Diamond Oscillating Blade, Flush Cutting Oscillating Multi Tool Saw Blades for Grout Removal, Cleaning Mortar DO34F, 3-Pack

I bought these months ago for another project. I was in a time crunch and they did not arrive in time so I used every other brand available locally. Milwaukee, Diablo, Dewalt, etc. These got the job done but I burned through a lot of them on a relatively small job. Fast forward to a week ago. I had another failed shower repair job. Hands down these are the best blades for cutting through grout, cement board, thinset and some tile. They are sharp enough to make the initial cut and stay on track without bouncing around. They held up through a much more material than the other brands. To the point I was getting quite aggressive and basically abusing the blades. Excellent durability, remained sharp and therefore safe and accurate. If the blade is not sharp enough it will bounce around and scar the adjacent tile...making the job bigger, more time consuming and more expensive. And they are much less expensive than the box store brands. I have ordered more just to keep in my tiling tool kit. Quality, durability, and value all top notch. I try out EzArc's other oscillating blades with hopes they are as good as these.

Works better than it should. Like butter through grout!

They are just fine and not expensive.

Good buy

Ok

Was having some despair when after two days of work I had struggled to cut out 1/3 of the ceiling opening for a new attic ladder and melted through over $50 of blades. When I finally got a piece out and realized it was rock lath (plaster over a cement board) it made sense when even hardened cutting blades were melting in moments. I didn't feel comfortable taking a diamond cutting wheel on a rotary cutter to my ceiling, and over my head, so I tried these on the recommendation of the normal oscillating blade's quality from a popular review source and order three packs of them - hoping they would work but expecting to still need a bunch. Turns out one blade finished the removal of the ceiling in a fraction of the time and effort as I had spent already. It's still a slow, terrible, awful, messy, nightmare of a process to cut through rock lath since you're just grinding it into fine dust. These worked though and left a relatively clean and stable edge (rock lath usually winds up ragged and crumbling with standard tools). Still make sure you put plastic up to contain all the fine dust and wear protective equipment. Hopefully these work as well on my grout issues when I get to that and will keep them on hand for anytime I need to cut into the rock lath walls in the future.

Blades did not perform as expected. Would not cut through clay brick. The cutting surface burned up despite keeping the material wet.

The Diamond oscillating blades work ok, but wear out too easily when using to clean grout prior to regrouting.
