DEWALT Diamond Blade for Block and Brick, Dry/Wet Cutting, Continuous Rim, 7-Inch (DW4712)

This diamond blade is a "wet" cutting blade, not a "Dry/Wet Cutting" one as in the title. Not a problem for me as I use water anyway to keep down the dust. Works well with a 7" angle grinder on concrete. It cut quickly and cleanly for me.

I originally ordered this to cut a corner out of my driveway where we experienced some settling and cracking. The slab ended up being 3-4" thick, with a couple pieces of 1/2" rebar. I took it slowly and had a steady flow of water flowing onto the blade and it did a great job of cutting. I took 15-20 minutes to cut this section out of my driveway. I was very nervous about the rebar but it turned out to not be an issue. I just took it slowly.After that project, I wasn't sure I'd use the blade again, but I don't throw tools away unless they're actually broken and unrepairable. So, into the garage this went. It fell on the floor and sat in a spot by the door that got wet over and over. I found it with one side covered in rust and put it away again.This week I was cutting a slab of granite and was using a tile saw blade meant for granite and natural stone tile. Then I remembered this thing. Though marketed for masonry, I figured I'd give it a shot. The diamond pattern is more aggressive with a thicker kerf. I tested on a scrap piece first and It blew me away how well it cut. The rust was a complete non-issue.I cut another ~20 linear feet of granite and it had plenty of life left. Way better than the tile saw blade. Again, water was mandatory so I could see what I was doing and keep the mess and dust down.I found that the absolute best way to do this alone was to set my workpiece up on a slight angle, so that I was sawing "downhill" and make one very shallow pass with a hose pouring water onto the slab. Then for the next cut, I put the water stream into the kerf behind the saw and it flowed down to the cut to cool and lubricate. I made a total of three progressively deeper passes then the fourth pass finished the cut. I was left with a beautiful edge, ready for polishing.10/10 experience and fantastic value.I did not have any issues with the brass insert.

This blade is awesome,cuts threw bricks like a hot knife threw butter.

I needed a blade to trim a few pavers and a retaining wall cap for a patio I was finishing up. This blade was my solution, good price and I don’t need to rent any special equipment. I purchased to use with my circular saw. It arrive but was not the same item in the photo. The hole was diamond shaped and had a ring adapter in it. I was concerned as the other reviews said it won’t stay or won’t last. The back of the packaging did have a warning in size 3 font not to use with circular saw. Of course, I did what any man would do, ignored all these messages. It worked great! Made about 20 cuts with no issues. I used a hose and wet the paver I was about to cut to minimize dust. I also used a few extra pavers to surround the paver I was cutting to hold it in place. Great blade for the price! By the way, they sell diamond to round hole adopters on amazon.

Cut my own 1.25” granite with tape and water. Worked great for my rough project.

Cuts great. Seems to be a solid blade. Throws a lot of shavings however thats not the blades fault.

Though not advertised as such, I found it to be very effective at cutting quartz countertop (not the natural quartz stone). I used it to cut a 3/4" side splash to length. I taped the cut line to minimize tear-out and the cut was very clean. I cut slowly and without any water. The only problem was the cutting guide for my circular saw wasn't great and because my saw dipped (angled) a little, the other side had some jagged areas that I needed to file down. The kerf is about 2.8mm and there are probably better and thinner blades for this purpose but this was a great price for a one time use

Works great. Cuts stone ledger panels with ease. I would purchase again when I need to replace the one I have.
