4 Pcs Diamond Oscillating Multi Tool Blades for Removing Grout | Best For 1/8 Inch Grout Removal

I used these in two different applications. The traditional flat style easily removed grout from between tiles, prior to demolition - and did a great job. I used the tomahawk style to cut some HardieBacker - and although it required multiple passes - it gave a nice clean cut. Overall - no complaints - both blade styles worked like a charm!

I'm removing old grout from the floor of a tiled shower. 4'x7' with 1" tiles, so tons of grout to remove. Too big of a job for this blade, but I used an angle grinder for the vast majority. This tool attached to my Makita oscillator was perfect for getting the last inch or so against the walls where I couldn't reach with the circular blade without damaging the wall tiles. Made quick work of the grout, but the blades are thin so you have to use care not to put too much pressure on the tool while cutting. Let the tool and the blade do the work. One blade bent while i was using it, but I was able to straighten it out and continue using it. All in all I cut about 30' of grout in 1.5" increments around the perimeter of the shower. First blade dulled. Switched to the second to finish up. Still some life in the second blade. I used the rectangular blades for short runs and the arc blade for longer runs. Do not was your time on the carbide blades. Bought one at the warehouse store for twice as much as this pack of 4 and it lasted 5 minutes. good luck with your project

It worked perfectly!

Good value for the money. Good durability.

Used them to cut out some tile along the grout joints to access a shower valve. Cut through the grout and backerboard and also a marble border. The marble was slower going but they did a nice job. A grinder with a diamond wheel would have been much faster but creates clouds of dust.

Cuts fast, but wears down fast too

Wears out a little too quick. But does a good job while it lasts on plaster, soft bricks and soft cement.

Made short work of bathroom tile grout. Ate right through the old grout. Used straight and curved.

I used this to remove old thinset , grout and cement with my multitool. Great performance.

Professional quality blades; depending on job might use up quickly.

Good product. Lasted fairly well.

These were terrible. After a couple minutes of use the "diamond" blade became dull and mostly used on grout. The description says you "can" use it on tile, which I briefly tried and it didn't even make a dent. Don't waste your money on this!
