Universal Fit 3-1/8" Carbide Semicircle Oscillating Saw Blade is rated 3.8 out of 5 by 6.
Rated 5 out of 5 by from Grout killer Bought this to replace a single tile in the bedroom. Before I could get to that a bathroom floor at work with a soaked subfloor under tile and cement wonder board that had to be taken out. This blade easily ripped through the grout and cement giving me an area to get the rest of it up out.

Rated 5 out of 5 by from Works Great! Not cheap but worth the money. A couple of these blades turned a four or five hour grout removal job into a thirty minute cake walk. I would also recommend the carbide pointed rasp for corners and tight areas.

Rated 4 out of 5 by from Works well, blades wear quickly These blades work as described for grout removal. Blade swap is pretty easy once you figure out how it works. Required a couple hours and 2 1/2 blades to remove 1/4" grout lines for approx. 70 sq ft.

Rated 2 out of 5 by from Great until the carbide wears off Bought this yesterday to remove 1/8 grout in a small shower. Worked really great for 1/2 of one shower wall. From then on, I had to rotate the blade several times as the Carbide started to wear off. By the time I finished (just one wall) all the carbide had worn off (it was also leaving black metallic marks in the grout line. I wish this had been more durable. I thought that it would have got me through two to three walls before needing replacing.

Rated 2 out of 5 by from Poor performance I bought this today for a regrout job I am doing. It only lasted for 20 feet of 1/8 " groute line and was worn out.
