EZARC Oscillating Multi Tool Swing Diamond Blades, Diamond Oscillating Tool Blade, Mortar Cutting Saw Blades for Grout Removal DO57S, 3-Pack

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.

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.

Great product, excellent price

The rounded diamond blades work much much better. Not sure why but these have a hard time getting through the same stuff.

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.

I had a huge plumbing issue in my finished tiled basement and wanted to try and reuse the tiles in my bathroom to patch the main area without having to retile the entire area. I originally purchased one diamond blade from a big box store for $37 but needed more. I thought I’d try these out as an alternative and I’m so happy I did!They lasted longer and were SO much cheaper! I needed more and thought I’d try a 20 pack from a different brand on Amazon and they are definitely not as good. I can maybe get through the grout of one 13x13 tile before they dull out. I wish I would have just purchased more of these instead!

Very happy with these, I cut out 3-4 sq feet of tile and used one and a half blades, not bad for a economy brand
