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

I purchased these for a job where we wanted to make multiple detail cuts in 1950's plaster walls.We loaded them into the multi-tools and worked a full shift cutting plaster. The work is slower than using diamond blades in a grinder. The grinder solution makes a huge, huge mess. The multi-tool makes better cuts and you can keep up with the plaster dust with a shop vac. The blades lasted a whole shift and will go back to work tomorrow. I will repurchase them and keep them on hand. They are way better for grout and plaster than the store-bought ones.

I have remodeled and replaced a lot of tile, and old worn-out grout over the years and the one thing I always hated was removing old grout. It is labor intensive. I started using an oscilating tool which saved a ton of work but the blades wore out quickly. Last weekend I bought a single "grout blade" for $50. Within an hour and with only 10% of the grout in a shower removed that blade was toast. I decided to give these a try. 3 blades for $15. OMG, these blades were cutting through the grout like it was sand. What had previously taken me 10 minutes to remove was now taking 30 seconds to a minute. I finished the entire shower in a couple of hours. Since there were three blades I changed them every 30 seconds or so, so they never got to hot. All three blades are still working like they are brand new!Additionally, they are half the thickness of other grout blades, this is a huge advantage. I was able to cut through the center of the grout without hitting the tiles (and thus damaging them) on either side. Once deep enough into the grout I could then use the sides of the blades to basically sand the grout on either side. I was removing all the grout and didn't damage a single tile.I highly recommend these blades for grout removal. I just regrouted my whole shower in a tenth the time it used to take me, and the results were much better: I got ALL the old grout out and didnt scratch or chip a single tile in the process.Swap the blades out frequently so they don't get to hot and they should last at least 10 times longer than much more expensive blades.

I used these blades to finish my counter tile and float saw cuts at the edges near the walls. Cheap and did the job but they wear out rather quickly. I used only two blades for the cuts I needed to demo a large tiled kitchen and wet bar. Worth the purchase.👍

Perfect for cleaning out grout lines after laying down tile. Took two packs to complete a mid-sized bath floor and shower.

I’ve used this brand for other blades and have had good results but the diamond coating on this one is rather inferior for tile cutting or heavy duty use, adequate maybe for grout removal.

Very happy. I had a small job but the diamond cutter did the job well and lasted so far. Good price- you get 3. I had bought a carbide grit cutter and it worked very poorly. Will buy again if needed.

I wasn't expecting much but this is compatible with one of my dremel tools, and this worked really well to remove some grout from my tile floor. I would certainly purchase this again, for the value and how well it worked.

Worked great for cinder block but if you catch a rock in the grouted holes it won’t cut through it. The blade will burn if you keep trying to cut the pebble but it does take a lot of abuse and the vibration sometimes will kick out the pebble. It will not burn as long as you don’t keep forcing it. Great price for its durability. Would buy again.

Used for the “verticals” while pointing a wall. Work speed was tripled using these and other cement cutting tools. I now can enjoy my summer.

Las use para remover piso, no remueve mucho pero si lo suficiente para lo que yo necesitaba, me permitió hacer el trabajo más fácil y limpio.

Los materiales y la cantidad de cortadores me pareció justa

Grout removal

Heb hier al heel veel voegen mee verwijderd. Gaat als een mes door boter in mijn (500 watt) multitool en heeft een behoorlijke standtijd. Met één blad is makkelijk zo'n 10 m2 aan voegen uit tegelvloer bestaande uit 40x40cm tegels.
