Rated 1.0 out of 5.0 by fthu Very slow to cut pavers
I just tried using this blade to cut through a 16 x 8 x 2 paver. It is a super slow process. I barely cut through the 1.5 inch depth of the paver before giving up. I think it would take forever to cut through the entire paver using this. There are lots of sparks and you really have to push to get it to do anything.

I needed to cut the end off my 20' wide concrete driveway. I started the project using two 7-1/2" masonry blades salvaged from a commercial dry saw where 7" was the lower limit. Just the right size for me, however. The two blades cut with moderate force, and finally got a 3/8" deep cut before being too small to use anymore. Although I finished the job with an Avanti diamond coated segmented blade that cut the concrete like butter, I also purchased two of these Avanti abrasive blades because I had a slight curve at each end of the cut and didn't want to use the diamond blade there. When I switched to this abrasive blade, I immediately noticed how much more effort it took to push the blade into the concrete than the other abrasive blades I had been using. Although the blade wear was less, the force on the saw was almost too much. I reduced the cut to 1/4" deep and still it felt like the blade didn't want to move through the concrete. It took more effort to cut a couple of feet of concrete to 1" deep, in 1/4" deep increments, than it took the previous day to cut the whole 20' to 3/8" deep using the other abrasive blades. Plus the saw was a whole lot hotter. I doubt that both me and the saw could have made it thru much more cutting with this blade. The blade looked good after this small project, but both me and the saw were much the worse for it.
