3Pack 4-1/2-Inch 60-Grit Diamond Compact Circular Saw Blade with 3/8-Inch Arbor, for Cutting Ceramic Tile, Stone Tile, Backer Board and Cement

worked perfectly for me, cut through some solid surface counters like butter!

I used these to make two ~30 inch cuts to trim a quartz countertop to the correct size. I used these in a little battery powered DeWalt circular saw. I only needed one blade and it seemed to last all the way through both cuts. Looks like it still has some good life in it. The cut was clean with no chips. I didn't use water. I just cut slow and didn't push too hard. It probably took ~5mins for each 30 inch cut.The hole in the middle was just a little bit too small to fit on my dewalt saw. I used a rat tail file to very slightly open the hole and smashed it onto the saw. Considering I only needed to use this once, and never again, that is acceptable.

These blades are very well made, the steel with embedded diamond grains is very durable. In order to maximize their longevity it’s crucial to do the cutting with running water/lubricant. I wet cut 16x32 5/16 tile and these blades cut through like butter. No slow down at all with my Dewalt 4 1/2 saw. With a 6ah battery I can easily get 10ft of cut. There is minor edge tearing, but I was cutting fine porcelain tile. I used painters tape to keep the cutting edge nice and clean. Still on my first blade and no signs of dulling after 30ft of cutting. Considering the price per blade this is a no brainer purchase. Highly, highly recommended!!

Works as expected on hardyboard

I used it to trim concrete walkway stones that i poured myself.It was a lot easier to trim them after, rather than trying o shape them in the process.Lot of concrete dust of course when using it, so wear a mask.Just have to go slow, and steady to get nice smooth cuts.I used it in my cordless "Yellow" saw, and didn't phase it.

These are some beast saw blades. I needed to cut a two inch wide, 18 inch long, and 1.5 inch deep channel in my HVAC closet to help prevent any back ups in the condensation line drain from flowing back into my house. These were the correct size for my compact circular saw I had just purchased. I was able make the two outside cuts at 1/2 inch depth first then all the way down to 1.5 inch on the second pass. From there I just continued to make several cuts along the 18 inch length then take a hammer and chisel to break out the narrow strips left over. I was able to make about 3/4 of the total cuts on the first blade and only changed to a new one when I could tell the first one was struggling to cut and my saw was getting how from the extra strain.

I used the one of the blades to modify a red brick and mortar wall around a carport. Theblade performed very well, made a nice clean cut and stood up to the task. The 3-pack is agreat value. Three big box stores had zero 4.5" blades with a 3/8" arbor, which led me to theseblades on Amazon. Perfect result.

Only used One blade for all my cuts so far. that includes shower enclosure (20 cuts approx. 41 Linear ft. Bathroom floor 4 cuts approx. 20 Linear ft. The blade seems pretty good and I will use a new blade on the tile when I have to make cuts (shower, handheld, valve etc) and will update when finished. So far happy with the quality, performance and price.
