XXGO4 Pcs Oscillating Multi Tool Diamond Segment Swing Semi Circle Grit Grout Saw Blades XG4002D

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.

These are perfect for when you’ve got large sanding jobs and 60 grit is taking too long. I’ve used them to restore 12 foot wide 4 foot high signs with over 40 ft.² of deteriorated background. They last forever on wood. I’ve used the same one for 8 years. I bought this pack because that one had a little dimple in it that was making uneven streaks, which was actually helpful because it really dug in fast, but I bought these four to get some with the more random patterns.

Used to cut ceramic wall tiles. Worked pretty well but did not last as long as I thought they should. Had to cut slow and replace blade after maybe 15 tiles of 6x12 inches. Fits standard oscillating saw with that design. Mine was jorgenson.

I bought these to remove a bad grout job we inherited when we bought our vacation home. It made quick work of the removal leaving clean grout lines these won’t last long for a contractor but if you’re looking for a diy set these are worth the fair price

I was expecting to grind right through old grout, but the bottom edge didn't seem to last very long on the circular attachment. Maybe the straight edge attachment will work better. It did fit my Craftsman multitool no problem.

Durable cuts through most materials

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!

Absolute junk. The longer blade lasts for about 20" of grout before the 'diamond' completely wears away. The shorter blade is not long enough for a Dewalt, the Dewalt tool hits the work before the blade does.
