The media could not be loaded. These blades cut through the concrete like butter. Was a bit hesitant to buy because of how cheap they were. I'm thankful now that I had bought them. Will be ordering several more for my projects.

These are perfectly good diamond blades and I would purchase them again. A majority of diamond blades that I have used on an angle grinder seem to leave edges that are a chipped, ones I wouldn’t want out in the open and these are no different. Usually it’s not an issue because I only use my grinder to make rough cuts that will be covered up. I do like the three blade kit that allows me to use the appropriate blade for the task.

For my job I use 4 ½” diamond blades about once a week. These blades initially looked like an “economy” or “bargain” 3-pack, but I thought I'd give them a try anyway. In the past I have used only more expensive name-brand blades. I use them to cut concrete, granite, tile, and cement board siding. For the concrete and granite they are only used for rough cuts, but tile and cement board require clean straight lines. I found that these Sali blades were no different than the name-brand blades that I have used for years. I am pleasantly surprised.

These Diamond blades are just as good and last easily as long as the name brand versions.I have been working on a flagstone patio and they cut the stone very nicely. It is definitely a good idea to use them wet vs. dry since they will last much longer - which is true for all diamond blades in my experience. So far I am still on my first blade and it is doing a great job.For the money, they are a tremendous value.

This Product works well and cutting out mortar joints. It did waste faster than the others I've had but it did the job.

This review is for the Sali 3 piece Angle Grinder Diamond Blade Kit.Overall: 5 StarsReally nice set of grinder blades. They all fit my Porter-Cable 20V cordless grinder perfectly and are well balanced. I'm very impressed with the quality of these blades and how well they perform. I rarely cut ceramic tile or other similar materials but I think these blades are going to do the job admirably. I also think that the price is right for this blade and I'll be purchasing other blades like this in the future. I'll update this review after I get some use from the blades.

The first blade I used was the one with the largest spaces between the teeth - it did the best job at cutting the concrete. I cut around 20 linear feet of concrete before it really started to have a hard time. I used it for an additional 5’-8’ and was starting to throw sparks when I finally went to the second blade which was the next one with smaller spaces between the teeth ~ (Which I was not impressed by. It took way too long to cut and make any progress.) Looking at the blade afterwards you can see where the diamond cutting bits totally wore off. I guess for $10 for three blades they are ok, but I have two Spyder blades that I paid a couple dollars more for that are still fine, (I’ve had them for a while and have used on several projects). I’m not a fan of these blades for larger projects, maybe something quick and small, but that’s about it.

So, I took one of the blades and, using a paver which is very dense concrete, cut a corner out of the paver. The blade seemed to work fine and easily cut the paver. Of course, this being a 4 1/2 inch blade it will only cut about 1 1/4 of an inch deep using a right angle grinder, but that is expected. Otherwise the blades, at least the one I checked, worked fine and I think the price is right. I rarely use one of these blades but didn't have any so it will be nice that I have some in my grinder bag when called for.
