4 Pcs Oscillating Multi Tool Diamond Blades for Grout Removal Oscillating Tool Flush Cutting Tile Masonry Diamond Blades Compatible with Bosch Dremel Fein Makita Milwaukee Ridgid Ryobi XG3304D

Worked very well..Good product.

I was a bit messy with tile and allowed thinset to build up where the tile leveling system clips were. I used this to cut the thinset out from between the tiles before grouting. These cut through the plastic leveling clips as well. For less than the cost of one grout blade at the local hardware store I got four blades. Over 200 sq ft of tile I used one blade until it was completely used up. Then I used another blade for the remaining ~50 sq ft of grout lines. Great value.

Picked up these blades for my Ryobi multi-tool. Fit was perfect. The blades are described as "diamond", but I'm not sure that's the real situation. Nevertheless, used these to cut out some tile and grout during a bathroom rehab job. They work, but slowly. I expected a more aggressive cut based on the videos, but that didn't happen. However, with a little patience, the tools worked fine. I did see more wear on the blades than should have existed for "diamond" blades, given the limited use of them, but they did work. For the price, they were worth the purchase.

I didn’t want to buy or rent an angle grinder that I don’t have to route a 10’ crack in a concrete slab on grade driveway in preparation to seal, so thought I’d give these finger carbide blades a shot since I already own a Dewalt 20v cordless oscillating tool. The reviews were pretty positive regarding grout removal and the video of the guy grinding a brick was impressive, but I was curious how they would stand up to prepping a concrete crack. In short, I was impressed! I used one blade to prep a 10’ long crack that went from about a 1/4 inch to 3/8 inch in width. Not only did the blade dress the edges of the crack nicely making them uniform for the backer rod and sealant installation, I was also able to cut down deeper in the slab where necessary for the proper depth of my repair. I’ve posted a before and after photo of one section of the prep. You can see how nicely the finger blade prepped the edges and made a more uniform crack to seal. The carbide blade showed some buildup from the grinding but I couldn’t see where any of the carbide particles wore off. Incredible. In closing, using one XXGO carbide blade that ran less than five bucks I was able to prep this crack and avoid buying or renting an angle grinder. I love my Dewalt oscillating tool and now I have another application that truly makes it a multi-tool!

Good for de-grouting or even just removing the cruddy surface portion of grout lines. Take out enough old grout to provide a good surface for an epoxy grout to secure to and enjoy the wonders of modern building technology. Epoxies still require cleaning, but it's easier and they don't stain like old grouts. These blades will, of course, remove failing/cracking grout between tiles for more thorough work.

I went with lower price item .You get what you pay for in this case.I used one the blades and it did the job .Cutting tile and a little concrete ,It’s not a long lasting product .I got one use out of one blade .Good for small jobs .

Worked very well for leveling concrete next to hot water heating pipes

These do not cut mortar as stated. They might be fine for PVC or Wood.

Muy prácticos

Funcionan bien

Las hojas semicirculares están muy chicas, lo que limita mucho la profundidad de los cortes, o bien me obliga a pegar mucho la máquina a los muros, o a la superficie de corte.

conforme au descriptif. bonne qualité

The saw blade did the job (mortar removal under removed old tiles to prep the area for tile replacement). I cannot speak to longevity of these blades (I used one of the blades for about 30 min) or their performance on tougher jobs, but for me it was a great value for the price.
