4-1/2 inch Segmented Diamond Blade, Diamond Cutting Wheel for Angle Grinder Stone Master, 4.5" Stone Blade for Cutting Concrete Granite Masonry Brick, 7/8"-20mm-5/8 Arbor (2-Pack)

I needed to take apart an outdoor fireplace, and at first, I was using a chisel—but I kept breaking bricks and struggling with the mortar. After switching to this EZARC diamond blade, the difference was night and day! It cut through the mortar effortlessly, allowing the bricks to come apart with ease. The blade is sharp, durable, and perfect for cutting through concrete, granite, and masonry. If you’re tackling a similar project, this is a must-have tool. Highly recommend!

Once I got it set up on my 4 1/2" Craftsman, it was eager to cut. Wear a face shield, don't be a fool. The depth you can cut is limited. I use it mostly for trims and nips on rock that's already stuck to the wall. Very pleased with the performance, my sense is, this first of two blades will go a long time before I need to change out. Update 12/11/25 It lasted all summer, right up to finishing "rockin' the house". I used it extensively on the last side during Sept. & Oct., doing trims away from the house. I have the entire garage to do now, and it will certainly give me a lot of service when I start that project.

Excellent blade retention. I have been using these on cement board which eats up anything else you cut it with. Great product and much cheaper then the big box stores

This product worked very well on old poured concrete. Cut like butter.

I have a portable small wet saw, I used to cut tile for our house which I tiled 25 years ago. I drug the old wet saw out and replaced the worn blade with one of these. The old blade only measured 4 1/4" . I used the new blades on 12" x 24" x 3/8" porcelain floor tile and it did the cuts. Four stars since I did get some very small chips even going at a snail's cutting pace. Almost all of those small chips will be covered by baseboard, but a few won't. I used the old blade on by angle grinder to make some cuts that I could not do on the small wet saw. No chips with the old blade and I think it was because the old blade did not have notches in it like these newer blades do. 4 stars since I got the job done.

This is our third time buying these blades and we love them. Works great for cutting stone and gets the job done quickly and cleanly. The blade holds up really well, which is why we keep coming back to buy it again. Overall, it’s reliable and works exactly as expected.

Got the job done

I purchased the EZARC diamond blades and cut really well, but I had an issue with one of the tangs breaking off with a little side pressure. The EZARC company however stands behind their product and they replaced the blade expeditiously. They have different kinds of diamond blades including a solid design with no cuts which will work better for my type of project. Thank you EZARC!

Ottimo

Met slechts 1 schijf een heel terras van schuin afgezaagde botontegels kunnen voorzien (ruim 80 meter zaagsnede, schijf nog niet op). Opmerkelijk lange levensduur. Andere schijf dus nog over voor volgend project.

Perfecto, funcionales y duraderos. Nada negativo que decir. Han funcionado a la perfeccion en distitas superficies muy duras.

Used these segmented blades to cut through concrete stucco during reno work and they performed great. Clean, fast cuts with minimal effort. I only needed one of the two blades in the pack for the entire job and it’s still going strong. Definitely outlasted and outperformed the cheaper ones I bought locally. Solid value and quality.

Perfecto
