IRWIN 15702ZR 7-1/4" 6T Fiber Cement Irwin Classic

The blade completed my project with ease and at half the cost of a competing brand how can I not be pleased!

January 8, 2024 update.Well, dang. As you can read in my original post, I was pleased. BUT, now not as much. As I continued to-use the first blade it started to wander. I began began using a 6foot level as a guide instead of freestyle and found the blade has now lost 4 of six tips. This after maybe 100 linear feet of cuts. So I swapped out to the second blade and wow, back to speedy straight cuts.TAKEAWAY? consider it a disposable for little jobs. I will buy an expensive version next and report back!Original review:I've been using a masonry blade on my skilsaw to cut 5/16" Hardie 4x8 sheet siding panels. That's because I already had one and all the cement board blades seemed too pricey. I saw the price drop on these, but boy! So many bad reviews. So I bought two figuring I could always send them back. Plus I could compare the wear on the first one to see how it is holding up.The verdict after 24 linear feet of cuts?THEY ARE GREAT!They produce much less dust (you still need a good n95 mask and good ventilation) and cut clean, straight and fast. I'm really happy to be relieved of what was a nasty chore. There is NO visible wear so far on the tips. Highly recommend. Wish I had not been such a cheapskate before. Can't expect them to last forever, so I will return for more. And maybe get a 10" for the radial arm cutting smaller pieces. I expect I will be just as happy cutting Hardie tile backer.For what it's worth: I'm not an AI robot posting fake reviews. Nor was I asked specifically, nor incentivized in any manner, to post a review. I do not expect anything but to get what I paid for. I think this time, I did even better.

Absolute rubbish product. Bought this product to cut blue board to size. Failed on the second cut. All the teeth broke off.

Worked like a champ.

Used this blade to cut cement board siding.
