XXGO4 Pcs Oscillating Multi Tool Diamond Blades for Grit Grout Removal XG4004D

These are what you need to cut grout and tiles. Good

Worked excellent on concrete and brick, cutting between a daisy chain of drill holes

These fit my Rigid oscillating tool perfectly. Used for floor tile grout removal. They did a fine job, but a little slow, I guess to be expected. Never done this before so when the grit wore down it was a little disappointing. Read reviews about this brand as well as better known ones and all had positive reviews and negative reviews, so wasn’t surprised. Would definitely buy again if I ever had to do grout removal again. Hopefully not tho.

The two non circular blades effectively removed Grout, but could NOT use the semi-circle blades?They are just too small?I have a Dewalt and the blade is too close to the tool to use.The Grout tool made by Dewalt is substantially larger.

Good value.

These diamond blades worked great to cut out in sanded grout in my tile back splash in my kitchen. I got them because, when trying to degrout my shower tiles I burnt through 4-5 of the multi fit dremel ones! The dremel ones are also 1/16” thick like these but I think the issue was my tiles in the shower were even closer together than that. So most of the time I wasn’t just cutting grout but also tile. What a pita! Took so long it gave me golfers elbow from the tool :( My kitchen tiles looked to be the same width from each other but it’s hard to tell when they’re grouted in. Regardless, I only had to use one of these diamond blades to cut out all the grout in my kitchen! It was so much easier than my shower. Idk if it was really the diamond blade or the tile spacing so I can’t say for sure these are better than the dremel ones, but for the cost they are worth it. I will say that there doesn’t seem to be as much diamond particles on these blades as the dremel one. But the dremel one isn’t diamond it’s carbide so it’s not quite as tough as the cutting material on these. FYI- on a linear scale, diamond is 100 times more harder than tungsten carbide. Translated to the mohs hardness scale, diamond is a 10, the hardest out there, tungsten carbide is an 8-9. One draw back is they don’t have a straight section like the dremel ones. I use the straight section of the dremel blades to get into the corners of the horizontal grout lines.

Wasn't sure going in to it but now they are the attachments I look for before the others!

I had a project where I had to remove LOTS of grout in a tile wall. I figured for the price of these blades, what the heck. I got the 4 pack for what 1 blade costs at Home depot or Lowes and those don't last that long. I would just use them and toss them. I was suprised at how well they held up. I purchased a second pack figuring I would need them but, to my suprise, I only used 3 of the origional pack. I only changed them because they slowed down some at their end of their life. One warning is they are NOT able to cut ceramic or porclean tiles. I have NOT tried to use them on brick or stone or cement.
