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

There are not enough stars to give this product. Awesome value for the money. I hope this does not come across as a fake review as many of them are. I am so happy with this product. For the price you can not beat it. The Orange, the Blue and the Green stores ( Home Depot, Lowes & Menards ) and everyone in between have similar tools like this priced outrageously high which is a rip off and an insult to consumers. Now that I have vented about the rip off stores. This tool is a monster at grinding uneven cement quickly and leaving you a beautiful finish. I had a front porch that had an uneven slab thing going on and this tool in my Matabo angle grinder made short work of that. More than an inch difference between the 2 slabs and constant over 5 feet... I was able to grind down the difference and feather it out in under an hour! 2 & a half foot wide feather over 5 feet. The bonus is the tool isn't worn out yet. Still plenty of meat left on the cutting surfaces. To say the least I did not take it easy on this tool as I was sure it would fail but what a champ this tool turned out to be. Very balanced, easy to use, no brainer. I meant to take pictures of what I did with this tool but that's my fault for forgetting before applying the epoxy finish. In addition, this tool comes with adapter rings so it can fit various types of angle grinders.

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.

This grinding wheel worked extremely well for leveling up the sidewalk

Worked well! took down the high points in the breakage of concrete.

Works very well for grinding concrete!

New to angle grinders. Had 4 trip hazards on sidewalk slabs due to tree roots. One was very bad. Bought a HF Bauer 8 amp 4.5” angle grinder. Bought a Dewalt Diamond Cutting wheel and the KSEISI Diamond Wheel. I used the Dewalt wheel to cut away and shape the concrete 1st then used the KSEISI Wheel. I was pleasantly surprised at how affective it was at grinding down the concrete. I was able to finish all four sections and still have a lot of wear left on the wheel. I did not notice any degrading in its grinding. I let the wheel do the work and did not apply a lot of pressure. As said, I am not someone with experience using an angle grinder and different wheels. Reading the reviews and watching a number of YouTube videos I was not sure what to expect. I was thinking I might need at least two wheels, maybe more. However, it exceeded my expectations, which could be different than someone with experience with the tool and job.

Thank you for fast shipping and good product. I will purchase more merchandise in the future.

Does the job, a little messy

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

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.

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.

Long lasting
