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

Why did you pick this product vs others?:I was looking for blades that would cut into concrete block wall (I had to drop 6 outlets and 2 low-voltage boxes). We needed a clean cut without breaking the concrete. These worked about as well as I could have hoped. Cutting ability:They met expectations. You have to be patient with concrete and an oscillating tool. If you need to move quicker, you'll have to buy a concrete saw. This was perfect for cutting rectangles for outlets and low-voltage boxes. Cutting speed:It's a multitool blade. It's not going to cut fast....it was never supposed to. These are great blades. They do their job, and they last a proper amount of time. The price is the win here. It doesn't make sense to over-invest in blades. They do a great job at their price point.

I needed to enlarge a remodeled shower drain by one-quarter inch as the drain was installed at (a standard) 4" and the replacement drain I bought was actually 4.25". The only blade to consider cutting ceramic or porcelain are blades like these - diamond tipped. These did the job nicely with my multi-tool and left a nice sharp square that allowed me to perfectly fit my new drain.

They are just fine and not expensive.

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.

Had the regular size tile and grout blades from the same brand but project required greater depth. Cut through some structural S mortar and a little brick. Very slow on the brick would recommend and simple diamond blade angle grinder or circular saw with stone blade. For grout and fine finish work there is nothing better. Price is fair but not really a deal. Worth the price of a consumable tool head. Would recommend and buy again if needed.

I found the diamonds on the cutting edge to be easily worn off. I've used this brand before and have had good results, especially for the price. Considering you get 3 blades for less than half of the name brand, it might be worthwhile to use these and just throw them away once the cutting action is gone.

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.

I initially had a bad experience with these blades, but the service team reached out proactively and wanted not only to make it right, but find out WHY i had a hard time.That says alot and shows me that I just had bad luck. I would trust this brand again for replacements.
