Best 7 Inch Diamond Saw Blades of 2025

"I had to make a cut in the concrete around my pool to access a pipe. This blade cut like butter even with my old and weak circular saw. I used the hose to keep water on the cutting area to minimize dust and heat. Worked great!"

"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 no need to rent special equipment. It arrived, but wasn't the same item in the photo. I was concerned because other reviews said it might not last. Ignoring the warnings, I used it anyway and it worked great! Made about 20 cuts with no issues. Great blade for the price!"

"Installed this on my M18 Fuel cordless circular to cut crack control grooves in a concrete slab. It cut just as easily as cutting plywood. No water was used, but I’d recommend wearing a mask to avoid breathing the dust. Blade worked better than expected!"

"I bought this DEWALT diamond blade for a DIY project, and I was incredibly impressed with its speed and durability. It cut through brick and concrete like butter, and it stayed sharp even after tough jobs."

"I've been tiling my 12x32 screened porch and decided to try this blade because of its positive reviews. Even at this price, I thought it was worth it even if it lasted only half as long as pricier ones. Amazingly, I'm nearly done cutting all my tiles, and the blade is still going strong. It's a bit worn now, but I consider this a great buy and would definitely get another QEP blade."

"I used this blade for installing about 250 square feet of porcelain tiles in a bathroom remodel, and it performed exceptionally well. The chipping was nearly undetectable, which was a huge improvement over the original blade that came with my QEP wet saw. I'm very satisfied with the results!"

"I ordered this blade as a replacement for a dull mesh blade. After trying it out, I found it cuts like a champ but left some edges a bit chippy on the back end. I was working with Bedrosians Sahara tile, which is quite solid, and I had to stop after a couple of cuts due to the chipping. I think I'll try the BOSCH DB743S continuous blade next to see if there's a noticeable difference."

"I'm cutting up a quartz slab for my bathroom remodel, and this blade is much better than my previous one. Clean, straight cuts with little resistance—I'm really happy and highly recommend it!"

"This blade easily cut through some 1/2” granite with my angle grinder. I used a spray bottle for wet cutting, and it worked perfectly!"

"Unfortunately, this blade didn't meet my expectations. While it cuts quickly, it left tons of scuff marks on my work and chipped significantly on the materials I tried."

"I truly can't believe how good these blades are! While remodeling a bathroom, I encountered major water damage on the original oak subfloor. My multitool carbide blade struggled with the hardened steel cut nails, leading to frustration. After switching to these blades, I was amazed at how quickly they cut through nails and the oak, and they still have plenty of life left! Highly recommended!"

"For my small bathroom remodel, I needed to cut about 20 porcelain tiles. These blades exceeded my expectations with fast, clean cuts and no chipping. The price was very reasonable, and I would definitely buy them again. Surprisingly, I even used the blade to trim the edges of tiles, and it worked perfectly!"

"I found that these blades cut porcelain tiles with ease and provided a decent finish, though there were a few chips; I suspect that was due to my handling rather than the blade itself. I would definitely recommend them for anyone working with porcelain, as they last a long time!"

"I found the QEP 6-7001Q blade to be incredible! It cuts through different types of quartz like a dream. The narrower kerf really helps save material and power. I've actually ordered three more blades because I'm so impressed!"
