SHDIATOOL 4-1/2 Inch Turbo Row Diamond Grinding Cup Wheel for Concrete Granite Marble Masonry Brick Fits 7/8 Inch Arbor

Got this wheel to grind down thinset to the backerboard in our ex-tile bathroom. Wanted to keep the backerboard and use it as a base for laminate flooring. This wheel really took the thinset down to the backerboard underneath without scraping the backerboard to shreds. Along with a grinder kit tied to my shop vacuum there was minimal dust (until the vacuum broke a seal and emptied its contents out).BUT, the wheel worked great.

Planned on putting down an epoxy floor in the garage. I used the 4.5" diamond cutter to level out the floor. It seemed to work as advertised.

I was skeptical when i saw the review about how effective this grinding wheel was. I had a bunch of 3000 psi concrete bumps in which i wanted to level out and this wheel went through it like it was styrofoam. Amazing little grinding wheel. Does what it says it does and does it well.The concrete grinding will throw up a LOT of dust so i would strongly recommend using a good vacuum with a HEPA filter, and good mask or respirator.

Worked great. Be prepared l, it will make a mess with all the dust.

No issues with this product. Worked great

I have some problem areas in the concrete of my outside shop/garage. I've tried others but this disc with so many diamond pads makes for a smooth finish. I cleaned up about 20 sq ft total with one disc. I put a 1/4" x 4-1/2" grinding disc on my other makita metal and polished out any small imperfections. Epoxy garage floor paint is nice on a smooth concrete floor. Horrible on one that isn't. I now have a nice light grey garage/shop epoxy floor.

This work pretty well on a cement surface that was very irregular.It helped grind it down to a smooth even surface. It also looks like it will last.Not bad.

This review is for the SHDIATOOL 4-1/2 Inch Diamond Turbo Row Grinding Cup Wheel Fits 7/8 Inch Arbor. I had to cut down the high point in concrete driveway so our new car would not bottom out on it. Used a concrete cutting tool on my angle grinder to make many cuts and then chipped that away using a claw hammer. Used this Shdiatool diamond grinding cup wheel to smooth out the cuts and it worked really well. After smoothing out an area of about 14 x 48 inches there hardly seems to be any wear on this grinding wheel. I would buy this grinding wheel again.

used this to grind down some bricks that were a bit too tall (1/4" or so) for my bar top. Total around 8 ' long. Took it like a champ and left a super smooth finished. Just used a cordless ryobi angle grinder as well

We were removing some tile mortar from our sub floor this grinding cup wheel did the job for us and did it very quickly. If you don’t have a dust cover it does create a lot of dust so get the cover if this is what you are using it for.

disliked the fact that the fighting tool is not deep enough

Good quality grinding cup that lasted longer than expected. Used to grind a concrete pad about 13 ft x 7 ft with still some depth left on the tool when it was done. Ordered it again for future use.

Wow... i did rent a unit from our local store and yet it didnt the best job compare to this.
