EZARC 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.

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.

Received the multi blade pak for floor tile grout removal. The side swing design blades 2 worked really well. My wife and I used them with Dewalt 3 speed oscillating tools to remove grout in 16×16 floor tiles.The good: the swing blade design is the best of the 3.The diamond coating lasted 3 times longer than a Milwaukee diamond coated blade that was 35 bucks for one.The Bad: the straight blade worked but not near as useful for large wide grout lines 1/4 plus. Also wore out faster (diamond coating ) than swing design.The ugly: the half moon blade is too small to reach in the grout line at depth. It doesn't have enough clearance from the oscillating head to be useful. Maybe some smaller tool designs at the head other than dewalt would work.P.S. Don't bother with carbide coated blades for this type of work, purchased a pac at Walmart and they wore out very quickly.Would buy them again. Just purchased a 3 pak of swing design to finish up the 1000 plus sq ft of floor tile grout.

They do the job, thank you.

good material

They don't work very well. Struggled to put a scratch in my tile. I assume it is the case of you get what you pay for. Other diamond blades I have work significantly better.

Got these to cut through a plaster wall in a mid 50’s house during a renovation. Did a nice job with less dust than a more aggressive method. For the price, I’m very pleased.

Honestly they're really good for the price, they're a little thick for smaller grout lines, but overall a great buy for diy jobs.
