KSEIBI 644030 Diamond Concrete Grinding Wheel 4 1/2 inch for Polishing and Cleaning Stone Concrete Surface, Cement, Marble, Rock, Granite, and Thinset Removing, Angle Grinder Wheels Cup

This product will do all you need and fast cutting great price would buy again but finished the job and it didn’t seem to wear the cutting edge at all

Man oh man. I don't often do reviews for products that merely meet my expectations. This one blew them away. I am so pleased at how the diamond cup wheel removed the crusty thinset of tiles so I can reinstall them. I had two dozen of heavly crusted 18 inch tiles, and this product was a beast to chew through the backing (with a lot of dust of course) I used the edge of the disc to create a waffle pattern in the thinset for reliefs on their relaying. I was worried that it may wear out before I was done, but the last tile was cleaned up as fast as the first. Sure beats the disc I used about 6 years ago on a similar project which took a lot more time and heartache. I recommend this product for tile preparation whole heartedly.

This fit good on my cheaper Porter Cable grinder (PC60TAG), which is a 4.5 inch grinder with a 5/8" arbor. There were 2 rings included to change the sizes of arbor and the main one that was on there is what fit for me, but the other one looked like it would fit a slightly larger one. The size of the wheel just barely fit inside the guard, and may have slightly ground away a little, but I'm happy that it worked with the guard in place. I used the wheel to grind down a small ledge in my concrete slab to even out the floor and it worked great. This was way easier than what I had thought to do first which was to pour some leveler stuff down. The grinding was very easy to do and the wheel shows some wear, butt definitely looks like it can do more. Be prepared for lots and LOTS of dust. I was in a closed off room, and that helped, but if you have carpet or anything like that around, you should really try to reduce the dust, and make sure to have a mask of some sort. Overall, very happy with my purchase and the amount of time I saved on this hard job. Hopefully you can benefit like I did.

Only used it a short time but it worked very well.

Very good purchase

Fit right on my DeWalt angle grinder. It works best on a flat surface. Not for contours or angles. I tried it on a cinder block wall with several layers of paint on it. It stripped it right off. It will grind right through the block if you let it. Smooth even passes with little pressure does the trick. It does spit out bits of paint and concrete at high speed. PPE is required for sure.

This tool is a beast. I used it to quickly remove thinset from a concrete foundation.

This thing is tough and daily grinds concrete. Used it on two concrete pads and it still looks like new.

Cumplió con su función, la verdad es que no sé cuánta es la durabilidad por que yo solo lo usé en un pequeño espacio, quite exceso de cemento que tenía en el piso para poner mi loseta, es muy rápido así.

I used this for about 8 hours to remove 2 layers of flaking paint on concrete sidewalk and it was still working fine when I finished. It leaves a fairly smooth surface and did the job to my complete satisfaction but you need to wear a mask because fine concrete dust flies everywhere.

Hasta el momento ha funcionado muy bien.

I used the grinding wheel to remove flaking paint from concrete. It cut through the paint and scuffed the concrete. It only needs mild pressure otherwise the wheel will cut into the concrete. It prepped the surface well as i am going to tile over the concrete.

Used it more than a hundred times. Perfect everytime. Does a great job grinding.
