flat and stay true throughout its life. Irwin Marathon blades, like this 10-inch fiber cement blade, feature well-balanced bodies that are laser cut then ground and hardened to help you achieve cuts that are smooth and accurate. This leads to more efficient work flow and cleaner, more precise end products.

Polycrystalline Diamond-Tipped Teeth for Durability
Overall performance often comes down to the configuration and dependability of a blade's teeth, and this long-lasting Polycrystalline Diamond Fiber Cement Blade is no exception. A low tooth count and large gullets are suited to the specific demands of working with fiber cement products. Moreover, polycrystalline diamond (PCD) tips provide extended tooth life, allowing this Marathon blade to last up to 15 times longer than a standard carbide fiber cement blade.

In addition to offering overall precision, the blade's laser-cut body also allows for a stronger tooth bond, which improves durability. This blade can handle cutting up to 9,000 feet of fiber cement before it needs to be replaced, which means less downtime for blade changes. And it can cut up to five stacks of fiber cement at a time.

Reduced Dust Production for Improved Safety
The 10-Inch PCD Fiber Cement Blade's notched design allows it to produce less dust than a similar continuous-rim blade. Coupled with the blade's thin-kerf, six-tooth configuration and its PCD tips--which also contribute to its reduced dust production--this notched design helps keep your work site cleaner and safer.

Style Name: Metal CuttingSize: 7-1/4" 68T Verified Purchase
Bought mine to cut steel roofing. Stacked 12 sheets of ribbed 28 ga. by 3' wide steel and cut all 12 sheets in one pass in matter of seconds and NO sparks! Used sabre saws and nibblers in past. No comparison for straight lines and speed. Have also been using it to cut angle iron and bar stock. Many times faster and cleaner than my 14" cutoff saw that uses an abrasive disc. Not having a shower of sparks and the accompanying fire hazard is a huge benefit. After several roofing jobs and many misc. cuts, it is still as sharp as new. If it ever does get dull, any saw shop can sharpen it for around $10 or less. The info says for thin steel but I consistantly cut up to 1" by 6" solid steel flat bar stock with no effort whatsoever. The 48 tooth blade doesn't cut thick steel any faster than this 68 tooth and the 48 tooth will not work as well on thin sheet steel. As a matter of fact, the 48 tooth is dangerous on thin stock as it will over-feed and grab. If you are cutting various different thickness of steel, buy this one, and skip purchasing the 48 tooth. This 68 tooth blade is all you will ever need. For best results give it a shot of WD-40 on both sides of body in between cuts. A little bit of lubrication makes cuts effortless. Yor will find yourself actually holding back on it as it virtually self-feeds into the material. After one job this blade paid for itself many times over. Will never be without one again. Only regret is not buying one years ago.

I've bought a lot of 10 inch blades over the last 40 years, DeWalt, Craftsman, Freud, Infinity, you name it, I've used it. This blade has become my favorite. Clean cuts, well balanced, not that expensive, and has held up well for sharpness the last couple of months under extreme use. I'll continue buying Irwin Marples in the future until someone can show me a better deal.

After burning out my Leitz combo blade trying to rip 6/4 hard maple, I picked up both the Irwin Marples 24T rip blade and the very similar Diablo blade. Both were good value for money and both chewed through maple like the proverbial knife through butter. I stuck with the Marples because it delivered a cleaner edge (though not quite a glue line rip) and potentially longer life span because of the super-sized carbide teeth. Seriously, this blade has quite the set of choppers. Irwin has delivered a professional-quality blade at a DIY price. Kudos to them. Then again, they really owe us one for outsourcing the Marples bench chisels to China.

I used this blade to cut 3 large holes in a metal building (R panel) to install 3 28,000 BTU through-the-wall air conditioning units.

Cutting was smooth and consistent with minimal vibration. It made the job quick and easy. Highly recommended.

The new Irwin Italian-made blades match Freud feature-for-feature at a substantially lower price.

I finally decided to stop compromising with a combination blade in my table saw. This thin kerf rip blade requires noticeably less power to rip thick hardwood stock. There is no burning and the sawn edge is smooth enough to go straight to glue-up.

Note that i am comparing this blade to the one that came with the Makita saw . No comparison, this blade leaves a much heavier burr on the cut piece. A burr that compares to the Makita blade after we had cut maybe five hundred pieces. This blade started off with that so I am a little leery as to how long this will last us. We cut inch and a half .095 wall DOM tubing, a lot of it. Each day a batch of 60 parts are cut. That's 300 plus cuts a week. The last blade lasted 2 months, and the only reason it gave up the ghost is a piece of angle iron I was cutting got loose and the blade flung it a bit and chipped several teeth. Long story short, I am ordering a new Makita blade soon. This one will do the job for now but I doubt it's ability to last. I will update in a few weeks... if it lasts. I have no problem eating crow if it comes to that. Lol.

UPDATE: NO Crow for me. Sadly, it looks like i was right. This blade is not going to make it. I already ordered a new makita. Just two weeks into it and it is already noisier and cutting slower and with more sparks than the makita ever did. I will keep the Irwin as a back up blade but i hope i never have to use it again. It leaves a huge burr on the workpiece that must be sanded off with the belt sander. Not acceptable at all. This blade might be ok if you are a hobbyist, but for a production shop like mine.. no way. I don't need extra steps added to my schedule. and that large burr is an extra step. Not to mention the horrendous noise, far more than the makita, and when you can get the makita for 99 bucks and free shipping the small savings on the irwin simply does not make any sense, and the makita will outlast this Irwin two to one.

I bought the saw blade for use with my Dewalt cordless saw. My hope was that it would work as well as Dewalt's equivalent product, but at almost half the price. So far, I have used it for cutting paneling sheets for the walls of my new man cave. It cut perfectly! Highly recommended!

Finished painting and wanted to put a clear acrylic sheet next to the door to keep the dogs from scratching the wall. Tried cutting the acrylic sheet with a knife and failed miserably. Next attempt was with this blade. Worked great and left a smooth edge.
