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.

Excellent - used this to take epoxy paint off 330 sq' sunroom floor. Worked great -- barely touched the wheel teeth, in fact 3 of the inner circle have zero wear as they never touched. The wheel's teeth a not perfectly level and so even after two hours so little had been worn that not all the teeth were touching yet.

Works very well, but for polishing. If using this in preparation for additional cementitious layers, a coarse grinding wheel will produce a better surface for mechanical bonding (aka keying). Wheel is durable, and effective.

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

I bought this to grind mortar off bricks and it worked like a charm.

Worked very well. I had to take down two high spots in a concrete floor. One was old concrete with stones and the other was new with repair material. Went through both types and ground up the stones. I was impressed.

Works very well for grinding concrete!

sharp but against dry concrete only good for light weight smoothing

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
